THE MEGA HOPPER

October 17th, 2025

Welcome to the Mega Hopper, a fully self-supported, the absurdly ambitious 416-mile linkup of 9 major and legendary Hopper routes. This is the ultimate test for your gravel endurance.

This isn’t a race or a traditional event, really, it’s an idea, a challenge, and a chance to dig deep, ride long, and test yourself across the a combination of the same legendary mixed-terrain Grasshopper courses we have ridden over the years.

Weather your coming for the FKT (Fastest Known Time) or the FKT (Funnest Known Time) this is amazing opportunity to cover some ground in a very special area.

Route

416 miles and 46,000 of elevations through Sonoma, Marin, Lake and Nap Counties. This is essentially the greatest hits tour of Grasshopper routes and all the legendary roads the area has to offer. This route includes the classic Hoppers Old Caz, Chileno Valley, King Ridge, Fort Ross, Super Sweetwater, Super Skaggs, Ida Clayton/Spring Mtn., Bear Valley and The Geysers. Though primarily paved roads don’t let this fool you. For many of the roads in Sonoma County you will be stoked be on a wide volume tired gravel bike. The dirt sections include Mt. Vision, Inverness Ridge, 5 Brooks to Olema Valley, Bolinas Ridge, Willow Creek, Old Caz, Skaggs (Lake Sonoma Single Track is not in the route this year) and Western Mine Rd.

What is an Ultra?

An Ultra Bikepacking event is a long-distance, self-supported cycling challenge. Riders navigate rugged terrain over hundreds of miles, carrying all their gear and managing their own food, water, and repairs. There are no aid stations or support crews, just you and the ride.

You can take on the challenge however you want: join a crew of friends or embark on a solo "vision quest." The focus isn't on speed, but endurance and self-sufficiency. It’s about testing your limits, exploring remote landscapes, and experiencing the journey, not just the finish line.
