Starting at the base of Stony Street, the course takes a sharp turn onto Catherine Hill, climbing 179 yards before ending where the cobbles give way at the hill’s summit. Flanked by 17th-century buildings and incredibly narrow, the route is as breathtaking to behold as it is challenging to ride. With thousands of cobbles, a shifting gradient, and that tight corner to navigate, the Cobble Wobble course is a true test of both strength and skill.
