This route consists of a circuit of the Usk Reservoir through the forest. You’ll mostly be riding on hard packed forest roads with a lengthy section on tarmac. The start includes a couple of downhills leading you to the water’s edge, and after the dam there is a road climb to get the legs really working and the heart pumping.
