Events Find an event Ultra Challenge - Jurassic Coast Dorset's Jurassic Coast is an amazing setting for this tough Ultra Challenge. A Poole Harbour start, on to Corfe Castle, and then the sharp ups and downs as the coastal path sweeps through Lulworth Cove and above the iconic Durdle Door enroute to Weymouth, where an epic 1st half (58km) ends. A flatter 2nd half - 42km - will take you through Chesil Beach, nature reserves, and sandstone cliffs at West Bay, before the finish in Bridport. 100km and nearly 2,700 metres of climb - a real challenge!
