The Pikes Peak International Hill Climb (PPIHC), also known as The Race to the Clouds, is an annual automobile hillclimb to the summit of Pikes Peak in Colorado, USA. The track measures 12.42 miles (19.99 km) and has over 156 turns, climbing 4,720 ft (1,440 m) from the start at Mile 7 on Pikes Peak Highway, to the finish at 14,115 ft (4,302 m), on grades averaging 7.2%. It used to consist of both gravel and paved sections, but as of August 2011, the highway is fully paved; as a result, all subsequent events will be run on asphalt from start to finish.

Hillclimbing, also known as hill climbing, speed hillclimbing, or speed hill climbing, is a branch of motorsport in which drivers compete against the clock to complete an uphill course. It is one of the oldest forms of motorsport, since the first known hillclimb at La Turbie near Nice, France, took place as long ago as 31 January 1897. The hillclimb held at Shelsley Walsh, in Worcestershire, England, is the world's oldest continuously staged motorsport event still staged on its original course, having been first run in 1905.
