About OSIM Sundown Marathon Singapore

Singapore’s largest night marathon, the Sundown Marathon, is looking to redefine the art of night running and is designed as the perfect rush of adrenaline for everyone!

Sundown Marathon injected a jolt of energy into Singapore’s running scene when it became the nation’s first night marathon in 2008, and has become Asia’s largest night marathon.

Being Singapore’s first night race to be nominated twice for the prestigious International Sports Event Management (ISEM) Awards and Marketing Events Awards, for the Best Sport-Oriented Event, Sundown Marathon has fearlessly gone where other running events fear to tread.

Sundown Marathon puts on a show under the stars at the renowned F1 Pit Building, dazzling runners with flaming pyrotechnics during flag off, live concerts by local bands, a food and beverage village and VIP packages.
