In this episode, we are joined by Cliff Pittman, Coaching Development Director for CTS. We take a practical look at VO₂ max and what it really means for everyday runners. We explore whether this popular performance metric is truly essential, how much it matters for trail and ultra athletes, and where it can be misunderstood or overemphasized. The conversation cuts through the numbers to focus on what actually helps runners train smarter, stay healthy, and improve long-term performance. If you've ever wondered whether your VO₂ max score is a guiding light or just another shiny data point, this episode brings clarity and perspective from the trail.
Key Topics
- What is VO2 max and why does it matter for ultra runners?
- The accuracy and limitations of wearable VO2 max estimates
- How VO2 max relates to performance, aging, and training adaptability
- The concept of fractional utilization versus maximum effort
- Strategies for incorporating VO2 max training into your season
- Cross-training options like cycling and swimming for low-impact VO2 max work
- Monitoring progress with lab versus field testing and subjective feedback
- The importance of training variety and maintaining the entire aerobic engine
- Practical workout templates: intervals, recovery, and dosage over seasons
- How strength training and muscle mass influence VO2 max
