Endurometry is a set of free running tools. The goal is simple: no more hunting for a plain pace chart inside a wall of ads.
Models used
- Riegel power law (1981): T₂ = T₁ × (D₂/D₁)^1.06
- Daniels–Gilbert: VO₂ = -4.6 + 0.182258v + 0.000104v², with the sustainable-%VO₂max curve
- ACSM running equation: VO₂ = 0.2v + 0.9v·grade + 3.5
- Karvonen heart-rate reserve: HR = (HRmax − HRrest) × intensity + HRrest
Data notes
Age factors and average finish times are currently seed data; they will be replaced with official tables and real collected data before launch.
How these numbers are produced
Each figure blends a published baseline model with real anonymous submissions using a shrinkage estimator: with few samples the value stays close to the baseline, and as submissions accumulate the real data takes over. Groups with fewer than 8 submissions show the baseline only.
