EnduranceLife | Dorset 2026

EnduranceLife Dorset is a December trail running event based around Swanage on Dorset’s Jurassic Coast, offering 10K, half marathon, marathon, and ultra distances. The 10K race has 774 feet of climbing, the marathon climbs 3,736 feet, and the ultra covers 53.4 km with approximately 1,960 metres of elevation gain. The course consists of trail and grass, with the organiser describing the terrain as extreme, distinguishing it from a road race with minor dirt sections. The routes follow the Jurassic Coast Path, a World Heritage landscape known for its exposed geological history along the cliffs and coastline. Participants include 10K runners testing themselves on steep coastal paths and ultra runners aiming for a UTMB Index result; finishers in all distances earn points for the Endurancelife season leaderboard. Registered runners must check in online before race day, confirm details like emergency contacts, and view a mandatory safety video. Post-race, The Anchor Inn in Swanage is suggested for food and drinks.
