I ran my first official race on Saturday (since high school), a 5k with a time of 24:26. Which isn't record breaking but about what I was shooting for. There were 1400 participants and we heard about it on Tuesday.
They had a giant pumpkin and a scarecrow on stilts walking around. I thought people would get trampled at the starting line but everyone was very civil and polite. Your time didn't start until you crossed the starting line so there was no need to be in the very front.
I'm debating doing a half-marathon next.
