Purplepatch Pillars of Performance


This is the sport specific demand placed on the body to trigger adaptations in the areas of swimming, biking, and running.  The purplepatch focus of this training is to achieve the necessary volume while combining it with healthy lifestyle practices to avoid accumulated fatigue and improve performance.

Functional Strength

Functional strength is resistance training to target mobility, stability and strength to support and improve the movements necessary for a specific sport.  Proper and progressed functional training can improve your biomechanics and efficiency of different muscle groups which all lead to more athletic movements, improved performance, and injury prevention.

Nutrition & Fueling

Nutrition and fueling are what purplepatch fitness uses to highlight the specific purposes of calories intake. They are distinct, yet synergistic aspects of an optimal nutritional approach to support training.  Fueling describes the calories needed to successfully complete a training session or event.Nutrition will encompass the remainder of an athletes diet, outside the fueling window.


Recovery is the body’s physiological process to compensate for the demands of a progressive training load.  Physiological adaptation (e.g. metabolic rest & rebuilding) of the body takes time and must be structured in order to elicit the changes that will optimize athletic performance.

Matt Dixon brings a unique blend of professional coaching experience, elite athletics and education to lead the Purple Patch team. His Master’s degree in clinical and exercise physiology combined with his experience as an elite swimmer and professional triathlete form the backbone of his coaching philosophy, the Purple Patch Pillars of Performance, a much broader and adaptive view of the path to peak performance than conventional endurance sports coaching. He is a highly sought after resource in the fitness and endurance community, writing and contributing to multiple publications and organizations such as Triathlete Magazine, USA Triathlon, Outside Magazine and Powertap. He has also been featured in the Wall Street Journal, New York Times, Men’s Journal, Outside, Men’s Fitness, and Men’s Health.

With Matt Dixon’s Purple Patch Pillars of Performance, athletes of varying goals and capacities are able to train throughout the week using the same philosophy and methodology. The Purple Patch mission is to create an effective program for all to follow, without forcing athletes into a standardized program that simply doesn’t fit into their life.

Tom started helping out with purplepatch back in the days when Matt ran the site from his laptop. His involvement grew as the company grew, eventually joining fulltime in the summer of 2014.  Tom is a former Division 1 colligate swimmer that continues to train and coach swimming today. He has an MBA with a focus in technology. His experience spans 20 years in Technology Operations Management, Development, and Product and Program Management.
