Another true Moab classic - Slickrock Trail - not long but intense.
I only made it out to the 'Y' of the trail, after the Porc Rim ride on Wednesday I was simply too cooked and not recovered enough to ride more.
It is my understanding that the basic loop (start out to the Y, one loop around, back) is on the order of 12 miles or so. It'd be a pretty hard working 12 miles though as the climbs up the various areas are quite the thing to experience!
