Oh man I need to update! Life has been so busy lately. After the 5k, I rested for a couple days, then went on a couple shorter runs with everyone. It was so hot! I don't do well running in the heat, but I suppose it's something I'll get better at.
My nike+ system just told me I've reached Orange level now! that means I've run more than 30 miles since I got the arm band. Woo!
I'll post a more comprehensive update later...right now I'm battling a bit of a cold or something and am rather fuzzy headed.
