In this episode, we unpack one of running’s most misunderstood topics—fatigue—and set the record straight on lactate with exercise physiologist and Coach Parry coach Ntutu Letseka.
You’ll learn what actually drives that burning sensation, how the brain (the central governor) paces you, and the practical training/recovery moves that boost performance—especially for female runners 45+.
What you’ll learn:
- Lactic acid vs. lactate: why lactate is a fuel and not the villain
- Energy systems 101: ATP, glycolysis, aerobic metabolism & where fatigue really comes from
- The brain’s role: how the central governor protects you (and why you can still sprint at the end)
- Lactate thresholds (LT1 & LT2): what they mean and how they predict performance
- Training that works: build an aerobic base, then add smart threshold work (cruise intervals, controlled tempos)
- Recovery that sticks: fueling, sleep, cool-downs & truly easy active recovery (what counts—and what doesn’t)
