Half Marathon Races in Singapore: 2026 Calendar
Last updated August 9, 2026
All four half marathons on this list happen in Singapore itself, packed into a tight six-week window from late September to early November 2026. The Kiprun Singapore opens the season on September 27, followed by the Singapore Half Marathon Powered By JomRun on October 11, Garmin Run Singapore on October 25, and the Great Eastern Women's Run closing it out on November 1. Every event pairs the 21.1km distance with shorter options, from 10km down to a symbolic 0.1km at the Great Eastern Women's Run. The real choice here comes down to which weekend suits you and whether you want a mixed-field race or the women-only format.
Our pick
Our top pick is the BYD Singapore International Marathon by Adidas (84/100) -- a World Athletics Gold Label race and Boston qualifier through the Marina Bay skyline, well ahead of the field on both scale and credentials.

Frequently asked questions
When do half marathons happen in Singapore in 2026?
Four are scheduled within six weeks: The Kiprun Singapore on September 27, the Singapore Half Marathon Powered By JomRun on October 11, Garmin Run Singapore on October 25, and the Great Eastern Women's Run on November 1. All four take place in Singapore, so timing rather than location is the main thing separating them.
What distances can I run besides the half marathon?
All four events offer a 21.1km and 10km option. The Kiprun Singapore adds a 5km and 0.67km, the Singapore Half Marathon adds a 5km, and the Great Eastern Women's Run has the widest spread with 5km, 2km, and a 0.1km distance alongside the half marathon.
Is the Great Eastern Women's Run open to everyone?
Based on its name, the Great Eastern Women's Run 2026 is a women-focused event held on November 1, offering a half marathon plus 10km, 5km, 2km, and 0.1km distances. The other three races on this list don't carry that designation.
