Sid Valley Ring Half Marathon

The Sid Valley Ring Half Marathon is an annual running event held in the scenic Sid Valley area of Devon, England. The 22km course follows the Sid Valley Ring walking route, featuring an uphill start through quiet country lanes and footpaths, climbing to 236m before descending into picturesque villages like Sidbury and Harcombe. Runners experience stunning coastal views across Lyme Bay from Dunscombe cliffs and traverse woodland and coastal paths before finishing in Sidmouth.

In 2026, a new Third Marathon (13.5km) option is introduced, joining the half marathon route near Harcombe. The event offers marked courses, aid stations, first aid, and a unique oak coaster finisher’s medal, welcoming both runners and walkers.
