One of the first people I met at my job while living in Pittsburgh was Julie. She was also from Wisconsin, so we swapped stories about how "The Pitts" differed from back home. Julie and her now-husband-then-fiance Matt were both marathon runners. I was always in awe of their athleticism.
She moved back to Wisconsin a couple of years ago, but Julie continues to be a source of amazement. Last month, she and Matt finished the Ironman Wisconsin. I read her blog when I don't feel like going to the gym.
Prepare to be inspired.
