Disney Half Marathon Weekend not on Crowd Calendar?

We just booked our WDW trip Feb 21-28 2015. I planned it with the crowd calendar in mind. I was surprised to see that the Disney Princess Half Marathon was not on the calendar. How is this event going to effect our trip? Should I reschedule?


Check out http://touringplans.com/walt-disney-world/crowd-levels - that is where the TP folk discuss the impact of various events and holidays on WDW crowds.

Although they do not discuss any of the lesser running events, they do talk about Disney Marathon Weekend. Based on what they say, I would not rebook, but just be prepared for some traffic delays on race mornings.
