Thirty-five running events in Singapore for 2027, tracked as organisers confirm them: 22 coached races from HYROX Singapore and the BYD Marathon to the new Decathlon KipRun half marathon, plus 13 family fun runs and charity walks. Confirmed dates, expected windows, and registration status, curated by a Singapore studio that coaches runners year-round.

Singapore's 2027 running calendar tracks 35 events on this page: 22 coached races, led by the BYD Singapore International Marathon (expected the first weekend of December, the slot it has held for decades), AIA HYROX Singapore, the Great Eastern Women's Run and the SAFRA Army Half Marathon, plus 13 recurring fun runs and charity walks. Catalyst Performance, a Singapore studio that coaches runners year-round, updates each entry with the organiser's confirmed date and registration window as it is announced.
Most of Singapore's 2027 running calendar has not been dated yet, and that is the honest starting point for this list. As of mid-2026, organisers typically confirm a race date six to ten months out, so a 2027 event calendar built in mid-2026 is necessarily a mix of a handful of early confirmations and a longer list of expected windows drawn from each event's own history. Every entry below shows what we actually know, what we are projecting from past editions, and where registration currently stands. Racing this year instead? See the running events in Singapore for 2026 calendar for the fully dated list.
TL;DR
- As of mid-2026, almost no 2027 Singapore race has a confirmed date yet, which is normal: most organisers announce six to ten months ahead. This page tracks confirmations as they land.
- The one standout early signal: the Great Green Run's organiser has already confirmed a 2027 return with an expanded festival footprint, though no date is set.
- Two 2026 debuts, the Decathlon KipRun half marathon and Disney Run Singapore, have no prior-year pattern to project a 2027 date from; whether either becomes annual is itself unconfirmed.
- Sundown Marathon's status is genuinely uncertain heading into 2027: the organiser skipped 2024 entirely and its own site shows no verifiable 2026 edition.
- The reliable planning move while dates are unconfirmed is training-readiness, not calendar-watching; the Catalyst Healthspan Assessment shows where your aerobic and movement baseline sits so you can commit to a distance the moment a date lands.
- The full tracked list runs to 35 events: 22 coached races and 13 recurring fun runs and charity walks, with four 2026 one-off tie-ins (Pompompurin's 30th, the inaugural VIVA Charity Walk, the Pokemon 30th-anniversary run, and the rotating One Piece Run) left off because nothing points to a repeat.
- Marquee windows to pencil in from each race's own pattern: 2XU early April, Army Half Marathon late August, Garmin Run October, Great Eastern Women's Run early November, and the Singapore Marathon (BYD) the first weekend of December.

"Expected window" is our projection from each event's own multi-year pattern, not an organiser-published date. None of the 22 races above had an open 2027 registration at the time of writing. We update this table as organisers confirm.
Before race day
Is your engine ready for the race you just picked?
Take the free 5-minute Healthspan Audit: your estimated VO2 max, strength and body-composition scores, benchmarked against over 700 Singapore results.

The runners who reach the start line strong, and the finish line uninjured, do more than log kilometres. They build the strength and run-specific conditioning that mileage alone never gives. Our coaches programme that 1:1 in the CBD, paced to your race, or you can follow the strength programme yourself.
Singapore's running calendar is one of the deepest in the region: close to 40 organised events across road, trail, vertical, charity, kids and competitive formats most years. But a calendar built in the middle of 2026 for the year after is a different exercise from the dated list we publish once each race has confirmed. Organisers announce on their own schedule, and for most Singapore races that is six to ten months before race day, with registration opening somewhere in the two to four months before that. Building a 2027 page in mid-2026 means most of the calendar below is a projection, not a confirmation, and we say so plainly against every entry rather than printing a guessed date as fact.
That is also this page's real value. Every other Singapore running calendar you find published this early either copies last year's dates forward or waits until each race is confirmed and publishes late. We do neither: we track what each organiser has actually said, we show our working on the expected window using that event's own multi-year pattern, and we update the page the moment a real date lands. If you are the kind of runner who plans a training block around a calendar six months out, that combination, honest uncertainty plus a standing update, is more useful than a page that pretends to know dates nobody has announced yet.
We coach runners at Catalyst from the same starting point regardless of which race ends up on the calendar: the same 1:1 personal trainer in Singapore method, weighted to the race. Our running-specific coaching is anchored on Jeremy, a 25-plus marathon athlete with three HYROX podium finishes who writes the periodisation he uses on himself for clients targeting their first half, a sub-4-hour marathon, or a sub-3. Every runner who starts with us takes the Catalyst Healthspan Assessment, which surfaces the Cardiorespiratory Fitness score, Heart Rate Recovery, Y-Balance asymmetry and strength-pillar bottlenecks that decide what your current race-readiness actually is. That is the part of race planning you can start now, months before a single 2027 date is confirmed: know your baseline, and commit to a distance the moment a race lands on the calendar.
The biggest threat to any race-prep block is an injury in the buildup, so if something flares mid-block, treat it early: a physiotherapist settles the acute pain, and our rehab and return-to-run support rebuilds the strength to get you back on the start line. Whatever you eventually train for, our guide to the most common running injuries in Singapore covers the ones worth building prevention work against now.
The list below covers the same 22 significant races as our 2026 calendar, tracked forward into 2027 with each event's own history as the basis for what to expect. For each, we cover the 2027 status as we understand it today, what the training angle looks like once a date lands, and where the event has historically sat on the calendar. Pair this with our six best times to run in Singapore guide for the training-window constraint, and with the Heart Rate Recovery diagnostic if you are not sure whether you are aerobically ready to start a block the moment your target race is confirmed.
1. SAFRA Diaper Dash 2027 (expected May, SAFRA Punggol)
The SAFRA Diaper Dash has run in late May for two consecutive years now, 2025 and 2026, after sitting in September in the two years before that. Two years is not a long pattern, but it is the most recent signal, so a May 2027 window is our best projection until SAFRA confirms. The format stays the same regardless of date: babies aged 6 to 23 months crawl or toddle a short course at the SAFRA Punggol clubhouse, split into four age-band categories, with a themed partnership that has varied year to year.
There is no training block for the baby. The logistical exercise is registering early, because past editions have filled within the first window. For parents thinking about their own running journey, the Diaper Dash weekend is a natural anchor to build a first 5K or 10K goal around later in the year; several Catalyst clients started their own training six to twelve months after their child's first Diaper Dash. Watch for SAFRA's own event page once the 2027 edition is confirmed: safra.sg/whats-on.
2. Run for Light 2027 (expected May, Pasir Ris Park)
Run for Light has run 11 consecutive editions, most recently 23 May 2026, which makes it one of the calendar's more dependable annual fixtures even without a confirmed 2027 date. The charity race for Singapore's visually impaired community keeps its signature 1km blindfolded walk alongside a 5km fun run and a 10km competitive run, historically starting in the late afternoon to dodge the worst of the midday heat.
If the May slot holds, the 5km and 10km sit well as debut-friendly distances for runners who start a structured block in February or March. For a Cardiorespiratory Fitness score below the 50th percentile out of the 4-Pillar Assessment, we would prescribe a 12-week build to the 5km; above the 50th percentile, the 10K is achievable in 8 to 10 weeks. Check runforlight.com for the 2027 announcement.
3. National Vertical Marathon 2027 (expected May, Guoco Midtown)
Singapore's stair-climb race has drifted later within May across recent editions (early June in 2023, late May in 2025 and 2026), which puts a May 2027 window at the higher-confidence end of this list. The 2026 edition marked 30 years of the event under various organisers, run at Guoco Midtown since the venue's 2024 move from the former Guoco Tower. The training profile is materially different from a road race: quadriceps power, calf-soleus endurance and lactate tolerance under cumulative climbing load, closer to HYROX or stadium-step training than marathon prep. We have coached HYROX athletes who use the Vertical Marathon as a race-pace simulation for the lunge-and-step elements of a HYROX-prep block. Building stair-work capacity does not require waiting for a confirmed date: your own building's stairwell is a sufficient training surface starting now. Watch nationalverticalmarathon.com.
4. Great Green Run 2027 (return confirmed, date not yet set, Marina Barrage)
This is the one genuinely confirmed signal on next year's calendar. Coverage of the 2026 edition's wrap-up reported that organisers have already announced their intent to return in 2027 with an expanded festival footprint, though no date has been published on the event's own site. The Great Green Run's date history has moved around (October 2023, October 2024, no 2025 edition, June 2026), so while the return is confirmed, the month is genuinely not predictable from the pattern alone.
What stays consistent is the format: a sustainability-themed race with an eco-bazaar at the start-finish area, distances spanning an 800m kids run through 5km and 10km, at Marina Barrage. For first-time 5K runners, it has been one of the friendlier debut events on the Singapore calendar because the field spans a wide range of paces. We will update this entry the moment a 2027 date is published. Watch greatgreenrun.com.
5. Disney Run Singapore 2027 (not yet confirmed, no prior edition to project from)
Disney Run Singapore's July 2026 edition was the event's first ever in Southeast Asia, which means there is genuinely no prior-year pattern to project a 2027 date from, unlike every other entry on this list. Whether Sentosa's Siloso Beach Walk hosts a second edition next year is itself unconfirmed; a debut Singapore event returning annually is common but not guaranteed. If it does return, expect the same non-competitive format: 1km, 3km and 5km distances aimed squarely at families, heavily themed photo opportunities and character meet-and-greets, run along Sentosa's southern coast. We are treating this one as genuinely open rather than assuming a repeat. Watch raceroster.com and the official Sentosa events page for any 2027 announcement.
6. Lazada Run 2027 (expected July, low confidence, Singapore Sports Hub)
Lazada Run is the least consistent event on this list to project forward: an inaugural 2023 edition, no confirmed 2024 edition found, then 2025 and 2026 both landing in late July. If the two most recent years hold as the new pattern, a July 2027 window is our best guess, but we would flag this as our lowest-confidence projection among the numbered races, given the gap year in the middle of its short history. The half marathon distance is the standout when it does run: relatively few Singapore mid-year races offer a 21.1km, and the Lazada Half has been a natural mid-year confidence-builder for runners on a December marathon block. Watch lazada.sg/lazrun and the organiser's own Facebook page, which has been the more reliable source for date announcements than the static event page.
7. Pocari Sweat Run 2027 (expected early September, Singapore Sports Hub)
Pocari Sweat Run has landed in the first half of September for three consecutive years: 9 to 10 September 2023, 6 September 2025, 5 September 2026. That is a genuinely stable pattern, which makes early September 2027 one of the more confident projections on this list, even without an organiser announcement yet. The 5:30am start has consistently made this one of the cooler races on the calendar despite sitting in the year's hottest stretch, and it fits well as a pre-October tune-up for runners building toward Garmin Run or the BYD Marathon later in the year. Watch jomrun.com for the 2027 registration page.
8. Garmin Run Singapore 2027 (expected October, Marina Barrage)
Garmin Run has run three consecutive Octobers since its 2024 debut: 13 October 2024, 12 October 2025, 25 October 2026, drifting slightly later each year. October 2027 is a reasonably confident projection on that basis, though the exact date within the month has moved. The event was rebranded in 2026 from the Garmin Run Asia Series to the Garmin Run Marathon Series as it expanded to city races outside Asia, which is a sponsor-scale signal rather than a discontinuation risk for the Singapore leg. For runners targeting a December marathon, the Garmin Half has functioned as a natural confidence-building race roughly six weeks before race day. Watch garmin.com.sg/event for the 2027 information page once it opens.
9. Great Eastern Women's Run 2027 (expected early November, The Kallang)
The largest women-only race in Singapore has run in early November for three consecutive years (1 November 2023, 27 October 2024, 9 November 2025, 1 November 2026), which makes early November 2027 a confident projection. The 2026 edition marked the 20th edition of a race the same title sponsor has backed since 2006, with no signal of discontinuation. The distance lineup, when it repeats, has been the most comprehensive on the year-end calendar: a 21.1km half marathon down to a 100m Princess Dash for young children, plus a 2km Mummy-and-Me category. The event has consistently drawn 12,000 to 15,000-plus participants. Watch greateasternwomensrun.com.

10. AIA HYROX Singapore 2027 (not yet confirmed)
HYROX's Singapore calendar has itself changed shape: a single April edition in past years expanded to two 2026 editions, April at the National Stadium and a record three-day November weekend at Singapore Expo. No 2027 Singapore date has been published on HYROX's own event pages as of this research, but the global HYROX calendar is expanding rather than contracting, with new markets and a 2027 World Championship already announced elsewhere in the region. We see no signal that Singapore drops off; we simply do not have a 2027 date to publish yet.
This is a factual calendar listing, not a Catalyst service description; HYROX is the event's own trademark. If a similar twice-yearly pattern holds, expect an April and a November window. Our guide to training for HYROX in Singapore covers the engine-first method and a 12-week plan you can start well before a date is confirmed. Watch hyrox.com/event/aia-hyrox-singapore.

11. Sundown Marathon 2027 (status genuinely uncertain)
We are flagging Sundown differently from every other event on this list: its 2027 status is uncertain enough that we would not call it a safe "expected" entry. The organiser skipped the 2024 edition entirely amid reported sponsorship difficulty, refunding entries, and at the time of this research we could not verify a confirmed 2026 edition on the organiser's own site, which shows only thin, dated content. A 2025 edition reportedly ran, but even that is not cleanly confirmed. Be careful of copycat domains using a near-identical name; they are not the organiser.
Historically, Sundown was Singapore's only major night marathon, run through the Sports Hub in the cooler overnight hours with distances up to the full 42.2km. If it returns, that format is the draw. But we would treat a 2027 Sundown Marathon as speculative rather than expected until the organiser publishes something concrete, and we will update this entry the moment that happens either way.

12. BYD Singapore International Marathon 2027 (expected early December, F1 Pit Building)
Singapore's flagship marathon has run the first weekend of December without exception for decades, most recently 4 to 6 December 2026 as the event's 44th edition. That unbroken pattern makes early December 2027 the single most confident projection on this list. The 2026 edition confirmed BYD as the new title sponsor, replacing Standard Chartered, with adidas as presenting sponsor and SG International Marathon Pte Ltd continuing as organiser; nothing points to a further name change for 2027.
For a debut half marathon at BYD, we would programme a 16-week build; 18 to 22 weeks for the full. Because this is the one race on the list with a genuinely predictable window, it is also the one worth structuring a full year's training calendar around even before the exact date is confirmed: registration for the 2026 edition closed 30 September, so expect a similar late-September 2027 close. Watch singaporeinternationalmarathon.com.

13. 2XU Compression Run 2027 (expected early April, F1 Pit Building)
2XU Compression Run has held a stable early-April slot for years, most recently 5 April 2026, with no discontinuation or sponsor-change signal. Early April 2027 is a confident projection on that basis. When it runs, the flat, fast course at F1 Pit Building has made it a popular pick for runners chasing a personal best across 5km, 10km and the 21.1km half. If 2027 follows the same window, it sits early in the year, which suits runners who want their base training to start over the December-to-January period. Watch 2xurun.com.
14. Income Eco Run 2027 (expected mid-April, Bayfront Event Space)
Income Insurance's beginner-friendly race has run mid-April in recent years, most recently 19 April 2026. Mid-April 2027 is our projection, with no changes signalled to the event's stable distance ladder of 3km through 21.1km. It has been one of the more approachable half marathons on the calendar for runners stepping up from a 10K for the first time. Watch income.com.sg/ecorun for the 2027 announcement.
15. Unlabelled Run 2027 (expected early June, The Kallang)
Unlabelled Run's 2026 edition, its 10th, ran 6 June at The Kallang. A decade of consistent editions makes early June 2027 a confident projection, run by The New Charis Mission. The 5km and 10km distances have positioned it as an unbranded mid-year tune-up race, useful for runners calibrating pace ahead of a second-half-of-year target. Watch unlabelledrun.org.
16. GU Forest Force Run Series 2027 (expected mid-year, Dairy Farm Nature Park)
Singapore's trail series, organised by King Trail Events, has run a mid-year two-race window for several years, most recently 5 July and 13 September 2026 as the GU Forest Force Run Series. Worth flagging: the title sponsor has changed before, from Buff to GU between 2025 and 2026, so while the organiser and format are stable, the 2027 branding could shift again even if the dates land in a similar window. The 21km and 30km trail distances at Dairy Farm draw a different training profile from road racing; a 21km trail effort sits closer to a 25 to 28km road equivalent in physiological cost. Watch kingtrailevents.online.
17. Singapore Half Marathon and Run 2027 (expected July, East Coast Park)
The Singapore Half Marathon and Run, organised by United World Sports Management with the FTC Foundation and marketed under the "Run as One" banner, ran 19 July 2026 at East Coast Park. We could not confirm a pre-2026 edition history in our research, so a July 2027 projection rests on a single data point rather than a multi-year pattern; treat it as a reasonable but lower-confidence guess. Watch the organiser's RaceRoster listing for the 2027 registration page once it opens.
18. SAFRA Bay Run and Army Half Marathon 2027 (expected late August, running late on its own cycle)
One of Singapore's largest mass-participation races, historically 40,000 to 50,000 runners, has typically landed in late August. Worth noting: at the time of this research, SAFRA had not yet published even a 2026 date, which is genuinely late against its own announcement cycle. That makes late August 2027 our historical-pattern projection, with the caveat that the organiser is running behind its usual timeline this cycle, which could shift the whole sequence later. Watch safra.sg for both the delayed 2026 confirmation and, eventually, 2027.
19. Running Lab Run 2027 (expected late August, East Coast Park)
Running Lab Run's 2026 edition was its fourth, held 30 August at East Coast Park with a consistent 5:30am start. Four straight years at the same venue and roughly the same date makes late August 2027 a confident projection. It has functioned as a committed 10K runner's benchmark race rather than a beginner event. Watch runninglabrun.com.
20. Yellow Ribbon Run 2027 (expected September, venue genuinely uncertain)
Yellow Ribbon Run, run by Yellow Ribbon Singapore and the Singapore Prison Service, has held a September slot in recent years, most recently 20 September 2026. But the 2026 edition also moved venue for the first time, the organiser's own description was "heads to the city for the very first time", relocating to the National Stadium from its previous location. That makes the date a reasonable projection but the venue a genuinely open question for 2027: a first-year relocation does not tell you whether the new venue sticks. Watch yellowribbonrun.sg.
21. Decathlon KipRun Run 2027 (not yet confirmed, no prior edition)
The Decathlon KipRun Run held its first-ever Singapore edition on 27 September 2026 around the Marina Bay area, a half marathon plus 10km, 5km and kids' dash under Decathlon and MetaSport. Like Disney Run, this is a debut event with zero track record, so we are not projecting a 2027 date; whether Decathlon's global KipRun format becomes an annual Singapore fixture is itself the open question, not just the date. Watch decathlon.sg/s/the-kiprun-singapore and metasport.com for any 2027 signal.
22. Run For Hope 2027 (expected November, running late on its own cycle)
Run For Hope, the Four Seasons Hotel Singapore and National Cancer Centre Singapore charity run at Marina Barrage, is a genuinely long-running event, its 32nd edition in 2025, but at the time of this research the organiser's own site still showed 2025 as the current edition with only a "#RFH2026" hashtag as a forward signal; a third-party aggregator's claim of a 29 November 2026 date was not corroborated on the organiser's own site. That puts this event in a similar running-late position to SAFRA's Bay Run: a November 2027 window is our historical projection, but the organiser is behind its own typical announcement pace this cycle. Watch runforhopesg.com for both the overdue 2026 confirmation and the 2027 follow-on.
Family, charity and character fun runs (2027)
Beyond the 22 coached races above, Singapore's calendar carries a thick layer of participation-first family runs, charity walks and cause events that do not need a structured training block, just a morning and a reason to show up. We track 13 of these forward into 2027 based on how consistently each has repeated. Four 2026 events do not appear below: Pompompurin's 30th Anniversary Run and the Pokemon 30th-anniversary run were explicitly tied to Sanrio and Pokemon global anniversary campaigns with no prior Singapore edition and no signal of a repeat; the inaugural VIVA Charity Walk marked VIVA Foundation's 20th anniversary with no continuation evidence yet; and One Piece Run is one of several rotating licensed-character runs the same organiser has run under different IP each year, so a One Piece repeat specifically is not a safe bet even though the organiser's format continues. If any of the four are confirmed for 2027, we will add them back with a source.
| Event | 2027 status | Historical window |
|---|---|---|
| Skechers Friendship Walk | Expected (10th edition) | Late May |
| Cold Storage Kids Run | Expected | Late June |
| Cinnamoroll Run | Likely, thinner record (2 years) | Mid-year |
| Snoopy Run | Likely, thinner record (2 years) | Mid-year |
| 7-Eleven Run | Expected (3rd edition) | Late August |
| Walk for Our Children | Expected | August |
| Race Against Cancer | Expected (11th edition) | Late September |
| POSB PAssion Run for Kids | Expected | Late October |
| Pink Ribbon Walk | Expected | October, breast cancer awareness month |
| SparkAbility | Expected | September |
| Stride for Good | Expected | October |
| Run For Singapore | Expected, likely renamed "SG62" | August to September, virtual |
| Santa Race for Wishes | Expected (8th consecutive year) | December, virtual |
"Historical window" reflects the month each event has run in past editions, not a confirmed 2027 date. None had a 2027 date published at the time of writing.
Two entries are worth a closer look. Run For Singapore is RunSociety's virtual National Day challenge: the 2025 edition ran as "SG60" for Singapore's 60th birthday, and the 2026 edition as "SG61", each open roughly two months over August and September with a 6.1km or 61km distance choice covered on your own schedule, running, walking or cycling. That two-year naming pattern makes an "SG62" 2027 edition the logical continuation, though nothing carries that branding yet. It remains a low-pressure way to hold a consistent-mileage goal through the hottest stretch of the year, useful as base-building ahead of a year-end target like the Garmin Half or the BYD Marathon once those dates land.
Race Against Cancer is one of the more dependable entries on this whole page: its 10th anniversary in 2026, run by the Singapore Cancer Society with Singtel as anchor sponsor since 2008, has raised roughly SGD 8.2 million across a decade of editions. An 11th edition in 2027 is about as safe a projection as anything on this list, even without a date yet.
How to plan a race before the date is out
Most of the events above do not have a 2027 date yet, which means the usual advice, "pick your race, then count back the training weeks", does not fully apply this early. What you can do now is separate the two decisions: get your training baseline right immediately, and lock the specific race target the moment a date is confirmed.
Start with your fitness baseline. We measure this in the Catalyst Healthspan Assessment through Cardiorespiratory Fitness (a YMCA 3-minute step test, an estimate of VO2 max without volitional failure), Heart Rate Recovery, grip strength percentile and Y-Balance asymmetry. Runners below the 50th percentile for their age and sex band should plan around a 5K or 10K target once a race is confirmed, not jump straight to a half or full marathon. Runners between the 50th and 75th percentile can target a half marathon in 12 to 14 weeks or a full in 18 to 22 once the date lands; above the 75th percentile opens the door to a competitive HYROX race or a sub-3:30 marathon attempt. Our VO2 max guide covers why the step test is the right diagnostic to run now, months ahead of any confirmed race.
Next, decide your target honestly. "I want to finish a half marathon" is a 14-week block once you have a date. "I want to run a half marathon at 5:00 per km" is a 16-to-20-week block with structured intensity work and a tune-up race four to six weeks out, which is one more reason BYD's predictable early-December window (the one date on this page you can plan a full year around already) is worth anchoring a 2027 training year to, even before every other race confirms.
Third, protect the training time you can actually defend on the calendar. Three to five hours a week of running plus strength is the threshold for meaningful adaptation; below three hours, most adults plateau within 6 to 8 weeks. Our coached clients average 4 to 5 hours a week across three or four runs and one or two strength sessions, a load working adults with executive jobs can sustain for 16-week blocks once a race is locked in. Pair that with the right time-of-day window for Singapore's climate (our guide on the six windows covers this), and the race-day result follows.
Most of this calendar is not dated yet, and that is fine. The training baseline is the part you control regardless of when a race lands, and it is the part that decides whether you are ready the day a date finally is confirmed.
For runners with no current race in the calendar, the lowest-friction starting point is the 4-Pillar Healthspan Assessment: sixty minutes in studio, four pillars measured, and you walk out with the data that tells you what distance is realistic once a 2027 race is confirmed, plus a printed Healthspan Report you keep regardless. Our free VO2 max calculator and fitness age calculator are lighter-weight starting points if you want a baseline read before booking anything. For runners outside Singapore, or anyone who wants the same periodisation without the studio, our online coaching runs the identical assessment-to-race-date approach remotely.
Frequently asked questions
Q. Why don't most Singapore races have a 2027 date yet?
Most Singapore race organisers confirm their next edition's date six to ten months before race day, with registration typically opening two to four months before that. Because this page is being tracked in mid-2026, most 2027 dates genuinely have not been decided by the organisers yet, not because the information is missing. The exception on this page is the BYD Singapore International Marathon, which has run the first weekend of December without exception for over a decade, and the Great Green Run, whose organiser has already confirmed a 2027 return even without a date.
Q. Which Singapore race is safest to plan a 2027 training year around?
The BYD Singapore International Marathon, historically the first weekend of December every year, is the single most predictable date on this page even before an official 2027 announcement. If you want to anchor a full year's training calendar to one target now, that is the one with the longest unbroken pattern behind it.
Q. Is Sundown Marathon still running?
It is genuinely unclear. The organiser skipped the 2024 edition entirely and, as of this research, the organiser's own site does not clearly confirm a 2026 edition took place. Treat any 2027 Sundown Marathon listing you see elsewhere with caution unless it links back to the organiser's own current site, and watch for copycat domains using a near-identical name.
Q. When is the Singapore Marathon 2027?
The BYD Singapore International Marathon, the race most people mean by the Singapore Marathon, has run the first weekend of December without exception for decades, so the 2027 edition is expected in early December 2027. The organiser has not published the exact date yet; 2026 registration closed 30 September, so expect a similar 2027 timeline. Watch singaporeinternationalmarathon.com.
Q. When is HYROX Singapore 2027?
No 2027 Singapore date has been published on HYROX's own event pages yet. Singapore hosted two 2026 editions, April at the National Stadium and 27 to 29 November at Singapore Expo, and the global calendar is expanding rather than contracting, so a similar April and November pairing is the reasonable expectation. Watch hyrox.com for the official announcement.
Q. When is the SAFRA Bay Run and Army Half Marathon 2027?
Historically late August, but treat 2027 as unconfirmed: at the time of writing SAFRA had not published even its 2026 date, which is unusually late against its own announcement cycle. It is one of Singapore's largest races, historically 40,000 to 50,000 runners, so registration tends to open months ahead once a date lands. Watch safra.sg.
Q. How long does it take to train for a half marathon in Singapore from scratch?
For most working adults with no current running base, 14 to 16 weeks of structured training is the honest answer for a debut half marathon, regardless of which 2027 race you eventually target. The block builds long-run distance progressively from 6km to 18km, with three runs a week (one Zone 2 base, one interval session, one progressively longer Sunday run) plus two strength sessions. You can start this block before a specific race date is confirmed and simply extend or compress the final taper once one is.
Q. Is there a trail running race in Singapore in 2027?
Likely, based on pattern: the GU Forest Force Run Series has run a mid-year two-race window (a 21km and a 30km trail event) at Dairy Farm Nature Park for several consecutive years, though the title sponsor has changed before and could again. Trail distances are not directly comparable to road distances; a 21km trail route sits closer to a 25 to 28km road effort in physiological cost.
Q. Do I need to wait for a confirmed date before I start training?
No, and waiting is the more common mistake. Your aerobic and strength baseline, measured once through the Catalyst Healthspan Assessment, tells you what distance and timeline is realistic the moment any race on this page confirms. Runners who build that baseline ahead of time are ready to commit immediately; runners who wait for a date before starting anything lose weeks they cannot get back once the training window is finally clear.
This page will look very different by the end of 2026, as organisers confirm their 2027 editions one by one. The pattern across nearly every entry above is the same regardless: Singapore's climate and its 12-to-22-week race-prep windows do not care whether a date was announced early or late, and the runners who hit a personal best are the ones who protected the training weeks, not the ones who watched the calendar the closest.
The Catalyst Healthspan Assessment is the entry point that works no matter which 2027 race ends up on your calendar. Sixty minutes in studio, four pillars measured, and you walk out with the data that tells you what is realistic once a date lands, plus a printed Healthspan Report you keep regardless of whether you train with us.
