Sundown Marathon

Welcome to the

OSIM Sundown Marathon 2023

Sundown Marathon was created in 2008 as part of a unique training program for ultra-marathons that require running through the night. Since then, as Singapore’s first official night marathon, the Sundown Marathon has grown from strength-to-strength, beginning with 6000+ participants in the inaugural race in 2008 to a total of 25,000 participants across all four categories, making it Asia’s largest night marathon. Participants have included tourists and professional runners from the UK, USA, France, China, India, Japan, Philippines, Indonesia, Malaysia and Taiwan.
