Had I known then that that would be my last swim for at least 6 months, I would have freaked the fuck out.
As it is, I'm resigned. I have used the walk around the block and will continue it, but I finally bit the bullet this afternoon and set up the treadmill. It folds down into a lovely bench so I've left it in bench mode now for too long. Knowing me, I'm going to have to impose some kind of regime but for now, I'm just going to let it guilt me into walking in the afternoons.
