An alpine pass all for bicycles, from Mezzoldo towards 2,000 meters
About Passo San Marco Bike Day
The Passo San Marco Bike Day: the mountains by bicycle
There is one day in spring when the historic Passo San Marco — the pass that connects Val Brembana to Valtellina at an altitude of 2,000 meters — becomes the exclusive domain of bicycles. This is the Passo San Marco Bike Day, an event that starts from the Municipality of Mezzoldo, in the Province of Bergamo, and attracts cycling enthusiasts and mountain lovers every year.
A safe climb
During the event, the pass is closed to motorized traffic for several hours, from the Mezzoldo side (Val Brembana) to the Albaredo side (Valtellina). This allows cyclists to tackle the climb in complete safety, enjoying the scenery without the worry of cars. The route from Mezzoldo to the summit is approximately 12 km long, with challenging sections and a maximum gradient of 17%.
An event for everyone
The Bike Day is a free, non-competitive event, open to all types of bicycles: it's not about the stopwatch, but the pleasure of cycling in an extraordinary natural setting. There are refreshment points along the route, and at the summit, you'll find refuges, restaurants, and agriturismos to refuel.
History and sustainable tourism
Passo San Marco is no ordinary pass: over the centuries, it marked the ancient border of the Republic of Venice and is crossed by the historic Via Priula. The event, part of the 'Enjoy Stelvio Valtellina' program, was created precisely to enhance this historical and environmental heritage, promoting slow and sustainable tourism that connects Mezzoldo, Val Brembana, and Valtellina.
