I hadn't thought of extra sets of clothes, I wonder if he has. He's doing relay so he will have some time between laps and want to be out of the chamois and a clean set is always nice. I'm still struggling on the food a bit. He has camp stoves but they are somewhere in the depths of his parent's garage so we are trying to decide if we want to do without. I'm going to consult the Feedzoone book today to see if I can get any brilliant ideas from there.
