# Kinetic · Running: sources and verification notes

All checks done **3 Oct 2026 (IST)**. "Verified" means the official page was loaded and the stated fact was read on it, unless noted otherwise. The page deliberately shows **no prices or entry fees**. Each race is linked to its organiser's site, where readers should check current dates, eligibility and fees.

## 1. Physiology (chapters, quiz, Pace & Altitude Lab)

| Claim | Basis |
|---|---|
| Energy cost of running ≈ 1 kcal per kg per km, roughly independent of speed; individual spread ±10–20% | Long-standing exercise-physiology rule of thumb (general knowledge, **not fetched**) |
| Oxygen cost ≈ 200 mL O₂ per kg per km; ≈ 5 kcal per litre of O₂ | Rule of thumb (general knowledge, **not fetched**); consistency of the two rules computed |
| Peak vertical ground reaction force ≈ 2–3 × body weight; half-sine contact model; cadence studies | Biomechanics textbook values (general knowledge, **not fetched**); worked numbers computed (impulse = weight × step time) |
| VO₂ max falls "several per cent per 1,000 m above about 1,000 m"; Lab uses 7% | **Rule of thumb, labelled as such on the page**; real losses vary between individuals |
| Energy systems (phosphocreatine, glycolysis, aerobic); glycogen ≈ 2,000 kcal; carbohydrate 30–60 g/h (up to ~90 g/h for some) | General sports-nutrition knowledge (**not fetched**) |
| Heat: ~80% of metabolic energy becomes heat; 2.4 MJ per kg of sweat evaporated; humidity limits evaporation; hyponatraemia risk | Physics + physiology textbook values (**not fetched**); worked numbers computed |
| Racing-shoe economy gains of "a few per cent for many runners" | Summary of published studies (**not fetched**); worded with the variation caveat |
| AMS, HAPE, HACE symptoms and need for descent | General high-altitude medicine knowledge (**not fetched**); the page tells readers to follow organiser and medical advice |
| ISA pressure: Leh 3,505 m ≈ 65.7 kPa (≈ 65%); Khardung La 5,370 m ≈ 51.4 kPa (≈ 51%); O₂ partial pressure = 20.95% of total | International Standard Atmosphere formula (computed) |

## 4. Left out / judgement calls

- **"Where to go" lists races, not schools.** Running has no licensing schools, so the level tabs list verified events (`.site` cards). The automated test counts unique schools **or events** for this reason.
- **Only two India body cards** (AFI and the Ladakh organiser): we found no other national body with a verifiable role in road running.
- **TMM's World Athletics label and AIMS listing** appeared in search results only, so they are not claimed on the page.
- **No coaching plans or paces as prescriptions.** The lab and chapters are illustrative; a doctor-first note for high altitude and existing conditions is in the disclaimer.
- **No prices, fees or tie-up line**; no emails or phone numbers.
- A hidden, empty `#gear` placeholder sits before the footer for a future Gear section (not built).
