Two weeks out from my trip and I was afraid this was the case. Any recommendations for other running trails at Wilderness Lodge or Ft Wilderness?
You can run around the latter all you want; however, getting there has become an issue since you can only take a bus there now unless you drive over and have a reservation for dining there. That's rather a pain. At the Lodge itself, you can piece together routes to give you some options. (A) You can start at Geyser Point and take the path that takes you by all the cabins. You can run down one side, turn around, and run down to the opposite side--passing by GP--then come back to GP. (B) Alternately, you can start at one end of the path and run all the way down to the other end, then retrace your steps. (C) The New Balance running sign now has a route that has you start at that sign, run down to the farthest cabin on the south side (8026), cross over toward the cabin parking lot, then take the new sidewalk that was put down beside the old VWL building during the cabin construction and head back to the sign. (D) Finally, I've suggested taking the cabin path, running through the cabin parking lot (either end), hooking up to the main drive via said parking lot, then turning toward the back of the main parking lot out in front of WL proper and follow it around to the other cabin parking lot and back to your starting point.
Route A: a touch under a mile
Route B: same
Route C: just under half a mile
Route D: unsure, but I'd guess one loop would be right at a mile, perhaps a bit more
Obviously, you could mix and match or repeat loops to get the mileage you want. It's not optimum for running but beats driving to FW or a treadmill.
