Eric has been with the camp for seven years. He’s been a Ross Valley District teacher for the last 20 years and is now a fifth-grade teacher. He has a great sense of humor, incredible cycling skills, and knowledge. Eric began riding mountain bikes in Annadel State Park in the late 80's while in high school and hasn't stopped. After working at bike shops throughout college at UC Davis and road racing, he received a degree. Eric began working as a mechanic for Mavic, Shimano, SRAM and Drake MTB. He has worked for many race teams across North America at the Tour of California, many U.S. National Championships, World Championships, and PanAm games. Safe to say Eric will be able to help get all the campers' bikes running well. Eric was the longest-tenured coach on the Drake High School MTB team.
Eric is excited to spend a few weeks helping the campers learn new skills, help them make new friends and find the same joy in riding their bikes that he has found over the years.

He has great communication skills, riding ability, and is an overall funny and nice person.


Our camp is about having fun and learning cycling skills. Our mission is for our campers to have fun and come away with the skills and knowledge to be able to take you on some great bike rides out of Fairfax. 
No other camp exists that has this depth of background of cycling knowledge and has the preparation to handle any emergency.


Otis was the Co Head Coach of Sir Francis Drake High School Mountain Bike team for 5 years and has been running a mountain bike camp instructing kids ages 8-13+ for the last ten years. We do have riders under 8 attend, please make sure they have the right bike and can ride uphill a little bit. Our campers will have the best safety protocols in place from not only emergency medical knowledge, but also from untold hours of leading rides for riders of all ages.  

We have a large diversity of riders from ages 8-14 years old that come from all different kinds of riding backgrounds, from beginners to advanced. We split into groups to give each rider the best camp and riding experience.

What kind of bike do they need? What about clothing? What else should I know about attending camp?

They usually need a 24" wheel or bigger mountain bikes with 3 front chainrings (many bikes now have single chainrings but with very large cogs in the back, that bike would work!!) and low gears. What can make it very difficult for the riders is a bike with a single chainring and smaller cogs in the back. It is not about how fast they go up a hill, just that their gears are low enough to still pedal. If you have any questions regarding this, please give me a call. If they can’t fit 24” wheels, make sure their 20” wheel bike has low gears.  Also, the 24" or bigger wheels roll over bumps much better, which makes it much easier for them to improve their skills. We need all bikes to have at least one water bottle cage to keep the campers hydrated. Some riders use a camelback-type backpack to carry water. Make sure they know how to use it and are filled up when they arrive. In terms of clothing, if it's going to be a cool day have them bring a sweatshirt. We want the riders to wear some type of gloves as it helps protect their hands if they fall (it does happen occasionally). Please sunscreen up your camper before they arrive, as this is an all outdoors camp. We bring sunscreen with us if more is needed. On the last day of the camp session, we go out and ride to the inkwells near Lagunitas so if they can carry a swimsuit with them. Many campers wear their swimsuit and air dry (no towels needed), but there is a place for them to change. If there is any reason you don't want your camper to swim please let me know. 

I'm worried about if my child will last all day in a mountain bike camp?

A typical day starts out with bike checks. Each day we demonstrate and work on a specific mechanical skills as well as practical riding skills. Some examples of these skills include learning how the gears work and how best to shift, the parts of a bike, how to use the brakes, how to remove each wheel and how to fix a flat. We then go for a ride and have lunch. To conserve energy, we will play games to take a rest from riding. Sometimes we do a shorter ride or skills session. We finish up at the Fairfax Scoop and if campers would like get an ice cream they can (please supply your camper with some money to purchase an ice cream if they want one).   

Is it okay if my camper rides to and from the camp?

We do have some campers who have no problem riding to and from their home to camp. If your camper is skilled enough and you feel confident that they can do that, we are fine with your decision. 

How do you handle having riders of differing abilities and ages?

We split into groups depending on the skill and ability of the riders. That is why I have you let me know what level you think your camper is at. We take different routes to get to the same place to give each camper an experience that best fits into their strengths. That being said, sometimes riders move up a group if they are feeling stronger one day or maybe move down if they are tired from the day before. We have routes and locations that we want to get to each day, but we read the room and see how everyone is doing and adjust accordingly. It could be a hotter day and our route may be adjusted to have the riders ride in themselves around cycling. Our philosophy is to always keep looking at ways to make sure that all the rider’s needs are met. This means we may have a goal or route in mind though depending on how the campers are feeling we always adjust to make sure we keep them feeling confident while still getting them to push themselves.

What about food/lunch?

We provide snacks during the day. A small handlebar bag is supplied for use during the entire week. It is large enough to fit lunch, size is 9"s long and 4.5"s in diameter. It won't fit the large metal or plastic lunch containers. Some days we return to our starting place and have lunch locally. Other times we have lunch while we are out on the trails.

Does my camper need to be an experienced rider?

No, they simply need to be able to ride a bicycle safely. During the week we work on how to shift the gears properly and how to use brakes efficiently and safely. We teach them how to ride safely on the street and on trails by learning what to look for while riding and maneuver in the safest manner possible. The camp is about giving each rider the confidence to feel better about how they are riding. it is not about how fast anyone one of them goes, this camp is about having fun and learning how to ride.

If my child has a drug or food allergy are you equipped to deal with that?

Yes. I am a trained paramedic (very few camps -- if any-- have the medical and trauma experience that I do) and can assist with an Epi-pen administration. Please indicate on the registration form what allergies your child has so we can best accommodate them. If they are prescribed an Epi-pen please bring it each day of camp. It will travel with them in their handle bar bag. 

What about afternoon rides?

When you do the afternoon rides, the dates will be on the home page of my site and will be in both the 2021 registration form and the short form for registered 2021 riders who already completed the long form

Where do we meet and pick up?

We meet at Central Field at 8:30 am in Fairfax. It is the baseball field right near downtown Fairfax off Broadway behind the Bank of America on School Street Plaza. We are usually back at the ball field by 1:45 -2 pm if you need to pick them up early. Otherwise camp ends at 3:00 pm (also at the field). For afternoon rides we meet at 1966 SFD Blvd FFX the Marin Museum of Bicycling

"This is a bit overdue, but I wanted to thank you for taking Sam at the last minute when your camp said it was full. He loves mountain biking and has the utmost respect for you, your boys and Eric. What great role models you all are!!! Thanks for inspiring him and challenging him. We sure are lucky that he is learning from the best!"

"I wanted to personally give you kudos for Luke’s newfound love of the bicycle. He rides it every day to school (rain or shine) and has gone mountain riding a handful of times. Took him riding on Wednesday and saw something I have never seen:  a true love for the bike! He ripped up the hills and down them. I can’t thank you enough Otis. Magical!"
