About Passo del Mortirolo

The Mortirolo (1852 m) is one of the hardest climbs in Europe: from Mazzo di Valtellina a narrow road climbs at over 10 % on average. A monument recalls Marco Pantani, who made history here in 1994.

In rampida you ride the route exactly as it lies on the road: the gradient reaches your trainer metre by metre, the scenery is built from real elevation data and OpenStreetMap. A pacer group can pull you along, and next time you race your own ghost.
