The Hanoi Marathon, officially the Techcombank Hanoi International Marathon, is a road race through the Vietnamese capital held on a Sunday in early October. It is organised by the Hanoi Department of Culture and Sports with Techcombank and Sunrise Events Vietnam, and it was first run in September 2022; the 5th edition took place on 4 October 2026. The full marathon starts at 4:00am at the Ba Kieu Temple garden on Dinh Tien Hoang Street in Hoan Kiem. Runners pass through the Old Quarter and around West Lake, cross the Nhat Tan Bridge into Dong Anh, return over the Dong Tru Bridge to Long Bien, and finish at Vinhomes Riverside. The organisers say the route passes 37 landmarks, among them Hoan Kiem Lake, the Opera House, St Joseph's Cathedral and the Ho Chi Minh Mausoleum. The half marathon starts at 4:30am with a cut-off of 8:45am, and 10 km and 5 km races run on the same day. The marathon has a 6 hour 30 minute limit, with the course closing at 10:45am.
