Running my 1st 5K tomorrow

It is suppose to be low 30's overnight and we are running @9a.m. It could be raining/snowing mix! What have I gotten myself into???? I'm definitly not in it to win it, just to finish would be an accomplishment! We will work on our times for the 5K in August we are running! Can't wait but still really nervous. I feel those butterflies starting to swarm faster in my stomach and the time gets closer. I keep telling myself the only one I have to answer to is myself! I know I can do IT!!!!!
