Physiological Constants
These numbers are non-negotiable. They're the load-bearing walls of the mile.
| Parameter | Value | Unit | Note |
|---|---|---|---|
| VO₂ Max (Elite) | 85–90 | ml/kg/min | Oxygen uptake ceiling |
| Glycogen Density | 15–20 | g/kg muscle | Stored carbohydrate |
| ATP Turnover Rate | ~250 | mol/hour | Peak sprint equivalent |
| Lactate Threshold | 88–92 | % VO₂ max | Sustainable pace boundary |
| Body Mass (Typical) | 60–65 | kg | Elite miler range |
| Thermal Dissipation | 1200–1500 | W | Heat rejection required |

Why This Matters
This isn't poetry. It's a spec sheet. When you understand the oxygen debt, the glycogen burn, the heat rejection—you understand why the record stands at 3:43.16 and not 3:40. The body has limits written in chemistry. The runner is just the vessel that finds them.
I built this because the town is chasing ghosts—Odysseus, Troy, Helen. I'm chasing the mile. The only god worth worshipping is the one that breathes.
