What you’re in for

Run in Brechfa Forest, part of the old Glyn Cothi Forest in Carmarthenshire, this event uses a 13-mile loop following Natural Resources Wales' Wind and Water Trail: one lap for the half marathon, two for the marathon. The ground is mostly forestry track through pine plantation and broadleaf woods with waterfalls and some open views, making it the least technical of the Ridge Runners races. The route is fully marked with marshals and aid stations, and the final cut-off for both distances is 17:00. Parking at Keepers car park is limited, so park in Brechfa village and use the included shuttle bus. Kit is checked at registration, and there are no entries on the day.
