On 13 December 2025 the Run Dorney event returns to Dorney Lake in Windsor, a venue known for its role in the London 2012 Olympics.

The route is road-based and notably flat, making it an ideal choice for those chasing personal bests or looking for a scenic winter race. With chip timing, a themed finisher medal, free official photos and post-race goodies included, the event blends performance opportunity with a welcoming atmosphere. Whether you’re a seasoned racer or stepping up to the half-marathon for the first time, this December outing offers a strong mix of challenge and accessibility.
