Your not the only one who finds the RR to be a little mundane, RR is all about the canyon views and flat easy riding. The AZT section was one of the first pieces of trail built just to be the AZT back then they were using FS fire crews to do the trail work. They didn't go out of the way to keep the grades down but rather pushed the trail through to get you where you are going in a shorter rather then longer way. To build the AZT at the same grades as RR it would be a lot longer. Pretty sure the guy who did the RR used a Sweco trail machine with the goal in mind of building a really easy trail. For an experienced rider it is not at all challenging. Like the Canelo hills section of the AZT the fire crews did not go out of their way to create an easy bike trail with out really trying they built a more challenging trail that is more interesting if you have the skills and stamina to ride it not that its that hard either just more interesting. IMHO
