Wow. I'm amazed. So I regularly read your posts and I have questions. So how old or young are you? Why hills? Do you do this for "fun"? Personal challenge? Do you cycle competitively or on a team? I ask because I can't imagine that a typical cyclist would do this. Quite inspiring. I drove to a nature park nearby and there is a sign which says "14% grade" in the distance of less than a mile! Heck, the car struggles to get up it and I can't imagine riding my bike up it!
