Tempo Running, VO2 Max & Tapering for HYROX World Champs | ENDUROX Podcast Ep. 2

Join Dr. Dan Plews and Dr. Adam Storey in Episode 2 of The ENDUROX Podcast. In this episode, they break down the training zones most HYROX athletes ignore, unpack the science of peaking for competition, and share what it actually takes to taper correctly for a race like World Champs.

They cover:

  • The Deadly Dozen: what it is and how it compares to HYROX as a training race
  • Dan Hoy's 57:40 at Hong Kong HYROX and why he's only scratching the surface
  • Tempo running: what it is, why HYROX athletes neglect it, and how to structure it
  • Classic tempo sessions including the 4-3-2-1 descending treadmill workout
  • VO2 max vs threshold training: the physiology, the debate, and what the research actually shows
  • Polarized training (Seiler & Stöggl) and where threshold fits in the picture
  • How training background determines when to introduce VO2 max work
  • Erg-based threshold sessions and how to use them as a complement to running
  • Six weeks out from competition: how to manage CTL, overload blocks, and taper timing
  • Competition frequency: how much racing is too much, and how to use races as training
  • Taper principles: volume, intensity, frequency, and individual psychology
  • East German vs Bulgarian taper philosophies applied to HYROX
  • Adam's PhD research on gene expression and sex differences in taper response
  • The HERITAGE Family Study: how genetics shapes your VO2 max response to training
  • Muscle fibre type, epigenetics, and the genetics of recovery
