We are thrilled to announce that the Grasshopper Adventure Series is returning to the Jackson State Demonstration Forest in Casper, California. The 25.5 mi. loop includes 9.5 mi. of flowing single track and the remainder is composed of dirt and gravel roads. 100% off-road racing and riding! Long Course riders will do two laps for a total of 51 miles, and the Short Course will ride one lap.

The Jackson Forest Hopper starts in Caspar, CA and heads straight into the quiet backroads and singletrack of Jackson Demonstration State Forest. The route mixes fast, smooth dirt roads with rougher forest sections, steady climbs, and a few technical bits that keep things interesting. It’s a route that rewards pacing and bike handling as much as fitness.

You’ll roll through dense redwoods, coastal fog, and stretches of open ridge with classic Mendocino vibes all around. While it’s doable on a gravel bike, a hardtail or XC bike will be the better call for most riders. It’s a solid day out, challenging, beautiful, and full of that remote, backcountry feel that makes the Hoppers what they are.
