13-year Old Completes Ultra-Marathon (50 miles)

Looking at http://www.runnersworld.com/ last night, I came across Mackenzie's story. This 13-year old, the daughter of a runner, had already run 26.2, a full marathon, when she decided to try an ultra marathon of 50 MILES. By the way, no one thought she'd be able to finish the marathon, which she did. The video at this link takes you through the ultra marathon with her. http://www.runnersworld.com/video/index.html?bcpid=717784762&bclid=1126074425/&bctid=1349141442

It's amazing what a person can do when she puts her mind to it. I'm not condoning 13-year-olds performing such strenuous feats, but I have to just say WOW.

It makes 13.1 in April seem somehow more possible for me.
