Organiser's Description

Dorney Lake, home to London 2012′s Olympic rowing events, is a perfect environment for running as well as rowing. The flat course is ideal for a chip timed personal best over the Marathon and Half Marathon distances.

With events around the Country being cancelled, we are pleased to be able to give you the opportunity to complete a marathon or half marathon distance in a small scale, socially distanced environment. The event is restricted to just 600 runners and held in traffic free and private grounds. It will follow a time trial format, with athletes being kept socially distanced on the start line and starting in small waves, with the fastest predicted times going off first.
