Join us for the BOWUM – The Borderlands of Wales Ultra Marathon, an unforgettable journey through the heart of Monmouthshire. Covering 30 miles of raw Welsh beauty, this ultra marathon explores the legendary Three Castles Walk, connecting the historic fortresses of Skenfrith, Grosmont, and White Castle.
This is more than just a race – it’s an adventure through the ancient borderlands where Wales meets England, weaving through rolling hills, hidden valleys, and timeless villages. Whether you’re chasing a personal best or soaking in the scenery, Pegasus invites you to discover the soul of the Welsh Marches.
Experience the spirit of Wales, its rugged landscapes, deep history, and unmatched natural beauty – all in one epic day on foot.
