Overview
A tough challenge and a route that’s simply stunning, and an overwhelming sense of achievement as you finish. From a new start venue in Corfe Castle it’s across the ‘Isle of Purbeck’ to Swanage, along the coast, and then looping back towards Corfe Castle for lunch at 25 km. Then we head west along the Purbeck Ridge to Lulworth Cove and Durdle Door, en route to Weymouth at the 58km halfway stop with welcome hot food. It’s on to the far end of Chesil Beach, then to West Bay with its famous sandstone cliffs, before finally reaching the Bridport finish line where a big celebration awaits!

Such an amazing event. 1st Half conquered. It was brutal and the hills kept coming. Everyone was kind and chatty and checked on each other. We had a fab time. Scenery was stunning. Will be back for second half next year.
