I lived through the WDW Marathon entry fee discount for the medal release without signing up for the race! Whew!! LOL
Actually, if finances weren't an issue, I think I would go for it and just do a slow walk/run like I did for the Goofy this past year. That medal is just amazing, and the course changes to run through the speedway and the baseball stadium make it that much more appealing!! I think I could manage that without hurting myself. It wouldn't be fast but that doesn't matter to me.
Alas, the money is just not there right now. And that's OK. I'm still hoping for Princess 2013.
