I guess he has a point! Also, I *like* the walk from the staging area to the start line, strangely. It's neat to see the backstage stuff hanging out, and I love the nervous/cold/excited/sleepy energy from the crowd at that point. And seeing people huddling next to gas generators for warmth is always funny. 
(Anyone up for an OKW WISH meet the morning of the marathon so one of you more experienced people could hold my hand while we cross the street?)
The bridge that comes from back stage lane (Epcot employee parking area) across Epcot Center Drive has fireworks on it. This is the same road the runners will be on walking out to the race from the Epcot parking lot. The runners don't come over the bridge they file into the starting corals from the west side of the road. When you are at OKW you are on the East side of the road. You will need to cross over which you can do in the front of the race. The entrance road to Epcot Center Drive from Community Drive puts you right where you want to be 
I have also stayed at Boardwalk & walked to the start line which is about 1 mile. It's a good warm up & you can get up much closer to the start. You can't check anything when you walk to the start. This link will give you a map of Disney roads.

Thanks! I figured must be roads.No secret path, just main roads !! The walk from the finish is much more FUN !! but this is how I manage to sleep to 5 AM when I'm doing the Goofy's. This year will be my 5th also. Go out the front door at BWV over to the Hess Gas station turn left on the sidewalk along Buena Vista Drive. Follow it till you get to your first left (about 1 mile) which is Backstage Ln. You will be merging in with all the runners walking out from the Epcot parking lot on this road. Follow them !! The sidewalk goes away after you pass the firestation on Buena Vista Dr so be careful. The traffic is light at this time but when the lights change a group of cars come at you !! So stay on the grass. Last year I left BWV at 5:30 AM and was in coral with plenty of time at the start. Again, when you walk to the start you miss the staging area and can not check anything. I don't have placed booked yet, not sure where I will be but I try to get OKW because then i get up at 5:30
It's that easy.
