7) Post race clothing – what are you going to wear after the run?  It is a good idea to pack a little something to put on.  A long sleeve shirt, some pants or your favorite sandals maybe have someone at the end to help you get changed (preferably someone you know).  It feels great to finish your event but it feels even better to get out of those wet, sweat encrusted, smelly running clothes and put on something nice and dry.  And warm.  After you do an endurance event your immune system drops for a while.  Give your immune system a hand by getting yourself warm and something to eat post event.
