Epic Endurance Events
Portland, Dorset
Multi-day coastal challenges and single-day ultras on the Jurassic Coast in Dorset and the Atlantic coast of Cornwall. The three-day events can be entered for one day or all three. The format is deliberately broad — run, walk or crawl is the wording they have used since 2007. Transport runs from the event HQ to each start and back, checkpoints come roughly every 10 km, and there is hot soup at the finish. The routes follow the South West Coast Path and the navigation is yours to do.
