The Beast of the Blacks 20 & 40 are new challenges amongst some spectacular, harsh but stimulating trails within the Majestic Black Mountains of Wales. Attracting runners from the elite to the beginner you will not be disappointed by this event. The event will be marked with added support of marshals. Our pledge not to use tape will stand. A generous cut off time of 8 hours will ensure that you can tame the beast. The 40 mile event will be a reverse of the 20 mile loop so what ever you scenery you miss on the first lap you can capture on the second lap.

Starting near the village of Llanbedr deep in the heart of the mountains you will climb directly onto the Black Mountains. Greeted with outstanding views that will follow you around this beautiful route whilst taking in forest trails, mountain tops, river crossings and ancient churches. Red kites will be your companions besides an abundance of wild life. Spring into Spring and enjoy the Mountains at their very best.
