Cycling Passo Mortirolo from Tovo - it’s a very hard climb!
Ride 12.2 kilometers gaining 1277 meters at 10.5% average grade.
This is another route up Mortirolo that is best done with at least a 30t cassette as it averages 10.5% for 12.2 km. While this climb presents a great cycling challenge, it is the least scenic of the climbs - for much of the route we are bordered by thick forest which blocks our view of all but the roadway ahead - on a climb that registers a 10.5% as an average grade, perhaps just the road in below and directly in front is all we need . . .
12.2 km / 1,285 m / 10.5%
