be careful. Hold everyone harmless and watch out for trees, roots, rocks, mud, and other hidden objects all play havoc with you.

Park at Probike&Run or at Golf course. Get in right before #9 tee box. Nice Ride but watch out for hikers and other riders. Its about 2.5 hour ride. BPH will average 150 so its a nice work out. Approximately 2000ft ascent and 2000ft descent. Expect to burn 1000 calories.

Fun XC trail with a few downhill sections. Connect it to Pfundstein for more downhill. Also, if you're not into climbing, I recommend parking at the water tower lot up the road from the start- you can easily hop on the trail at a high point as it parallels the road in that area. Make it a loop by jumping on the red trail (otherside of the road) and riding back.

As of 10/20/20- lots of leaf cover but still good riding.

Trail Kotobuki
Berms have been added/redone on the section before the road crossing. Fast and flowy!

One of the most unrewarding trails I’ve ever ridden in my life. It’s pretty rare to feel like you are pedaling uphill for an entire ride, but this trail accomplishes that very perception. Whoever built this trail hated going downhill. Would not recommend this to anyone that enjoys descending.

It was pouring as I rode this, generally trail is good condition with lots of hard pack so the rain isn’t causing mud, but there were a few washouts in the trail from the heavy rain
