The race
The Three Forts Challenge takes place on Sunday 2 May 2027, based at Lancing Manor Leisure Centre in West Sussex: a Sussex tradition since 1977, nicknamed 'The Tough One', with profits going to Ferring Country Centre and other local charities.
The routes cross the South Downs past Cissbury Ring, Chanctonbury Ring and Devil's Dyke, on chalk, flint and grass paths with few road sections. Marathon at 9:00 (£49, 6-hour limit), half at 9:15 (£39) and 5 miles at 9:30 (£20); dogs are welcome too.
