The Colchester 10k takes place over a flat, fast, scenic and accurately measured course along roads and footpaths in Colchester, and is great for posting fast times either for a personal best or as part of a Club Championship.
Starting just outside the Garrison Running track the race is run around a circular route finishing with a final sprint outside the track with an 80m grass finish.
The course was officially re-measured in April 2025 with a few small amendments to the route to aid the running flow and improve traffic safety.
