  • Under the Hood: Mapping Muscle Fiber Utilization to Training Zones
    Feb 21 2026
    This audio overview, titled "Under the Hood: Mapping Muscle Fiber Utilization to Training Zones" is a deep-dive overview where we explore the physiological anchors that define the QT2.0 training system. Rather than focusing on arbitrary percentages, we examine how Critical Power (CP) and Critical Speed (CS) serve as the definitive asymptote and boundary between physiological stability and instability. We break down the transition of energy systems from the steady-state recruitment of Type I (slow-twitch) muscle fibers in Z1 to the Type IIA Oxidative and Type IIA Glycolytic fiber recruitment that characterizes the move through Tempo (Z2) and Threshold (Z3). Finally, we look at what happens when you "raise the roof," moving into maximal aerobic intensities that recruit Type IIX fibers and draw from your finite anaerobic tank, known as W′ or D′. Discover how understanding these internal shifts allows you to move beyond "no-man's-land" training and toward a truly deliberate and intentional approach to performance. *This audio overview is AI-generated off of QT2 Systems' knowledge-base of source materials.

  • QT2.0 Deep Dive AI Podcast - Raise Your Ceiling or Raise Your Roof
    Feb 14 2026

    This audio overview, titled "Raise Your Ceiling or Raise the Roof," provides a deep dive into the Athletic Architecture model used by QT2 Systems to determine an athlete's ideal training focus. The episode explores the critical relationship between an athlete's sustainable threshold - their "ceiling" - and their absolute high-end capacity - their "roof".

    The discussion centers on how the ratio between Critical Power/Speed and power/speed at VO2 Max defines an athlete's physiological state and dictates which of two primary training paths will offer the highest return on training investment:

    • Raising the Ceiling: The hosts explain that for athletes in an Anaerobic physiological state (ratio < 85%), the "attic space" is too large. In these cases, the priority is a Build/TH block designed to lift the ceiling closer to the roof, making more of the athlete's existing capacity usable for longer durations.
    • Raising the Roof: Conversely, for athletes in an Aerobic physiological state (ratio > 88%), the "attic" has become a "crawl space," meaning the ceiling is pushed right against the roof. The hosts discuss how a VO2 Max block can be used as a targeted intervention to lift the absolute upper limit, thereby creating the necessary physical space for the threshold to grow in the future.

    Throughout the overview, the hosts emphasize the importance of intentional training. By using testing data to identify whether an athlete needs to focus on their sustainable potential (the ceiling) or their absolute capacity (the roof), coaches can avoid a "scattershot approach" and ensure that resources are not wasted training energy systems that are already well-developed. The episode concludes by reviewing how these physiological decisions fit into a broader framework that also considers practical factors like injury history and race proximity.

  • QT2 Systems - Why Mindset Matters in Endurance Sports - Episode 6 - Maintaining a Larger View

    Why Mindset Matters in Endurance Sports and How a Coach Can Help Navigate the Minefield - Episode 6 - Maintaining a Larger View/Managing a Disappointing Result

    In this podcast series, QT2 Owner and Head Coach Tim Snow shares his views, informed by more than twenty years of racing and coaching endurance sports, on how an athlete's mindset can have a profound impact on performance.

    What happens when you nail your training, but fall short on race day? It could be for so many reasons. In this final episode of the series, Coach Tim talks about the race debrief, and why it's such an important conversation to have. It's always important to try to understand what happened and why - often the answer is not the training.

    Why Mindset Matters in Endurance Sports and How a Coach Can Help Navigate the Minefield - Episode 5 - Coping Visualization

    In this podcast series, QT2 Owner and Head Coach Tim Snow shares his views, informed by more than twenty years of racing and coaching endurance sports, on how an athlete's mindset can have a profound impact on performance. In episode 5, Coach Tim delves into Coping Visualization. As we mentally prepare for race day, we so often visualize the perfect day. Perfect weather. Perfect execution. But in the world of endurance sports, a race is seldom perfect. A real race day includes uncontrollables, and how we respond (and not react) to them will be what makes or breaks the day. In this episode Coach Tim describes coping visualization and discusses how a coach can help the athlete practice various scenarios, and teach the mind how to respond on race day, even to something not practiced.

    Why Mindset Matters in Endurance Sports and How a Coach Can Help Navigate the Minefield - Episode 4 - True Goal Setting

    In this podcast series, QT2 Owner and Head Coach Tim Snow shares his views, informed by more than twenty years of racing and coaching endurance sports, on how an athlete's mindset can have a profound impact on performance. In episode 4, Coach Tim explains the differences between goals, targets and outcomes. Goals are things over which you have near total control - e.g., your hydration intake. Targets are things over which you have some level of control, but not total control - e.g., race pace, power, heart rate. Outcomes things over which you have very little control, and often have to do with the performance of other people - e.g., whether you stand on the podium.

    A coach can help the athlete by remaining objective, and assisting the athlete to define his/her goals and develop strategies for how to accomplish those goals.
