Did the W&D 10k start at MK in 2017? I don't remember.
@Texas84, do you remember?
Both the Dark Side 10k and Half started in MK parking lot, ran to Hollywood Studios, then Epcot.
The Princess Half starts somewhere around Epcot that you have to walk 2 miles to reach the corrals, out to World Drive to the MK gate, around the TTC, back to World Drive, under the water bridge past the Contemporary, through the MK turnstiles , down Main Street, over to Tomorrowland, past Mine Ride & Be Our Guest, through the Castle from the back, over to Splash, cross the train tracks to the Float building (where the Princesses are standing for photos), out the back of MK, down Floridian Way past the Grand Floridian to World Drive to Osceola Parkway to Epcot. But unlike all the other races, you enter Epcot from the front, using the employee only entrance (no World Showcase for this race) to the usual finish line.
If I've misstated the courses, I'm sure
@Texas84,
@dreamfinder or some of the other regulars will correct me.
