Ran my first 10K this morning, and did much better than I expected. Originally I thought I could do under an hour, and then I tried running 6.2 by myself last Monday and couldn't even finish without stopping to walk a few times during the last couple miles. But I finished in 57:15 and didn't have to stop to walk at all, so I was very happy with that.
I was a little worried about running so early in the morning - race started at 6:30 and I'm used to mid-afternoon runs, but the time didn't have any sort of negative affect at all. It was cold though, well cold for Florida at least - 47 degrees at the time the race started!
