Hadleigh Legacy 10k

About

This sell-out event offers a unique opportunity to test your stamina and endurance to the limit. You can expect an exceptionally challenging but exhilarating course with spectacular views. Be prepared to conquer some seriously tough hills and, in the spirit of trail racing, expect mud, mud, mud!

Route Information
The Hadleigh Legacy 10k enjoyed a new and exciting course in 2025, crafted in response to your suggestions and staying true to the award-winning race's original design. And, we are delighted to report, that after some fantastic and positive feedback last year, we are looking forward to returning to this specially crafted course for 2026 which enhances the runner experience while maintaining the exceptional trail challenge it's renowned for.

Expect tough hills, mud (and more mud!), and iconic kissing and latch gates, all set within the stunning grounds of Hadleigh Castle. This off-road 10k is trail running at its finest, promising a mix of footpaths, fields, and trails that will test your endurance and reward you with unmatched finish-line joy.

The GPS-measured route, while uncertified due to its multi-terrain nature, will be clearly marked with route arrows, cones, and marshals. Please note, the circuit is closed but may include occasional walkers or dog walkers - exercise caution while running.

Elite Wave
2026 will, once again, see an elite wave with further wave starts to follow after as part of the main race; details of this will be included in the race-day info sent out via email a few days before the event.
