That's very true. I am trying to recollect what really happened to my hill climbing experience today now. There are ups and downs along to whole climb. And the very steep uphill is about 18% grade. I did 17% and failed because I had no more air in me

I think I would have to be in very good shape or even the top of my shape to be able to make it with the same bike carrying the same load
