Colombo Half Marathon

Course & Elevation

The ICA International Half-Marathon is a half marathon on the Colombo seafront, organised by the Indian Cultural Association (ICA) Sri Lanka, with the start and finish at Galle Face Green. It was first held on 1 September 2024, and the 2026 edition, the third, is scheduled for December. The route follows the coast along Marine Drive and Galle Road; in 2024 it also took runners past Beira Lake and through the Colombo Fort area before returning to Galle Face Green. The organisers describe the course as flat, fast and coastal, and say the courses are measured and certified under the World Athletics International Measurement Programme in cooperation with AIMS. A 10 km Challengers Run and a 5 km Family Run take place on the same morning, and a non-competitive 2 km Fun Run was added in 2026. The race starts at dawn. The first edition drew 732 athletes from 20 countries, and the organisers report that the 2025 edition attracted over 2,500 runners from more than 35 countries. The event is run in support of causes including clean water, organ donation and children's homes in Sri Lanka.
