About
Introduction Take on a rugged half marathon around the Isle of Portland as part of an Epic Endurance event day on the Jurassic Coast. The Portland Loop Challenge is designed for runners who want a tough but achievable coastal challenge. Covering 13.1 miles around Portland, the route takes in dramatic sea views, exposed clifftop sections and constantly changing terrain. This is not a road half marathon built for PBs. It is a proper endurance-style half marathon with a raw coastal feel, ideal for runners who enjoy a challenge and want to be part of a unique event atmosphere. With Event HQ based on Portland and The Oner taking place on the same day, the whole day will have a real endurance event feel from start to finish.Portland Loop - Half Marathon and Portland Loop - Half Marathon
