I put on 100 T-Shirts, which added 50 top heavy pounds to my body and completed a semi altered Decathlon. We could not do pole vault because of our facilities mats and poles having been moved, but instead we used The Mercier Tables http://myweb.lmu.edu/jmureika/track/mercier/index.html to determine how much a triple jump distance would count for in pole vault.
