OUR FAVORITE UK HILL CLIMB
This is a magnificent bucket list climb for all cyclists, not just British citizens. This is our favorite of Simon Warren’s 100 Greatest Cycling Climbs. Hardknott Pass is a 10/10 in Simon Warren’s book and while that means it’s difficulty is 10 on a scale of 10, it could be a 10 for challenge and a 10 also for scenery. This ride is simply an amazing experience.
