Welcome to the “Endurance Box”, Lubbock’s elite training program designed for single and multi-sport endurance athletes. We provide a uniquely effective training program and supporting resources to athletes who want to achieve peak performance in their endurance sport.
Who we train
We train any athlete whose sport involves endurance including trialthletes, swimmers, cyclists, runners, adventure racers, and ultra-endurance athletes.
How Endurance Box is different…
Endurance Box is an extrememly effective training program based on CrossFit Endurance training techniques that increases the participants general cardiovasular and respiratory endurance, stamina, and increases efficiency in the athlete’s posture/form in monostructural exercises (running, rowing, swimming, cycling, etc.). Typical endurance athletes train long and slowly, constantly building a “base” for that next race. This produces constant pounding on joints and wear and tear to muscles resulting in trauma that could potentially disable one’s long-term racing goals. In contrast, we train athletes based on the science of the four metabolic pathways. Our volume of training is lower and more intense, keeping over-training, burnout, workout recovery time, and injuries to a minimum. We combine the CrossFit model of high intensity (HI) core-to-extremity movements and training and skill development that supports meeting the specific demands of endurance sports and increasing the athletes general endurance, efficiency, and stamina.
The Community
The Endurance Box is not just a training program, but a thriving community of athletes who work together to improve both their times and lives. Along with our classes and our weekly Saturday morning time trial or tempo runs, we will be choosing local and regional races to attend and compete in as TEAM ENDURANCE BOX. The community makes the difference!

The Endurance Box Coach…
Certified CrossFit Endurance Coach, Geoff Lynn, will oversee the Endurance Box program and its athletes. Before joining a CrossFit training community, Geoff trained in the typical LSD (long, slow distance) training method. He eventually became burned out from the hours he spent on the road. Once he switched to CrossFit, he PR’d (personal record) on his half marathon by 10 minutes with 70% less training than with his previous LSD training method. Geoff has raced in several sprint distance to half Ironman distance triathlons as well as run several 5K to marathon distance runs. Geoff’s passion for helping others achieve their goals though training and support, his effective communication, and love for endurance sports has brought his unique skill set to the Capstone CrossFit staff.
