Today I ran with the runners at work over lunch, their four-mile route. I was ready to walk when as we approached--I hoped--the turn-around point. I puffed, "People, I'm walking," and Tale said the turn-around was just ahead and they'd join me on the way back but someone else encouraged, "You can do it!" so I did it, trotting up to that point. Then I did walk a bit, started running again, caught up after about a half mile (they slowed, and Tale turned back for me), and kept kind of up until the last half mile. I need a new bra.
