Disney Half Marathon

So, Jenny and I signed up to do the Disney Half Marathon again next year! Already looking forward to some warm weather and sunshine in January! Last year we didn't sign up until the end of April (after the NJ Marathon) and when we did it was 65% sold out. We signed up last month for next year b/c we already knew we were going to run it. I just checked the website - it's already sold out! How crazy is that?
