Rated aMTB3 - Support Required

This route is intended for adaptive riders, but anyone can do it. It skips the first section of trail which is exposed with off-camber and not suitable for adaptive. The trail itself has plenty of sidehill and will require assistance. Bring a support rider....or two It isn't so much work that it's not worth it. Be ready for the rock roll at the end. Some riders may require a spotter. Read TRAIL BLOG linked below for more info, video, and pictures.
