The weather on race day was sunny, windy, and according to the spectators was cold (seemed hot to me). Having to do two laps of most of the course was not as bad as I thought it might be, but I think I would still prefer to run a single loop just because it feels like you've acheived more if you get 6 miles from where you started.
I'm also wondering about whether I want to enter any other races, or perhaps take up something new...
