I wish I could be of help! I'm in Seattle but don't do those longer type runs yet. I'll ask DH later today though, maybe he has some ideas. He doesn't run at all but he hikes and I know there are some beautiful trails around.
Good deal with the MarriottSince I work for an airline (flight benefits) I always wished a family member worked for a hotel chain. I was trying to work out a trade system with a Fairmont employee once but alas, it didn't come to fruition.
