Aw bummer! Happy birthday though! I don't think it will be a complete wash out this afternoon/evening, and at least it'll keep the crowds low!
As for the race this morning, ugh what a beast! Not my best by a long shot. You'd think after training for years in central Florida humidity, I'd be used to it. Far from it! The crazy winds that have been around for weeks (even up until last night) seemed to completely vanish. The stagnant, humid air, coupled with a course that never thinned out, equaled one of my worst race experiences. Once I saw my 15K time, I knew I wasn't going to hit the time goal I wanted, and I certainly didn't want to make myself sick and push too much.
I was in F (F3 I think), and I'm used to being in the backish part of the pack, but I feel I spent a lot of wasted effort weaving around others. At most of the water stops, people would crowd the first person handing out PowerAde, coming to a complete stop.
I liked the course being different, but it never seemed to give people a chance to spread out. My running app recorded me at 13.8, which i believe is the highest distance I've recorded on a runDisney course.
Anyway, enough of my ranting. I hope everyone had a better experience than me! Wasn't my race this time, but there's always another one. And since I'm a glutton for punishment, I'm sure I'll be signing up for next year's Dark Side Half as well...
