Zero-3000 Extreme Racewww.zerotremila.com/en/

The only race in the world that combines two endurance sports like cycling and ski mountaineering will cover some of the most unique territory in the world: from the rolling hills of Asolo, a town rich in art and history, to the highest peak of the Marmolada, Queen of the Dolomites at 3343 m. above sea level.
This is a true test for men and women of steel. The goal? Cover 3715 m of altitude change in the least time possible, 1900 metres distributed over 124 km by bicycle and another 1800 m with skis on a climb of about 12 km.
