I think the difficulty of this loop should be upgraded, to reflect the harder sections, where beginners get injured (exposed singletrack... where the hill drops off). They also block flow on the singletrack, and would be better off on wider trails, such as Arastradero.

We hope you've been enjoying Trailforks!
