ランニングパワー計算機 – ワット・W/kg
ペース・体重・傾斜からランニングパワー（ワット）を推定。Minettiのエネルギーコスト方程式に基づく。
💡 ご存知でしたか？
- Running power meters only became commercially available around 2015 — roughly 30 years after cycling power meters transformed competitive cycling.
- Elite runners typically produce 3–5 watts per kilogram of body weight while racing; untrained runners are closer to 2–3 W/kg.
- Running uphill at the same power output as flat running is more efficient in terms of pace-per-effort — a key insight for pacing hilly races.
