The Colombo Half Marathon is one of Sri Lanka's most popular road running events, attracting thousands of local and international participants each year. The race takes runners through the heart of Colombo, passing landmarks including Galle Face Green, Viharamahadevi Park, and the Colombo waterfront. The flat city course makes it fast and accessible for runners of all experience levels.
The event typically offers 5K, 10K and 21.1K categories, making it suitable for first-time fun runners through to experienced half marathoners chasing personal bests. Post-race celebrations include food, music and prize ceremonies at the finish area.
Training in Sri Lanka's tropical heat requires adjustment. Run in the early morning (5–7am) to avoid the midday heat and humidity. Galle Face Green and Viharamahadevi Park are popular training routes in Colombo. Stay hydrated — drink 2–3 litres of water daily and add electrolytes during long runs. Give yourself at least 12 weeks to prepare for the 21.1K.
Colombo has a full range of accommodation from budget hostels to five-star hotels. For marathon weekend, book accommodation close to Galle Face Green or Kollupitiya for easy access to the start line. Budget travellers can find good hostels in the Fort and Pettah areas.
