Gran Fondo BIBE Transbizkaia
Starting and finishing at Landako Gunea, Durango, the Gran Fondo BIBE Transbizkaia has earned a reputation in just a few editions as one of the toughest cyclosportives in northern Spain. Its 9th edition keeps the non-competitive format but with a profile that demands serious preparation: nearly 180 km and 3,500 m of accumulated elevation gain over some of Bizkaia’s most demanding climbs.
A 180-kilometer route through Bizkaia’s climbs
The route strings together several of the territory’s best-known climbs, combining valley stretches with long ascents that test both fitness and pacing. This is not an event for beginners: its elevation profile alone puts it among Spain’s most demanding gran fondos.
An event built for experienced cyclists
Unlike other rides aimed at a broader audience, the BIBE Transbizkaia attracts riders with previous experience in long-distance, mountainous events. The name “Transbizkaia” sums up its purpose well: crossing the territory end to end through its most mountainous areas.
Durango beyond the ride
Durango, in the heart of the Duranguesado, is a gateway to some of Bizkaia’s best-known mountain landscapes, along with a well-preserved historic center. Discover more events in the region in Basque Country.
