So much fun! Only rode it up as I didn't have my pads but it was amazing and had to walk a couple sections for sketchiness and a couple due to steepness and tiredness! Great challenge. Mostly black diamond just a couple really janky sections, one with no ride around but easy to walk.
We hope you've been enjoying Trailforks!
