The One Hundred® Black Mountains will be hosted in the Black Mountains, in south Wales. Athletes will have 36 hours to tame these hills.

This race includes four different distances, among which are the 100 miles and 100km part of the One Hundred® World Series.

This event is bound to be successful thanks to the organisers' expertise and know-how, the live streaming to an audience of thousands, and the participation of elite athletes from all over the world.
