The LDWA’s toughest mountain event is back – now with a new 20-mile route option that also explores the Black Mountains. Tackle sections of the cancelled Y 100 Sir Fynwy and the classic Valleys 100 route.
Expect epic climbs through the Black Mountains such as Deri, Loxidge Tump and Skirrid via Cwmyoy, Llanthony and Pandy.
Then venture into Blaenavon’s World Heritage landscape, Coity Mountain, and finish along the Monmouthshire & Brecon canal.
Only for the fittest. Are you ready?
