When you have nothing left, thats when u have to push yourself the hardest. gettin through the hard part is what makes u bigger, stronger, faster. I will need the motivation of this site at Rebel Race. I just signed up at www.rebelrace.com …can’t wait to run the 5k through military style obstacles and crawl in the mud! My girlfriend’s crazier than I am- she’s doing the 15k! This will be an awesome hardcore workout…muscle confusion and cardio at the same time! I already started training. Is anybody else going to the race?
