My wife and I work out regularly. Truth be told she is a mutant and I just try to not look like her Dad on the beach!

This past January we did not work out on the trip and have sworn that will never happen again.

That being said we did have to walk the hill you referenced and even in decent shape that incline can be quite the challenge. I run two 8:15 minute miles every other day and that hill was still a pain in the _ss! Can't imagine having to walk it while completely out of shape. I would be all sweaty when I got to my destination.
