Your VO₂ Max Workouts Aren't Working (Here's What Actually Does)

That 4×4 session leaving you wrecked? It's accumulating 2–3 minutes of actual VO₂ max stimulus. Here's the format that delivers 15–18 minutes — same time on your feet.

Nutrition 10 May 2025

What to Eat During Your Run or Ride (And Why You're Probably Eating Too Little)

Most athletes think fueling during training is only for races. That thinking is costing you — in training quality, recovery, and how you feel.

The method

Not a guess. A physiological model.

Every session is built on peer-reviewed exercise physiology — whether you're training for a 5K, a half marathon, or a full. Intervals are calculated from your lactate threshold. Long runs target aerobic fat-oxidation zones. Recovery is a stimulus, not a skip day.

01 / INTERVALS

VO₂ Max Development

Short, high-intensity efforts at 95–100% of maximum aerobic velocity. Designed to raise your oxygen ceiling — the single biggest predictor of performance.

02 / TEMPO

Lactate Threshold Training

Sustained efforts just below the lactate threshold shift the curve — so your body clears lactic acid faster, keeping you fast for longer at race pace.

03 / LONG RUN

Aerobic Base Building

Easy-to-moderate long runs expand mitochondrial density and fat oxidation capacity. The invisible engine that makes everything else possible.
