Known as "The Tough One" the Three Forts Marathon (27.2 miles) includes a total of c. 3450 ft of climb with stiles and rough tracks underfoot. The route runs northwards from Hill Barn to Cissbury Ring, then eastwards towards Coombs then to Botolphs and the River Adur crossing. The route then goes to Devil’s Dyke and back to the River Adur. It continues on the South Downs Way to Chanctonbury Ring, where it swings south-west to Findon Park Farm. It stays on public bridleways to Cissbury Ring and back to Hill Barn. 

The Marthon has a strict 6 hour time limit.  The event is fully supported by our Aid Stations for all of this time.

The Half Marathon, with a total climb of c.1450 ft, takes a shorter route to Steyning Bowl and picks up the last part of the Marathon route. The map shows the route in more detail and can be used in conjunction with the appropriate OS map.

The NEW event for 2023 is a 5 Mile Trail Run for those wanting a shorter distance but with the challenge of the hills.

All runners and who complete the course will receive a 3FC medal and 2022 technical T-shirt.  

Mike Airey, 3FC Race Director, on behalf of the 3FC committee
