🔥 Want to train smarter and avoid common mistakes? This episode covers how to actually set your running zones — without falling into data traps or overtraining.

🎙️ This week, Coach Zoë shares insights from her VO2 max and lactate threshold lab test — and what it revealed about the accuracy of smartwatches, heart rate zones, and perceived effort. She and TJ break down:

Why most athletes are using flawed training zones
What "zone 2" really means — and why your easy days might not be easy enough
The science of threshold, VO2 max, and how to test them (with or without a lab)
The biggest mistakes athletes make with heart rate and watch-generated zones
What effort-based training actually looks like in practice
