John Austin - Owner and Head Coach

I provide customized coaching programs for triathletes and runners competing in races of all distances. Each training plan is developed and adjusted weekly to fit the goals and constraints of the athlete. 

I work with athletes of all ages racing all distances. I specialize in working with masters athletes competing at long distances – marathons, half and full iron distance. 

Fully  retired from corporate life, I can now devote my full energy to sharing what I have learned over more than 25 years of running and triathlon.
