Hadleigh Legacy 10k
South Benfleet, United Kingdom • 22 Feb 2026
The Hadleigh Legacy 10k is an award-winning trail running event held at Hadleigh Country Park in Essex. This challenging 10k race features an undulating, off-road course that includes tough hills, mud, and iconic kissing and latch gates, set within the scenic grounds of Hadleigh Castle. The single-lap route combines footpaths, fields, and trails, offering runners spectacular views and a true test of stamina and endurance. The course is GPS-measured and well-marked, though uncertified due to its multi-terrain nature. The event is popular, often selling out, and includes a bespoke medal, free photos, and prizes for leading runners, making it a top-rated 10k in the South East.
