Actually it was kinda miserable. About 50 degrees, but with a light--very cold--wind, and as you can see in the picture, a heavy drizzle that turned into a light rain at the end of the race.
I had a blast! It was truly a lot of fun! Spent some time with a friend, and beat my best time ever for this distance by over 3 minutes! To be fair, this is the first organized run I've ever done, and there's something about it that pushes you to run just a little faster than you otherwise would.
Next goal: a 10k.
