David Sheek

David is an Expert Coach with Carmichael Training Systems based in Southern California. When Sam asked him and Amanda Nauman to come to Bakersfield in 2014 for a “really long cyclocross race,” they jumped at the opportunity to humor Sam and have been hooked on this stupid ride ever since. Most notably, Dave has been the coaching force behind Amanda's five Cobbler wins from 2014-2018 and acted as the lead coach for two CTS Training Camps in 2017 and 2018 in Bakersfield. Safe to say, Dave knows the ins and outs of this event, its evolution through the years, and insight into Sam's psychotic ideas. Aside from that, his knowledge and expertise in all areas of dirt and endurance events span a decade and his best skill is crafting a training plan that fits you and your lifestyle.

I strive to deliver athletes more than just a training plan, no matter what their abilities or goals. I pride myself on helping plan out an athlete’s season to meet their goal events. There is science in training but also an art in creating a balance for athletes to help them stay on target.
