Reservoir to reservoir. Hell of a ride. Uphill THE WHOLE WAY to almost 500m from 200m in 2 miles. I almost chundered doing it this aft but I'm not "hill fit" at mo. Descent awesome if not for the drainage (?) columns which slow you down/jerk the spine! Clag in today so gonna have to do it again to get the views. I hear this is a time trial route now - anyone shed light?
