I really wish they'd just call it the "Tour of Colorado". Aside from the relative lack of air, this doesn't seem like much of a "challenge". Not a real mountain top finish all week. The prologue TT might be scenic, but there's not a single freakin' turn. Same for the Vail TT, which is an uphill TT, but not very steep.
On the other hand, the final stage covers roads that I ride almost every time I leave my driveway. That's pretty damn cool.
