I'm planning on doing the Copper Triangle loop on Sept 16 --Start/Finish is the Copper Mtn parking lot, head to Leadville, then to Minturn, and through Vail back to Copper. 78mi, three passes. Fun stuff, and very doable (and popular).
This site has some routes:

But yeah, google the route and just go do it. I'll be happy to Topo routes for ya (I've got DeLorme installed), and heck, I'll go with ya---
