Good luck to your CorbsVWL in the run.
I ran the 1/2 last January and had a very good time. My wife was so excited about my result (maybe she was just shocked I actually finished close to my time goal), that she started talking about doing it herself. I settled the issue by signing both of us up for this coming January 9.
The good part is the course itself. Running through EPCOT as dawn breaks, listening to great music piped through the sound system. Turning up World Drive and heading to the MK. Running through the ticket and transportation center to the applause of the spectators. Entering the MK and turning right up Main Street. Slipping out of the MK by Splash Mountain. Running past the GF and POLY (sadly I was too wiped out to even notice the Poly). Finishing. I've not done the full yet (someday), but I'm sure there is great stuff on the last 1/2 of the course as well.
And for all you walkers, enjoy yourself and feel good about reaching your goal. Do the runners a favor, however, and start in the back. Ideally a big run falls out at the start, as the rabbits are in front, the "middle of the packers" like me are in the middle, and the walkers are in the back. Unfortunately too many participants start near the front, in spite of their planned 14 minute per mile pace, which can be extremely dangerous when the mob surges forward.
We stayed at the BWI last year and are now BWV members for the coming race. Getting to the staging area in the EPCOT parking lot, however, is a pain. They say the busses start running early, and quit running early, so I went to plan b. I woke up at 4:30, stretched, etc., then walked out of the BWI lobby at 5:10. There is no direct route from the EPCOT resorts to the EPCOT parking lot, so I'd planned to walk behind EPCOT and turn left up towards the start area and find my way there. A WDW bus stopped and the driver told me she was headed to the staging area, and offered the ride. I happily took at, and got to the staging area about 5:40, which was plenty of time to get to the start.
The funny thing was many people seemed to have also come up with "alternative" means to the staging area, as at 5:40 there were a mass of people walking quickly towards the start. A few runners came from the Port Orleans resort area, and they seemed to have a very short route, just walking a few steps from their resort to the start.
If anyove has better hints at getting to the start, I'd love to hear them.
The finish to the 1/2 is in the MK parking lot, just in front of the Poly. I know they provide bus transport back to the resorts, but I don't know how that works out. I'm sure someone else can help you.
Anyway, enjoy your training. I really enjoyed the run last year, and I'm sure you will as well.
