If you are interested in taking your athletic performance to the next level - whether that next level is beginning a training program for the first time, improving your personal best time, winning your age group, or turning professional - you came to the right place.

Joe Company, PhD founded ECo in 2010, but prior to this he coached at the high school and collegiate level, worked with Olympic training programs, and worked with a number of high-performance athletes, scientists, researchers, and coaches.  Joe began consulting endurance athletes in 2002, but as he evolved in his education and experience, he wanted to make his expertise available to more people.  ECo is the product of Joe's experience.

Endurance Company coaches and partners are carefully selected to provide quality coaching, teaching, information, and advice. All ECo coaches provide a valuable combination of education, practical experience, and knowledge in Joe's training philosophies.  Endurance Company coaches apply these key principles to provide unparalleled, customized training programs for all abilities of athletes. 

Our mission is make your training and racing experience as rewarding as possible. The goal is to help you become a healthy, successful, complete athlete by providing a training plan that helps you reach your goals while maintaining balance in your life.

In addition to custom training plans, we offer laboratory bike and run VO2max and lactate testing as well as 'field testing' for bike power. These tests allow unparalleled optimization of your training plan.

It is time to take the guesswork out of your training!
