Sundown Marathon was created in 2008 as part of a unique training programme 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 in 2019 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.
In 2015, OSIM became Sundown Marathon’s title sponsor and the race is named the OSIM Sundown Marathon Singapore. It is also Singapore’s first night race to be nominated twice for the prestigious International Sports Event Management (ISEM) Awards and, more recently, Marketing Events Awards for the Best Sport Oriented Event.
