The ICA International Half-Marathon returns for its third year on December 13, 2026, promising an exhilarating running experience amid the vibrant city of Colombo. Last year's edition drew over 2,500 runners from more than 35 countries, and this time around, organizers aim to make it even larger and more inclusive. This event caters to all levels of runners with a variety of race options: the Half-Marathon (21.1KM), Challengers Run (10KM), Family Run (5KM), and an exciting addition for 2026 – the Fun Run (2KM). Participants will enjoy scenic routes that showcase Colombo's beautiful coastline and dynamic urban landscape, making it a memorable day out for both seasoned athletes and newcomers. The ICA International Half-Marathon is more than just a race; it’s a celebration of health, community spirit, diversity, and international camaraderie. Runners from South Asia, Europe, the Middle East, Africa, and beyond will come together to share in the excitement of this world-class event. Proceeds from the ICA International Half-Marathon continue to support impactful CSR initiatives across Sri Lanka, focusing on organ donation awareness, orphan care, environmental sustainability projects, and community development programs. By participating, runners not only challenge themselves but also contribute positively to society. Join us in Colombo for a day filled with energy, inspiration, and the spirit of unity as we celebrate running and its power to bring people together from all corners of the globe.

About Colombo
Learn more about the host city, Colombo.
Colombo is the largest city and commercial capital of Sri Lanka, and still perceived by many as the capital though the suburb of Sri Jayawardenepura Kotte is now the official capital. Just like any other big South Asian city, Colombo is congested, noisy, busy, and vibrant with a mixture of modern life and colonial architecture. It is the financial centre of the island and a popular tourist destination.
