Richmond Park Marathon & Half Marathon 2026

The Richmond Park Marathon & Half Marathon takes place in late summer within Richmond Park, southwest London. Both the full 26.2-mile marathon and a half marathon are offered. The start and finish are located near Sheen Gate on the park's north side, placing runners within one of London’s largest open green spaces instead of city streets. The marathon consists of three laps, with variations between them. The first lap is 12 miles, encircling the park's perimeter and passing through its center. The second and third laps follow the Tamsin Trail for 7.1 miles each. The half marathon follows a single-lap route, offering participants the Richmond Park setting without the full marathon distance.
