About this Race
The Colombo Marathon is a flat coastal course through the Sri Lankan capital, tracing the Indian Ocean seafront and the city's streets on largely level terrain. The flat profile is fast on paper, but the tropical heat and humidity are the defining challenge throughout. The seaside setting and city tour define the day. The flat roads reward steady effort once the climate is respected. It suits runners who want a flat coastal South Asian race and are prepared to pace conservatively against the warmth.

Go out conservatively, hydrate early, and accept that goal pace may need to soften. The level seaside terrain offers no natural brakes. The coastal setting is scenic. Pace for the humidity and the flat profile rewards restraint.

Race History
The Colombo Marathon was first held in 1998, tracing the Indian Ocean seafront and streets of the Sri Lankan capital on a flat coastal course. After lapsing for years, it was relaunched in 2025, drawing renewed local and international interest back to the coast. The flat profile, shaped by tropical heat, remains its defining character. It continues as a flat coastal South Asian race where the climate sets the pace.
