Combining sections of cancelled Y 100 Sir Fynwy (2020 & 21) & some of the Valleys 100 route (2014) this event will take entrants into the heart of the Black Mountains to Cwmyoy & Llanthony. Climbing over Loxidge Tump, entrants will visit Longtown, Pandy & Skirrid before returning to the Walk HQ at Abergavenny. The second section will see entrants enter the UNESCO World Heritage site of Blaenavon & the forgotten landscape to Coity Mountain, Cwmavon & a finish along the Monmouthshire & Brecon canal. This is a mountainous route and entrants should be suitably prepared for the challenge that awaits
