Do they ever! The WDW and Princess half marathons run through Epcot and MK, while the WDW full marathon runs through all 4 parks! The newest event, Disney's Wine and Dine half marathon will most likely be run from the ESPN Wide World of Sports to AK, MGM(DHS), and finish at Epcot!

I am now a race snob, and will only run Disney races!

If you have anymore questions, feel free to ask. I have run the full marathon once, the Princess twice, and the Disneyland Half once (registered for it again this year!).
