I spent the entire summer sitting on my bum at sea level.

Of course, I was paddling my way around a beautiful island in the wilderness, but that’s beside the point. Right now my legs and butt don’t give a hoot what my arms, shoulders and back have been doing. They’re screaming mad because I’m back up at 6,500 feet and running. And mountain biking. And doing squats in the gym.

This is causing shock to my poor legs, which got used to thinking, “Hey, finally she’s giving us a break!” Well, your break is over, dear legs. Oh, and lungs, you’ve got to be more efficient again, too. You know the drill. You’ll be thanking me soon enough.
