Endurance & Hybrid Training
Zone 2 without the mysticism, fuelling without the guesswork, and the truth about the interference effect.
Endurance training has acquired a vocabulary — zone 2, polarised, threshold, lactate — that obscures a fairly simple set of findings: most training should be easy, some should be genuinely hard, and the middle is where amateurs get stuck.
Fuelling is the other half, and it is where the largest practical gains for amateur endurance athletes still sit. These pages cover both, plus the concurrent-training question that anyone doing Hyrox-style hybrid work needs answered.

What the intensity-distribution research actually found, why "zone 2" means different things to different people, and how to set your easy pace without a lab.
- Hybrid Training: Does Lifting Ruin Your Running?
The interference effect is real, smaller than its reputation, and mostly a question of modality and scheduling.
