The Greenway Challenge
Letchworth Garden City, United Kingdom • 10 May 2026
Event overview
The Greenway Challenge on 10 May 2026 is a self-guided run around the Garden City Greenway in Letchworth Garden City. The event is held under UK Athletics (UKA) rules and has a minimum age of 17. It is described as a run rather than a race because the course includes road crossings.
Course and logistics
The route starts and finishes at Standalone Farm in Letchworth Garden City and follows the Greenway in a clockwise direction. The course length is approximately 13 miles. Participants receive a map, written instructions and a GPX file to follow the route; navigation is the participant’s responsibility. Marshals will be present at road crossings but will not stop traffic, so participants are responsible for their own safety. There is a time limit of three hours, after which marshals will stand down. All finishers will receive a wooden medal made by a Garden City company, and refreshments and cake will be available at the finish.
Entry and charity
Entry fee is £20, rising to £22 on 1 January 2026. A £2 discount applies for members of clubs affiliated to their national association (for example, England Athletics). Entries may be amended or transferred via the confirmation email link. All profits from the event will be donated to the club’s chosen charity, GRIT, which supports teenagers with mental health issues; additional donations can be made during registration.
