OPTION #1: 80 MILES   /   8,176 FT
OPTION #2: 62 MILES / 6,753 FT

Riders choose between two routes: the full King Ridge Dirt Supreme course or the route minus the climb to Occi and the Willow Creek descent. If you are looking for a supreme cross/dirt/gravel challenge this is it.

Ideal bike set up? Either a road bike with 28-30c tires and low gears or gravel bike with 30-35 slick or slight tread. Like always, Hopper routes make it tricky to pick the perfect combo.

Grasshoppers have always been about adventure, exploration and pushing your limits. All Hopper routes are open and riders must obey all traffic laws and rules.

Cash prizes for top three male/female riders.
