Singapore Half Marathon 2026

JomRun's Singapore Half Marathon 2026 lines up three distances at Marina Barrage: a 21.1K, a 10K and a 5K. If you want the long one, the 21.1K is as far as the event goes — there is no full-marathon category — and it is the only distance that is timed, chipped with RFID and paired with a finisher jersey. The 5K and 10K are untimed, which suits anyone who would rather run the route than race the clock.

Everything starts from Marina Barrage on Sunday 11 Oct 2026, with a 3.30am flag-off. That is a very early start, so sort your transport and an early night beforehand. Decide what you are after: a chip time and a finisher jersey over 21.1K, or an untimed 5K or 10K where the finish line is the only target.
