Run Dorney Lake Half Marathon

Run Dorney Lake offers a 5K, 10K and Half Marathon at the site of London’s 2012 Olympic rowing events. Set at Dorney Lake in Windsor, Buckinghamshire, the flat, road-based course is ideal for a chip-timed personal best. The Half Marathon uses four laps with a U-turn each loop, while the 10K is two laps and the 5K a single lap, with modest elevations (8m, 15m and 27m total per distance).

Participants enjoy a friendly marshal-led atmosphere, a bustling event village, and post-race goodies. Each runner receives a unique themed medal and free race photos, with sustainability initiatives noted by the organizers. Visit the organization's website for the most recent information.
