S2 E25: The VO₂ Max Sweet Spot: Finding Your Perfect Intensity

Are you getting the most out of your high-intensity intervals, or are you going too hard? In this episode of Race Ready, Andy Newell and Brian Halligan dive into the science and execution of L4 training, VO₂ max development, and the fine line between productive intensity and unnecessary fatigue. They break down why harder isn't always better, how to pace intervals to maximize time at the right intensity, and why finishing a workout completely exhausted doesn't necessarily mean you've made the biggest training gains.

The conversation explores different approaches to interval training, including hard-start intervals, steady pacing, recovery periods, and the challenges of translating laboratory research into real-world skiing. Andy and Brian discuss how terrain, workout duration, and intensity distribution influence the effectiveness of a session. They also examine lessons from elite athletes like Gus Schumacher, including the importance of managing training volume, maintaining technical quality, and recognizing when additional training may be doing more harm than good.

Beyond interval training, the episode tackles some of the toughest decisions endurance athletes face: when to push through fatigue, when to back off, and how to approach training during and after illness. Andy and Brian also answer listener questions about recovery between intervals, training with limited time, and preparing for major events like the Birkie. Whether you're an elite skier, a masters athlete, or a coach looking to make every session count, this episode offers practical insights into training with greater purpose and getting faster without simply training harder.
