The Standard Chartered Singapore Marathon is Southeast Asia's premier marathon and one of the largest road races in the region, drawing over 50,000 participants. The flat, fast course loops through the glittering Marina Bay district at dawn, passing the Merlion, the futuristic Gardens by the Bay, the Marina Bay Sands, and the colonial-era Padang cricket ground. Run in tropical heat and humidity — typically above 25C with 80%+ humidity — it is one of the most physically demanding Gold Label marathons on the calendar, demanding exceptional pacing and heat management.
