The Three Forts Challenge on 3 May 2026 includes a Marathon, Half Marathon and a 5 Mile trail race in West Sussex.

The Three Forts Marathon, also called "The Tough One", is 27 miles of mixed South Downs terrain featuring steep climbs, stiles, and rough tracks underfoot. The journey takes runners past iconic landmarks such as Chanctonbury Ring and Cissbury Ring, with panoramic views across the countryside.

The Half Marathon takes a shorter route to Steyning Bowl and picks up the last part of the Marathon route. It offers a unique blend of rugged terrain, steep climbs, and picturesque views.

The 5 Mile Trail Run is for those wanting a shorter distance with a scenic mix of rolling hills, rough tracks, and grassy trails.
