Hurtwood 50K Trail Running Ultramarathon
The Hurtwood 50K is a trail running event based in the town of Dorking. The route follows the Greensand Way into the forested Surrey Hills, a designated Area of Outstanding Natural Beauty. The course is designed as a "lollipop" layout, consisting of an out-and-back section supplemented by a 5-mile loop.
Following the trail through woodlands, valleys, and along ridgelines, the course traverses several notable points within the area known as The Hurtwood, including:
- 50 km
Participants travel over Leith Hill, Holmbury Hill, and Pitch Hill. While primarily following the Greensand Way, a short western loop takes runners off this path before they rejoin it for the return journey to the finish line. The route is fully signed with reflective markers and supported by four aid stations located at miles 7, 13, 18, and 24.
The event features an overall time limit of approximately 10 hours, with a final cut-off at 7:30 pm. Due to the early December date, participants finishing toward the end of the time limit will require a headtorch for the final sections of the course. A mandatory kit list is required for all participants.
Electronic timing provides live leaderboards for tracking progress. Finishers receive a medal, and the event serves as a qualifier for the UTMB runner performance index. Registration and parking are available at the Dorking Sports Centre. Visit the organization's website for the most recent information.
