Late May (a night race)
Sundown Marathon
The Sundown Marathon, a Singapore running event typically held late May (a night race), gets its own guide here: the distances, the timing to expect, and how many weeks of training each distance needs, whether you are toeing the line for the first time or chasing a personal best.
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.
