About
Ross Valley Mountain Bike Camp
Marin County Mountain Biking For Kids Aged 8 to 14 Years Old
Ross Valley Mountain Bike Camp was founded by Otis Guy, who is recognized internationally as one of the founders of mountain biking.
While the name has changed our philosophy remains the same.
We are dedicated to equipping the next generation with core mountain bike skills and fostering an appreciation for the outdoors and trails of Marin.
Our experienced team is committed to providing an inclusive, safe and fun environment for kids to learn, grow, and explore the world of Marin County mountain biking.
The team of counselors is made up of experienced mountain bikers, and we're fortunate to include both teaching and healthcare professionals within our crew.
Located in Fairfax, Marin County, California. The camp caters for kids aged 8 to 14
CAMP DIRECTOR
Hi! I'm Paul Whitfield
I'm a life long cyclist and former UK national champion, having raced and trained all over the world from the age of 12. Cycling has been a huge part of my life and I have a deep appreciation for the experiences, friendships and opportunities it's given me! I'm so happy I can share this wonderful sport with our campers!
I have multiple years of coaching experience in the UK having worked with the English Schools Cycling Association.
In 2025 I took over Otis Guy's Mountain Bike Camp, it was a truly rewarding and fun experience running the camp and sharing my love of mountain biking and the trails of Marin!
We're fortunate to have Otis on hand, to work with counselors and oversee the camp.
Its my goal that our team provides an inclusive, safe and fun environment for every attendee to thrive.

Carson is arguably one of the most talented bike riders, not to mention one of the most decent human beings you’ll ever meet (he is beyond modest)! This former national champion, has dedicated his life to working with kids, as a cycling coach and in his 9-5 as a school teacher.
Carson has extensive experience when it comes to leading mountain bike camps, as a former head coach at San Domenico HS and previous mountain bike camp leader. Suffice to say we’re beyond excited to have Carson on board as our lead counselor for 2026!

Zach Rice
My name is Zachary Rice, but I just go by Zack. I’m a sophomore at Terra Linda HS and have been racing for the past 4 years. Mountain biking has always been a part of my life, and I grew up going to Otis Guy MTB camp. I was very glad when I heard that Paul brought back the camp after Otis retired, and I became a CIT at Ross Valley that summer. During that time, I established a deep personal connection with the camp, and I’m glad to be back once again as a full counselor working with the new and older riders.

Hi! My name is Rhys, and I am a graduating senior at Archie Williams High School. I have been passionate about mountain biking ever since I moved to Fairfax in middle school. Throughout my high school career, I've raced mountain bikes and worked at Sunshine Bicycle Center, which has given me opportunity to build community and meet inspiring people like Carson! (our lead counselor!)
Over the past two summers, I’ve had the privilege of working as a bike-camp counselor, where I have supported campers in growing their skills while having fun too. I’m excited to return this year and keep sharing the magic of Mountain biking with others!

2026 Support Staff
Bebe
Hi! My name is Bebe and I'm 10 years old. My new owners, Tina & Paul came and adopted me from Muttvillle at the beginning of 2025 and I couldn't be happier with my new family. They take me to Ross Valley Mountain Bike Camp so I get to meet all the new campers each week! If you see me at camp, please come and say hello as I love making new friends!
While I'm not very good at mountain biking, I really enjoy riding along the trails of Marin in my backpack, stopping for snacks and of course an ice cream from Scoops at the end of the day is a highlight (sometimes dad shares with me)!
