About the race
Sid Valley Ring Half Marathon, hosted by Climb South West, follows the Sid Valley Ring walking route in East Devon. The Half Marathon is an uphill-start loop through quiet lanes, footpaths and coastal scenery, climbing to 236m before descending to Sidbury, Harcombe, and the coast path with views over Lyme Bay to Portland and Berry Head, then inland to Salcombe Regis and back to Sidmouth. In 2026 a new Sid Valley Ring Third Marathon (about 13.5 km) joins the route upstream before reconvening with the Half route.
The event is fully marked, with aid stations, first aid, mud and hills, and finishers receive a solid oak coaster; open to runners and walkers. Proceeds support trail maintenance. Visit the organization's website for the most recent information.
