About the LSR Colombo Marathon
LSR's flagship road race brings Sri Lankan and international runners to the capital for a full marathon supported by shorter events. The marathon has its own 42.195-kilometer identity and is listed by AIMS as a member race. Direct organizer enrollment is available for the current edition.
Course
This is a capital-area road marathon built for an early start in tropical conditions. The organizer plans aid and medical support along the route, while the full marathon remains distinct from the shorter races on the program. Runners should prepare for sustained heat management rather than expecting cool-season pacing conditions.
Race-day weather
Colombo is hot and humid year-round, and an early start only partly limits the tropical load. Warm rain is possible, while cloud cover can hold humidity close to the road. Conservative early pacing, regular fluids, and attention to cooling are central to a sound race plan.
