HUFFMASTER

February 28th, 2027 Register

Join us for the classic Huffmaster starting in Maxwell, California. West of Hwy 5 and east of the Mendocino National Forest lies miles of rolling gravel roads and lightly traveled tarmac that few have seen on two wheels. Two routes to choose from—89 or 59 miles—and less climbing than a typical Hopper make these mixed-terrain routes a real treat. Special revised course for our 30th Annual Grasshopper Series!

Route

Huffmaster: The course starts at Maxwell Fire Department. This year we head west and take a left on Sutton Rd. for the first gravel section. The course zig-zags for 15 miles along the flats until hitting the first climb. Leesville Rd. is a 1,500 ft climb over 10 miles. Over the top we head past Huffmaster and continue on to Ladoga and take a left at mile 37 and continue for 13 miles though Stonyford to Rail Canyon Rd. Rail Canyon is an 8 mile ripping gravel dirt/gravel road that climbs 800ft. The route then heads down hill and continues on to Huffmaster Rd. There is a short 400ft gravel climb to the top of the summit before the course continues on gravel through for 10 miles to the “town” of Sites. In Sites, we get back on pavement for 5 miles before turning right off the main road to finish it out on on gravel.

Huffmaster Short Course: The course starts at Maxwell Fire Department. This year we head west and take a left on Sutton Rd. for the first gravel section. The course zig-zags for 15 miles along the flats until hitting the first climb. Leesville Rd. is a 1,500 ft climb over 10 miles. At mile 27 you take a right on Huffmaster Rd. There is a short 400ft gravel climb to the top of the summit before the course continues on gravel through for 10 miles to the “town” of Sites. In Sites, we get back on pavement for 5 miles before turning right off the main road to finish it out on on gravel.

Adventure Therapy Foundation

A portion of the proceeds from your Huffmaster registration will go to Adventure Therapy Foundation. A.T.F. was created to “minimize the emotional side effects of cancer”. Lauren Huffmaster is a cancer survivor, mother, speaker and writer. Her husband’s family grew up on the Huffmaster ranch, at the base of the Huffmaster grade that Hoppers pass through.

All registered riders can donate directly to ATF and create a fundraising page when they sign up. We all have friends and family living with and impacted by cancer. Let ‘s spend the day riding our bikes with friends in their honor and lend a hand to those whose lives are affected by cancer. Our goal is to raise $10,000 that will send 4 families living with cancer to adventure camps this Summer.

Also, we’ll be holding a donation drawing at the afterparty for Huffmaster. Grasshopper. We have an AHHA Bike Rack, Burley Coho XC Trailer, Trailhouse Demo Day for 2, a Grasshopper 2026 Series Pass and other amazing prizes to raffle off. Everyone who makes a donation and raises funds will be eligible to win the drawing. The more you donate, the better your chances.

“Adventure Therapy Foundation began in the summer of 2018, a year after our (ATF) founder Lauren met a stranger in an airport who engaged her in conversation. They listened to her journey through cancer and asked her, ‘What do you want to do with your story?’ This question sent Lauren on a search through Yosemite for answers, and she found the beginning of a dream. A dream to use adventure to help those impacted by cancer escape the emotional “rut” that occurs after treatment. From there, Adventure Therapy Foundation was founded, and here we are years later, seeing hundreds of individuals dealing with a cancer diagnosis that have been guided through the mine-field of emotions, into a place of healing and restoration.”

More Info

  • Maxwell, California is a small agricultural town in Colusa County, California, located along Interstate 5, about 75 miles north of Sacramento. Known for its rich farmland and quiet rural charm, Maxwell sits on the western edge of the Sacramento Valley, bordered by rolling hills leading into the Mendocino National Forest. The area is a gateway to remote backroads, open landscapes, and classic gravel riding—making it the perfect setting for the Huffmaster race.

  • In late February, Maxwell serves up cool, crisp mornings and sunshine-warmed afternoons—perfect for a day on the bike. Temps start in the 40s but climb to the mid-60s, so layering is key. Rain? Maybe. Wind? Almost definitely. Expect some grit-in-your-teeth headwinds early on, but hey, that just makes the tailwinds feel even sweeter. The gravel? Fast, hard-packed, and ready to rip—just like you should be.

    *In case of extreme weather there is a Plan B route in place!
