Joy and Brian McCulloch are the husband and wife team behind the southern California-based Big Wheel Coaching. Joy was a high school P.E. teacher and professional mountain biker. Her vision behind Big Wheel Coaching was to bring P.E. to adults by providing structure, feedback and accountability to athletes. Brian joined the business in 2016 and has over 15 years of professional road, mountain bike and gravel racing experience, and he currently races for the Bianchi Gravel Team. Big Wheel Coaching has developed a Race Day Ready program to help their athletes hit collaborated goals. Joy and Brian develop a plan — many times a physical plan — to achieve the desired objective while also preparing for various aspects they will encounter during a race that might be unique to the course or new to the racer. In addition to the planning, they attend the races to guide mini-clinics on the days before or day of the race to help guide clients and, at times, other racers to be aware of situations they may encounter on the course. Or to get off the line with an opportunity for success. Listen in as they talk about what they've found essential to help racers successful in a race day "stadium" that many have limited experience with or limited occasions to practice.

If you identify with the mountain bike crew and or with the data nerd clan, this episode is for you. Matt Miller, mountain bike scientist and founder of BrakeAce sat down with Dirk to explore all ways of improving speed and fitness.

They also discuss the absolute necessity of preserving high-effort "matches" by way of strategic braking and finally wrap up with debating how much time mountain bikers need to spend on the road.
