Crowborough 10K & 5K are tarmac road races in Crowborough, East Sussex, held on a Sunday morning in November. They feature road closures and a challenging course. The 10K, hosted by Crowborough Runners, is part of a local race tradition spanning over thirty years. The 5K was introduced later for participants seeking the same event at a shorter distance.
Both races commence simultaneously on roads around the town. The 10K involves two laps, while the 5K completes one. The course is accurately measured. The 10K is a qualifying race for the Sussex Grand Prix, attracting runners of various abilities, not exclusively club athletes. All finishers are awarded a custom medal, top runners contend for trophies and prizes, and cakes are available at the finish.
