The Côte de Greenhow Hill, at nearly 4Km/2.5 miles, is the Tour de Yorkshire's longest climb and is a tough test of the riders' legs coming late in the final Stage 4 of the race. Official climbs #52. There are three really steep sections with flatter sections in between, before the final climb tops out with stunning views of the Nidderdale valley.
Follow the Stage 4 route as it turns south towards Otley, then take in a tour of the Thruscross reservoir, looping back towards Pateley Bridge with a long climb onto the moors at Heyshaw, finishing with a fast, winding descent back to the finish at Glasshouses.
