David’s approach to endurance training is driven by the latest empirical research. From the broad annual training plan down to the individual interval of a single workout, the decisions and recommendations are rooted in his evidence-based philosophy.


Your custom training plan is developed using your specific goals, strengths and weaknesses, and constantly modified based on frequent review of workout results.


David believes that the athlete-coach relationship is about achieving outcomes that could not be accomplished individually. His coaching style and execution are best matched with athletes seeking real results.
