The trail itself is a blue, but there is many gap jumps of various sizes making the trail a black diamond if you're hitting the jumps. Ride arounds for all features.
A horse trail crosses Thornstar. Please make noise at the crossing and yield to horses.

More of a blue than a black to be honest. But amazing ride
TwkdMTB
Trail was running really well today. Recent work on it feels good.

Builders have just freshly worked on it, keep an eye out as they might still be tuning! For those that haven't hit this before its an amazing growth trail, hitting the ride arounds makes this an easier ride than OSR, but clearing that rock gap is probably a harder jump than anything on Rip N' Dip if you want to hit it! Get out there ease your way into clearing it all
We hope you've been enjoying Trailforks!
