Your fancy smartwatch is lying to you about your VO2 max, and chasing that number is sabotaging your race times

Most runners obsess over VO₂ max, but few really understand what it means or how to use it. In this episode, I break down the truth about what VO₂ max actually measures, why your watch might be misleading you, and how to train in a way that builds lasting fitness. If you’ve ever wondered why your numbers don’t match how strong you feel, or how to make sense of VO₂ workouts without burning out, this conversation will give you the clarity and tools to get there.

Key Takeaways

1. VO2 max shows your genetic potential for using oxygen, but having a high number doesn't guarantee fast race times.
2. Smartwatches often give inaccurate VO₂ max numbers because they can’t measure things like sleep, recovery, or stress.
3. The right workouts and patience can help you train smarter, improve steadily, and unlock real race-day performance.
