Singapore Running
A guide to Singapore's major races, built for runners deciding what to enter and how to prepare. Each race has its own page: what it is, the distances it offers, and, the part most calendars skip, how many weeks you need to train for it. For the full dated calendar, see the 2026 running events calendar and the 2027 first look.
