The Oiz Challenge
The Oiz Challenge is the bicycle touring race that runs through the URDAIBAI Biosphere Reserve. A race that will allow you to enjoy cycling in unique natural surroundings, along the Basque coast and climbing to the top of Bizkaia, with stretches as demanding as they are spectacular.
The Oiz Challenge consists of three different routes: one of 72 km, another of 128 km, and the long-distance route of 164 km.
