As you likely know, Crazylegs is a massive fundraiser for the UW Athletic Department that attracts thousands of runners and walker of all abilities. I ran it from 2008-2011. The band, cheerleaders, and some UW athletes would show up and greet you at the starting line. Back then, the 8K route started at the Capitol square and headed up Wisconsin Ave to Langdon. The brutal middle two miles were up and down the hills of Observatory drive. The race snaked past the McClimon Track/Soccer stadium and ended with a final sprint to the finish line at midfield of Camp Randall. I would then throw up in a trash can and eat some fruit slices.
I set my PR in 2009 amidst sporadic downpours. It was a great race and fun environment.
