Intensity Endurance was founded in 2020 by former professional triathlete and NCAA Division 1 swimmer, Gunnar Eichler. He wanted to create a coaching and team environment that is tight knit and supportive.

Gunnar specializes in two unique concepts in endurance training:

The first is training endurance athletes with a base of VO2 + work. High intensity is the key to getting faster, fitness should be added on top of the speed. (Hence, Intensity Endurance).

The second is proper swim coaching, something that you cannot get from even the top youth and college coaches. He will teach you how to become a good swimmer, not just be a fit swimmer. The belief that learning to swim as an adult is not any disadvantage.

The focus is on elite level performance, getting athletes to reach their goals, like Boston Marathon Qual, Kona Qual, Pro License, PRs, etc. But Gunnar also ensures to keep a healthy training-life balance for all of his athletes.
