*Loved* the canyon with the tailwind. The last three miles were less fun.
I was glad to be able to exchange my XS shirt for a small (kudos to the race directors (and/or the shirt manufacturers) for having shirt sizes not based on the assumption that people in the race would be bigger than average).
I attribute the 10-minute PR almost entirely to not having to visit a port-a-potty once during the race (first time ever for a half-marathon).
Splits: 7:18, 7:29, 7:30, 7:55, 7:31, 7:34, 7:32, 7:23, 7:38 (thank you, girl in orange shirt, for being so consistent through miles 5-9 and not seeming to mind that I was matching your steps (though maybe you did mind, and you slowed down to lose me)), 8:06, 8:51 (I lost the mental game for a bit here), 7:49, 7:21 (0.1-ish).
