Arc of Attrition Arc 12

The Arc 12 is a 24km coastal trail half-marathon along the South West Coast Path from near Godrevy to the finish at Porthtowan — new to the Arc of Attrition lineup in 2026. Starting at 7am as dawn breaks over the Cornish coast, the course navigates Godrevy Point, descends through coves to the aid station at Portreath, then tackles three final climbs to the finish arch at Mount Pleasant Eco Park. No support crew allowed; mandatory kit required. A perfect introduction to the Arc experience for runners taking their first steps on the South West Coast Path.
