Registration for the 2013 Walt Disney World Half Marathon opened today, and you bet I signed up again! It'll be my 14th half in 14 months (one more month and race than I planned but I'll just call it my "bonus" race).
I'd encourage anybody who is on the fence about it to absolutely sign up. I know its a lot of money, but its Disney - they do it right. And it gives you something to look forward to (and train for!).
