Hi Jessica,
I was lucky enough to be at Disney World this year for the Princess half marathon weekend with a number of my Mom Panelist best friends. While I have to admit I was a cheerleading, and not a runner for this years' event, it was such an amazing and inspirational weekend, that I look forward to returning next year.
Now having said that, there has been no official announcement that the event will be held next year but given its popularity, I would certainly expect to see it return in 2011 and hopefully many more years in the future. The best place to check for announcements on the Princess marathon weekend as well as the other numerous races at Disney World, visit
Disney World ESPN's Wide World of Sports. Once announced, you will be able to find out all event information, costs as well as register for the race, on the website.
On a side note, there are a few great races still on the calendar this year. Information on these events can also be found
here.
Hope to see you there next year!
