The fourth stage of the 2026 WMRA Mountain Running World Cup kicked off on Thursday evening as competitors gathered on the island of La Palma for the Uphill race at Transvulcania, the latest instalment of the competition on one of the sport's most demanding but most beautiful circuits.

La Palma, widely regarded as the steepest island in the world, provided an uncompromising backdrop for the competition. A high-calibre elite field took to the start line in the Port of Tazacorte for a 7.3-kilometre course demanding 1,200 metres of vertical ascent.
