Amazing climb starting at Bormio from Stelvio eXperience Bicycle Cafe. Down the valley via Grosio till Mazzo where the climb starts. 10.5% is the average gradient of the climb for 11,9 kms. The first 7 kms have several stretches of 18-19% of max gradient! At turn 8 there is a junction for the descent to Grosio and at turn 7 you can find the last part of the hardest side of mortirolo (Tiolo start). The last 5 bends are more gentle and gradual and prepare your mind and body ready to scream: I DID IT!
