Michael joined the CAMTB team shortly after the organization’s official launch in January 2020, but he has been developing and leading cause-based coalitions and member organizations since 2008. His approach is built on a foundation of progress through partnership, shared resource development, and collective action.

Michael moved to California in 2008 following an eight-year run in the San Juan Mountains of Colorado. He is an avid mountain biker, skier, hiker, and backpacker.

Steve began riding Australian backcountry in the 1970s before moving to California and joining the mountain bike scene in the early 80s. A lifelong advocate, he helped organize the nation’s first Forest Service-sanctioned MTB race and has been a core member of the Over the Bars MTB Club since 1993.

Disturbed by deteriorating trail conditions, Steve began leading volunteer crews in the early 2000s. He joined the CORBA board in 2009 and has served as President since 2014, leading major post-fire trail reconstructions and championing the development of new bike parks.

Today, Steve holds leadership roles with the California Trail Users Coalition and the San Gabriel Mountains National Monument Collaborative. He is also the co-author of Where to Bike, Los Angeles Mountain Biking and a founding member of CAMTB.

Susie Murphy started riding mountain bikes in the early 1990’s in order to follow her husband who had taken up riding with their young daughter in a backpack. She wanted to keep an eye on them, but they soon discovered a family pastime that took them on many adventures. Some of their best times were camping at the Sea Otter Classic, traveling to races down in Baja, going to 24-hour races, and many other adventures with awesome friends.

Susie has volunteered in the cycling community for many years with over 25 years with various groups. Susie was the Executive Director of the San Diego Mountain Biking Association for 10 years. She currently serves on the San Diego County Parks Advisory Committee, the Otay Valley River Park Citizens Advisory Committee and is a board member of Ride Krew, a non-profit dedicated to getting more kids on bikes.

She is inspired by the dedicated volunteers of SDMBA and other partner organizations and loves connecting with fellow advocates locally, statewide, and nationally.

John lives in Orange County and has been mountain biking for over 15 years. He and his wife, Margie, are passionate about mountain biking and hiking and enjoy exploring new trails around the state and country. He is excited to see the increase in people enjoying the outdoors as well as the diversity of trail use. He is honored to be a board member advocating for trails in our great State.
John is inspired by the dedicated volunteers of his home trail advocacy organization Orange County Mountain Bike Association and is looking forward to expanding his network and engagement with fellow advocates locally and statewide.

We are all in this together, so let’s go out and enjoy the great outdoors and be kind to one another while sharing the trails!

Raised in northern Appalachia and refined in the Colorado Rockies, Leah moved to the North State in 2024. While new to California, Leah has worked professionally to create, enhance, and maintain trail infrastructure across the country in different capacities for the last 7 years. During and immediately after college, Leah went to work for a landscape architecture firm in the Roaring Fork Valley specializing in habitat restoration and ecological design. The technical skills she learned in that role translated well when the opportunity arose to turn her passion for mountain biking into a career. 

From 2020 to 2024 Leah worked as a trail planner, designer, and project manager for IMBA’s Trail Solutions team. Her work with IMBA brought her to Redding, and Redding’s limitless recreational opportunities compelled her to stay. Now managing projects related to trails, parks, and open space for the City of Redding, she relishes the opportunity to have more local impact in a community that shares an indescribable kinship to the hills she grew up in on the other side of the country.

You are sure to find Leah in one of two places: At her desk making maps for the next adventure or somewhere on that map.

Jake Bayless is a life-long resident of Sonoma County. In addition to being the co-founding President of CAMTB, he was co-founder of REMBA, the Redwood Empire Mountain Bike Alliance, and participated in the organizational merger with the Sonoma County Trails Council in 2021, becoming a co-founder of the newly merged 501c3 organization; The Redwood Trails Alliance, RTA, which now serves three counties of Sonoma, Lake and Napa. As CAMTB has grown in size and influence, Jake has focused his volunteer efforts entirely on CAMTB.

Jake fell in love with his wife on a moonlight mountain bike ride on Mount Saint Helena; they have two active sons participating in NorCal NICA league races. Their whole family loves to ride bikes in places like Annadel, Salt Point State Park, Montana de Oro, and Jackson Demo Forest. Jake’s regular job is programmer/analyst for the City of Santa Rosa, and he’s always looking for a better map.

Why CAMTB? Because we’ve all seen that trail development and expansion isn’t happening in proportion to the growth of mountain biking and outdoor activities generally in California. Jake, and the other co-founders of CAMTB found that locally it was nearly impossible to get all the various “bike groups” on the same page to actively influence park and open space decisions. Jake believes that California has a lot of catching up to do; it has now been 40 years since the invention of the term “Mountain Bike”—in California. It’s time to get together to ensure that everyone in California has a chance to enjoy all the trails and healthy lifestyles in our beautiful state on a bike. CAMTB is how we’ll do it. You’re always welcome to reach out and say hello.

Matthew serves on the board of the SF Urban Riders.

Matthew Blain grew up riding bikes in Philadelphia’s Wissahickon Valley and has been interested in bicycle and trail issues in the decades and cities since then.

In 2008 he moved to San Francisco and became more involved both in Mountain Biking and bike advocacy, becoming chair of the local MTB group SF Urban Riders in 2015. In addition, he is part of the SF Crosstown Trail Coalition and the Bay Area Ridge Trail SF Trail Advisory Group.

Matthew joined the CAMTB board in 2019 and became Treasurer in 2020.

Sonja Johnson joins CAMTB with over 20 years’ of experience in the bicycle industry, starting her career at a bike shop in 2004 and soon transitioning to sales representative for SRAM in 2008. Currently, she leads SRAM’s South & Southwest In Market Field Guide Team and works at SRAM’s San Luis Obispo location.

Raised in the Greater Boston area, she pursued marathon running after a college soccer career. Upon relocating to San Diego, she naturally transitioned to triathlon. Following an accident that made running difficult she made the switch to endurance road riding and was an early adopter of gravel racing and mixed-surface events.  

While not an avid mountain biker (yet), her work at SRAM and RockShox embeds her in the flat bar world daily.  

With a keen interest in the legislative process and being politically engaged, Sonja aims to bring her industry knowledge and perspective to CAMTB.

Rob’s advocacy priorities include bike-optimized trails and bike parks, climate action, trail access for urban and disadvantaged communities, and increased funding for our public lands, especially the USDA-Forest Service.
