Walking vs Running
Which burns more calories, and by how much — from the same Compendium MET data.
Running burns more — about 845 kcal an hour versus 294 kcal for walking, for a 70 kg adult. That is 188% more, or 551 extra calories per hour. The gap comes from their MET values: 4 for walking against 11.5 for running.

How this is worked out
- Take the activity's MET value from the 2024 Adult Compendium of Physical Activities — the measured ratio of its energy cost to sitting quietly.
- Convert MET to a rate using the ACSM relationship: multiply by 3.5, then by body mass in kilograms, then divide by 200. That gives kilocalories per minute.
- Multiply the rate by the number of minutes actually spent.
- Round to whole kilocalories. Nothing else is applied — no age factor, no sex factor, no proprietary adjustment, because the underlying data does not support one.
kcal/min = MET × 3.5 × mass(kg) ÷ 200 kcal = kcal/min × minutes
Side by side, by body weight and duration
| Body weight | Walking · 30 min | Running · 30 min | Walking · 1 hr | Running · 1 hr |
|---|---|---|---|---|
| 50 kg | 105 | 302 | 210 | 604 |
| 60 kg | 126 | 362 | 252 | 725 |
| 70 kg | 147 | 423 | 294 | 845 |
| 80 kg | 168 | 483 | 336 | 966 |
| 90 kg | 189 | 543 | 378 | 1,087 |
| 100 kg | 210 | 604 | 420 | 1,208 |
| 110 kg | 231 | 664 | 462 | 1,328 |
| 120 kg | 252 | 725 | 504 | 1,449 |
Both columns use the same equation and the same reference data, so the comparison is like-for-like.

How to read this
A higher MET means a higher energy cost per minute — but the activity you will actually keep doing beats the one that scores better on paper. Running wins on rate; if walking is the one you enjoy, the extra 188% is easily recovered by doing 113 more minutes.
Both figures assume a 70 kg adult and steady effort for the full hour, which is a generous assumption for anything very vigorous. Realistic sessions include rest.
Questions
Does walking or running burn more calories?
Running burns more — about 845 kcal an hour versus 294 kcal for walking, for a 70 kg adult. That is 188% more, or 551 extra calories per hour. The gap comes from their MET values: 4 for walking against 11.5 for running.
Both numbers are models. Neither knows your gradient, your gear, or how hard you were actually trying.
