This legendary Challenge of the Ossau Valley consists of 5 trail races held from May to September. Come and cheer on the trail runners, or, for the more courageous, register to take part!

Matthieu Ladagnous looks forward to seeing you on 12 July 2026 for the 5th edition of this cycle race! Four routes are available for cyclists, tailored to all levels, taking in the spectacular scenery of the Aspe, Ossau, Ouzom and Lavedan valleys via the legendary passes of Aubisque, Soulor and Hautacam.

The GTVO – or Grand Trail de la Vallée d’Ossau – is the longest trail in Béarn, covering 74 km with 4,600 m of elevation gain. Competitors must complete a full lap of the Ossau Valley, either alone or in teams of two, connecting Marie-Blanque to Aubisque, two famous names in the Tour de France, via the ridges and peaks surrounding the valley. A magnificent, wild and authentic course that winds along narrow mountain trails, 83% of which are single track.

This is the first edition of this mountain triathlon at the Artouste Resort in the village of Fabrèges! Join us on 25 July 2026 to cheer on the triathletes competing in the two categories on offer: S and M. Registration is now open at pyreneeschrono.fr
