Welsh 3 Peaks Race

Llanberis, United Kingdom • 21 Sep 2026

Welsh 3 Peaks Race

The Welsh 3 Peaks Race is a multi day continuous mountain race covering 286 km with over 11,000 metres of ascent. Entrants may compete as a SOLO runner or as part of a TEAM of three or six people.

The route sets off from Llanberis, passes the summit of Yr Wyddfa early, continues through Moelwyn, the Rhinog and Mawddach areas to Cadair Idris, then traverses Tarrens, Pumlumon, the Radnorshire Hills and the Cambrian Mountains to Bannau Brecheiniog and Pen y Fan, finishing at Storey Arms. Competitors largely follow the Cambrian Way on sections of the route.

Event logistics include a headquarters at Llanderis, Y Ganolfan (LL55 4UR). The race is fully tracked, timed and monitored and provides five indoor rest areas with toilets, first aid, food, drinks, masseurs and sleeping areas, plus five outdoor support stations with water and provisions. The event lists 25 Mountain Leaders and is limited to 150 participants. The published time limit is 4.5 days (108 hours), which equates to an average overall speed requirement of about 1.7 mph.

Participants must be comfortable in mountain and remote environments and largely self sufficient. Teams follow strict rules: each team member completes one specific section and changeovers occur at event checkpoints. Team kit requirements match those for solo competitors.
