The Epona 100 mile ultra is a stunningly beautiful but challenging course, weaving its way through the iconic Bannau Brycheiniog (Brecon Beacons) National Park. You'll tackle a formidable 5,181m of elevation as you traverse a trio of legendary trails: the historic Offa's Dyke Path, the rugged Cambrian Way, and the glorious Beacons Way.
