The trail is rated with a smiling green circle in an approachable blue square, just a step up from the easiest terrain for beginner mountain bikers. The dirt is rusty from a winter’s worth of decomposing pine needles and redwood bark. Spongy from last night’s rain, it sucks the momentum from the his tires as he approaches each lippy mound. Still, when he leaves the ground you can see that the rider has style: He turns the handlebar, whips the back end of the bike in the air.
