South West Coast 50

Beginning at the impressive Dunster Castle, take on 10-50km to raise funds for St Mungo’s

About the event

The South West Ultra Challenge 2026 is not just a stunning summer adventure—it’s a chance to make a real difference by fundraising for St Mungo’s. Starting from the basecamp beneath Dunster Castle, the 50km loop takes in the dramatic coastline from Minehead and the rugged beauty of Exmoor, with over 1,600 metres of climb and unforgettable views.

Whether you take on the full 50km, a 25km stretch, or the family-friendly 10km, every step helps support people experiencing homelessness. By fundraising for St Mungo’s, you’ll be helping to provide accommodation and vital support services, forming a pathway to recovery for the people we support.
