Ok, I was thinking about the grand loop, but the cripple creek route on this page could be possibilities as well.

These are meant as one day challenges, but could be split up into tours. There are definitely hotels on the grand loop. If this looks good, shoot me a note and I can add more info next week. I'm traveling right now and only have an iPad which is hard to type on.
