Heh. I've always been a bit of a tenderfoot, but then again, I grew up in the city, where you didn't walk barefoot anywhere outside your house. Gravel just sounds like a way to give yourself cuts on your feet!

On the other hand, my exercise class includes the instruction to take off your shoes and socks, in order to get better foot function with your toes - so maybe there's some of that going on there as well.

I think I may have to check out this challenge anyway....
