Extreme Elevation Gain Trail Races in Spain 2026

Extreme elevation gain races exceed 4,000 metres of positive gain and represent the elite of mountain trail running. These are events reserved for experienced runners with years of preparation, where the mountain sets the rules: endless climbs, quad-destroying descents, exposure to changing weather conditions and the need to manage your body for many hours in hostile terrain. In Spain, these elevation gains are reached in the great Pyrenean ultras, complete range traverses and extreme skyrunning races. Every metre of positive gain means a metre of descent, and it is on the downhill where the race is won or lost. These are transformative experiences that require absolute respect for the mountain, meticulous planning and the humility of knowing that finishing is already a triumph.
