Everesting is the latest fad sweeping the cycling world. The concept is easy – pick any hill, anywhere in the world, and complete repeats of it in a single activity on bike (or on foot or online), until you climb 8,848m – the equivalent height of Mount Everest. Current cycling record holders are two climbing specialists – Spain’s Alberto Contador Velasco (7H 27M) and Britain’s Emma Pooley (completed in 8H 53M).
