Pure Endurance

Jonathan Booth

Owner/Head Coach, 

B.Sc., USAT Certified, CSCS, Training Peaks Level 2 Coach, Certified Bike fitter

Jon grew up in beautiful Central Oregon competing against his older brother in many endurance sports. The thrill of competition pushed Jon to chase his brother from behind or hold on strong to his lead. Eventually, this led to competing at the ITU World Cup in Maui as a junior.  That experience at a larger venue cemented in him a love for the sport that would largely lay dormant for years.  That is until the need for a career change from the high stress and sleepless nights of the fire service led him to start his own business.  Having coached athletes from first-timers to Ironman finishers, and Ironman 70.3 World Championship qualifiers. Jon has built Pure Endurance from a single endurance athlete to a team of supportive coaches and athletes..  Coach Jon has now regained the racing bug; partly just to keep up with his ever increasing speedy athletes. Making a return to the sport, Jon is enjoying chasing some goals in the 70.3 triathlon distance, local trail races and attempting to regain some of his run speed from his youth.

Kristen Lipscomb, PhD.

IRONMAN University Certified Coach; RRCA Certified Running Coach

Kristen grew up in Rochester, NY playing sports (soccer and ultimate frisbee) through high school and college. Well into her athletic career, she suffered two ACL tears and a shoulder labrum tear, all requiring surgery. Although she was determined to not let these prior injuries stop her, she was skeptical about how her body would hold up to the demands of endurance sports events. Ultimately, sustaining and treating these injuries led Kristen to pursue a PhD in biomedical engineering to better understand human movement and biomechanics.

While Kristen was in graduate school, she ran to augment weightlifting at the gym. She constantly worried about how her knees would fare with pounding the pavement, but was amazed with how well they handled the stress with a gradual progression into distance running. In 2010, Kristen completed her first running race, a 5k, and was immediately hooked by the atmosphere. She continued with half and full marathons (including qualifying for the Boston Marathon), then a triathlon and completed her first Ironman in 2017.

As a full-time working professional, Kristen understands the need to help athletes balance the demands of work, family and life with their athletic training and goals. She loves helping people challenge themselves by setting goals and finding their edges, but doing so within the context of other life commitments. She wants her athletes to get true joy out of the process and realize they are capable of so much when they are consistent and committed to a goal. 

Kristen works as a biomedical engineer, focusing in injury biomechanics for the legal consulting industry. She enjoys spending time outside with her husband, Ryan, who is also an endurance and multisport athlete, her two children, and her dog.
