Hadleigh Legacy 10k

Hadleigh Legacy 10k is an award-winning, sell-out trail running event at Hadleigh Country Park in Essex. The 10-kilometre single-loop course blends footpaths, fields and off-road trails with an undulating, hilly profile and plenty of mud, set against views of Hadleigh Castle. The GPS-marked, multi-terrain route is clearly signed with arrows, cones and marshals; the circuit is closed to traffic but may include walkers or dogs.

Highlights include an elite wave in 2026, a vivid trail-running atmosphere, bespoke medals, free photographs and trophies. On-site parking and iconic kissing and latch gates add to the experience. Voted number 1 10k in the South East. Visit the organization's website for the most recent information.
