The Jurassic Coast Marathon is an off-road trail marathon along the South West Coast Path on the World Heritage Jurassic Coast, featuring relentless clifftop climbs and steep descents above Lulworth Cove, Durdle Door, and the lost village of Tyneham. It is a genuinely tough, hilly trail marathon with approximately 1,139m of elevation gain, and most runners finish well outside their road-marathon time.

Why attend here

December on the Jurassic Coast means crisp sea air, dramatic winter light over Durdle Door, and trails blissfully quiet after the summer crowds. Warm up post-race with a Dorset cream tea in Swanage, then explore the fossil-rich cliffs or the eerie remains of Tyneham village before the short days close in.

Course

The course rolls over the open clifftops above Lulworth Cove, Durdle Door and the abandoned village of Tyneham, based out of the Swanage area of Dorset. It is famous for huge sea views and a relentless, climb-heavy profile rather than a fast, flat layout.
