What distances does the Sundown Marathon have?

When is the Sundown Marathon?

It typically runs late may (a night race). The confirmed date and registration window are set each year by the organiser, so check their official page for the current edition.

How long do I need to train for it?

For its longest distance, marathon (42.2k), a runner already training consistently needs about 12 to 16 weeks, and someone starting close to zero should give themselves 20 to 24 weeks. The marathon is an endurance and durability event as much as a fitness one. Rushing the build is the fastest route to injury.

Late May (a night race)

Sundown Marathon

Singapore's original night marathon, run under floodlights.

Singapore's first and best-known night race, run in the cool of the evening rather than the morning heat. The flagship marathon starts late on Saturday and finishes in the early hours of Sunday, which makes it a favourite for runners who train after work and race better once the sun is down.

How long to train for it

The honest answer depends on where you are starting. Two guides, for a runner already training consistently and for someone starting close to zero:

Distance	Already running	Starting from scratch
5K fun run	2 to 4 weeks	6 to 8 weeks
10K	4 to 6 weeks	8 to 10 weeks
Half marathon (21.1K)	8 to 12 weeks	16 to 20 weeks
Marathon (42.2K)	12 to 16 weeks	20 to 24 weeks

Those windows assume consistent, structured training, not just logging distance. Most recreational runners improve fastest by running most of their week easy and keeping the hard days genuinely hard. If you want a plan built around your assessment and this race as the target, our personal training for runners does exactly that. You can also predict your finish time with our running pace calculator and dial in your easy pace with the heart rate zones calculator.
