The next running of this challenge event will take place on October 5th. 2024. The race distance will be approximately 50 km (31.5 miles) with a total ascent and descent of about 5,200ft (1585m). Most of the race will be off road with some short road sections including the hellishly steep ascent (25%) of the iconic Devil's staircase. The race will test endurance and stamina but will reward the runner with a fantastic, lasting and memorable experience.

The race will start in the centre of Llanwrtyd at 09:00 and finish in the same place. The route will be on a mixture of tarmac road, forest tracks and farmland.

The course will be marshalled and waymarked with water points and two feed stations providing cold and hot drinks, bananas, biscuits and sweets. At the finish there will be Welsh cawl and a vegetarian alternative on offer. Each runner will receive a unique devil medal and there will be prizes for the first three male and female runners. The entry fee is £45.
