My name is Brittany and for my 11th birthday we had a gymathon party :). I thought it would be fun because I am in gymnastics, so what I did was: I cleared out our living room so I wouldn't break anything then when the girls arrived I had my mom speak into a microphone and as thy came in she would announce there names when they came in we started warm ups then when we were ready we started and the fastest one who could do the vault, beam, bars, and floor would win a metal then the winner stays out wile u make a new coarse up and the winner of that one would be the first winner and who ever won that one would get a gold medal and a gift certificate.  PS:when I say vault I mean a place with mattresses and beam u can  use a 2x4 in the backyard but they will need to be running in and out and 4 the bars we used old broom handles and nailed them to trees.  HAVE FUN!!!!!!
