About
The Epona 100 is a legendary ultramarathon held on 8 May 2027 from Llanfoist, across the rugged terrain of Bannau Brycheiniog (the Brecon Beacons) and the Black Mountains in South Wales. Runners choose between a demanding 100-mile course, starting at 06:00, and a 100 km (62-mile) option, the shorter distance offering a stimulating step for those preparing for the full ultra experience.
The event is designed to push the limits of physical endurance and mental resilience. The course is a single epic loop linking three renowned Welsh trails, Offa's Dyke Path, the Cambrian Way and the Beacons Way, for a relentless test through some of the UK's most iconic and unforgiving landscapes.
