Zone 2 training is the missing link for most masters runners.
If you’re over 40 and trying to run faster, recover better, and stay injury-free, building a strong aerobic base is essential. In this episode of Masters On The Move, we break down the science of Zone 2 running, why it matters more as we age, and how to apply it correctly in your training.
Many runners spend too much time in the “grey zone” — running too hard on easy days and not recovering properly. The result? Fatigue, plateaued performance, and recurring injuries.
In this episode you’ll learn:
✔ What Zone 2 training actually is
✔ How to know if you’re truly in Zone 2
✔ The science behind mitochondrial development and aerobic adaptation
✔ Why aerobic base training is crucial for runners over 40
✔ How much Zone 2 running masters athletes should be doing
✔ How Zone 2 supports interval training and 5K performance
✔ How to run faster after 40 without burning out
We also cover how Zone 2 improves fat oxidation, metabolic health, nervous system balance, and recovery — making it one of the most powerful tools for endurance training longevity.
Whether you’re training for a faster 5K, 10K, half marathon, or simply want to keep running strong into your 50s and 60s, this episode gives you a practical, science-based framework for smarter training.
If you’re a masters runner looking to improve endurance, avoid injury, and build long-term performance, this episode is for you.
