Peak 9 – Devils Elbow

Distance: 1.87km ; Elevation Gain: 184 m
 Average Gradient 10%

No part of it is easy, but it’s the first of two hairpins that make it notorious. The gradient on the inside of the bend is estimated to be somewhere in excess of 30%, and while you’d be daft to try riding over that bit, the outside isn’t exactly a piece of cake either.

Peak 5 – Bryn Du

Distance: 3.03km ; Elevation: 256m
Average Gradient 8%

On heading uphill out of Aberdare, riders will be confronted by one of the steepest sections of tarmac they have ever seen. Despite hardly being known outside the Welsh valleys, there aren’t many hills more challenging than Bryn Du in the UK.​

Peak 1- LLangynidr Mountain

Distance: 5.86km ; Elevation Gain: 399m
Average Gradient 7%

Setting off from The Old Station Hub, riders will tackle their first climb of the day – LLangyndir Mountain. Known as the hill of two halves, the LLangyndir Mountain climb begins by meandering through some of the most beautiful pastoral scenes in the Brecon Beacons National Park.
