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.

The Race to the Sky is an annual automobile and motorcycle gravel hillclimb to the summit of a mountain in the Cardrona Valley of New Zealand. The race was held every year from 1998 to 2007 for two days over the Easter weekend as the Silverstone Race to the Sky, and returned in 2015 as the Repco Race to the Sky.
