down or walk for a bit, take long breaths, and place a hand on the area that is sore.
have a positive mind set – there may be points in the race when you feel its too hard, prepare yourself with positive thoughts and self-talk to help you get through it. for example: “i am, i can, i will” and “breathe, believe, achieve”.
try to buddy up for the run leg and help keep each other going.
most of all – enjoy the moment and have fun!
