Start: Parking at the entrance to Arantza (272 m). It’s a 28 km route, hard but beautiful. Most of the route goes by track, sometimes it’s concrete and other times loose stone.

The first kilometers are uphill, but then there is a long stone track that descends to Berrizaun. There, we will take the old train track towards Lesaka, it’s a very smooth ride.

After going through the town of Lesaka, we will take a track that goes to Itsaszelaieta (500 m), it’s a long climb. From there, we will go down to the river of Arrata (150 m), where we will have a 1.5 km ascent before reaching the starting point.
