Frequently asked questions
- Does pace affect calories burned running?
- Surprisingly little — the energy cost per km is almost constant across typical running speeds. Running faster gets you to the same calorie total in less time; pace mainly affects rate, not total cost per km.
- Why does heavier weight mean more calories?
- More mass requires more mechanical work to lift and propel with each stride. A 90 kg runner burns roughly 30% more per km than a 70 kg runner at the same pace.
