Starting from race headquarters in Talybont-on-Usk, you will head out to the western extreme of the course, the Black Mountain, traversing along the way some spectacular ridgelines, tackling some torrid climbs and passing over 2 of the 10 highest peaks (Fan Fawr and Fan Llia). There will be 3 feed stations along this section of the course that will help prepare you for the tough long ascent of Fan Brycheiniog and then Bannau Sir Gaer, at the furthest point west on the course. From here you will be able to look east and see just how far you have travelled (and how far you still have to go!). You will then begin your return journey following a more northerly route back to Talybont, which although shorter than the first half, will seem a lot tougher. There are only 2 feed stations on the way back and 6 peaks still to bag. Some very painful climbs on tired legs will see you across the most stunning and dramatic looking landscape in South Wales. This will include the highest and most iconic mountain in the south of Britain, Pen y Fan. From the top of that famous red sandstone ridge you will be able to look east and west (on a clear day) to gain a real perspective of just how far the course takes you and how amazing the Brecon Beacons really are. A couple more peaks to go before you see the familiar sight of Craig Pwllfa, the first ridgeline that you climbed to some 20 hours or so earlier. A pleasant run downhill to Talybont Reservoir and a short flat trail section is all that now stands between you and the finish of what will undoubtedly be one of the toughest challenges you will have faced.

There is a short trail section at the start, to insure that competitors are spread out in a long line before hitting the open hillside.
