The Breakthru Philosophy


At Breakthru, we see each athlete as a unique person with strengths, weaknesses, race goals and having mental, physical and time constraints. Through conversation about goals, past training (what they enjoyed, liked, dreaded), injuries or physical limiters, we form a basis for a starting point in terms of volume and intensity.  

Beginning a training plan from theory gives us the framework to get our athletes to the starting line of their race.

As is said in business, "if you cannot measure it, you cannot manage it", applies in coaching, so with that concept we continually refine the training plan to account for what we see in the workouts (completion, hitting intensity, hr, power, pacing), the mental state (level of fatigue, discussion about their perception of how training is going). Based on testing, training adaptation, physical shape (soreness, tightness, oncoming injury) and mental state, the plan is continually adjusted to exploit/build their strengths, improve/limit their weaknesses and maximize training capacity. Some people become "ahead of plan" and get more challenging or longer duration workouts and others go at a little slower pace and may require hard conversations about meeting or modifying their goals.

All of this is factored into each athletes unique plan.
