From the carpark head up the road just before the quarry and take a right turn over the bridge. Avoid the right turn, this is where you will return from and run up the road about 500 meters until you get to the Involution track on the left. Run up the track to the top, take note there may be mountain bikers riding down. At the top is a small clearing with several tracks off, take the Widdershins track. Follow this track down and take in the amazing views to another clearing. You will now see a much wider track through some trees, this is the Barnicoat track. Run down this to the bottom to complete the loop. About 500 meters into the Barnicoat track you will see a left turn, take this short detour to a grassy field at the top for spectacular 360 degree views.
