Vertical Kilometer Races in Spain 2026

The vertical kilometer is the purest mountain discipline: climb as much as possible in the shortest distance. With courses under 10 km, these races pack 1,000 metres or more of elevation gain into routes that go practically straight to the summit. It is the perfect modality for runners with great climbing power and the ability to manage anaerobic effort. In Spain, the Pyrenees, Picos de Europa and Sierra Nevada offer ideal settings for vertical kilometres with gradients exceeding 30%. You do not need to be an ultramarathoner to enjoy them: their brevity makes them accessible in time, although the intensity is maximal from start to finish.
