The LSR Colombo Marathon is a point-to-point road marathon from Colombo to the beach town of Negombo on Sri Lanka's west coast, organised by the travel company Lanka Sportreizen (LSR) and held in early October. It began in 1998 at the Dutch Fort in Galle, with 28 foreign and 328 Sri Lankan runners, and has since been run in Galle, Negombo, Kandy, Dambulla and Colombo; it took its present name in 2004. The 20th edition was held on Sunday 4 October 2026, with about 1,000 participants from 33 countries expected, around 150 of them international runners. The full marathon is flagged off from the traffic light junction near the BMICH in Colombo 7 and passes through Borella, Dematagoda, Peliyagoda, Wattala, Pamunugama, Thalahena, Pitipana and Duwa before finishing at Negombo Beach Park. A half marathon, a 10 km fun run and a 5 km fun run take place the same day, and the full and half marathons have open and veteran categories for men and women. The event is recognised by AIMS. It is a different race from the Colombo Marathon organised by Sri Lanka's Ministry of Youth Affairs and Sports, which was held at Galle Face Green on 13 September 2026.

The Race
Colombo
The marathon was introduced by the tour operator Lanka Sportreizen to promote Sri Lanka as a destination for active holidays and sports tourism, beyond its image as a sun-and-sand destination. The first race was held in 1998 at the Dutch Fort in Galle, with 28 foreign runners and 328 Sri Lankan participants. In 2004 it was renamed the LSR Colombo Marathon, in line with other international city marathons.
