The numbers behind my climbing test.
I built a climbing test that tells a mountain biker exactly why they’re slow on climbs. Then I took it myself. Three findings:
1. My VO2max ceiling — my 5-minute power — barely sits above my 20-minute threshold. 3.9 vs 3.8 W/kg. Three percent apart. Ceiling’s too low.
2. Good peak power, rusty sprints. 100% → 82% → 93% across five 1-minute reps. Repeatability is a skill and I haven’t been practicing it.
3. I fade 18% late in rides.
None of it needs an e-bike. The method works for anyone: test, find the limiter, train the limiter, retest.
Follow along — the training plan and the retest are coming.
