TTFs on TrailWallride
Boost can be ridden both ways. The most popular direction is downhill, transitioning from Bottom Clencher. It is the most fun descent from the top of Sugarloaf.The is one wallride and one tree puzzle, both about in the middle. The trail overall is narrow (18 inch tread) with a very steep sideslope which adds just a little bit of pucker to the experience. As a climb, Boost will test your ability, as there are intermittent short-but-steep burst climbs that will test your ability to Boost your energy output. See if you can make it all the way up without dropping a heel or walking.

This trail has potential to be great. Just need some widening. Riding downhill of course. Happy to volunteer

Hard to ride uphill, trail is super narrow and kept falling off downslope. Grades are never too steep thankfully
We hope you've been enjoying Trailforks!
