The crown jewel of TMP. Either direction has a sick dh section. Go south if you want a super fast and loose dh, go north if you want the tech. The middle has all the fun tech problems that you can totally clear with some practice.

Good challenge in both directions. Techy and rewarding if cleaned.

Did this east to west from mockingbird to star pass. Some slower tech in there but nice views. No real pay off for the effort. Next time will ride it west to east and see how that fares.
We hope you've been enjoying Trailforks!
