Transpyrenees

Transpyrenees is an unsupported, non-stop road cycling challenge organised by Transibérica Ultracycling. The route crosses the Pyrenees from the Atlantic coast to the Mediterranean, taking riders over some of the mountain range’s most iconic climbs.

The 2027 edition starts in San Sebastián and covers approximately 1,124 km with 27,500 metres of elevation gain. Along the way, riders tackle 34 mountain passes, including the Col d’Aubisque, Col du Tourmalet, Col d’Aspin and Col de Peyresourde. The highest point is the Col de Tramassel at 1,630 metres.

Around half of the route runs through Spain, with the remainder crossing the French side of the Pyrenees. Although primarily a road event, the course includes two short gravel sections totalling approximately seven kilometres. A road bike with wider tyres is recommended.

Transpyrenees follows a single-stage format: the clock runs continuously from the start to the finish, including time spent eating, resting or sleeping. Riders must manage their own food, accommodation, navigation and mechanical issues, without outside assistance. Participants can enter solo or as a pair.

There is a final classification, but no prize for the fastest rider. The main achievement is completing this demanding crossing of the Pyrenees within the seven-day time limit.
