Running burns more calories per minute than walking. But walking covers the same distance more safely and with less injury risk. Whether walking or running is "better" depends on what you're comparing — time or distance — and what your goals are.
Calories burned: walking vs running per mile
When comparing the same distance, walking and running burn surprisingly similar calories. This surprises most people.
| Body weight | Walking 1 mile (~20 min) | Running 1 mile (~10 min) |
|---|---|---|
| 9 stone (57kg) | ~65 kcal | ~80 kcal |
| 11 stone (70kg) | ~80 kcal | ~100 kcal |
| 13 stone (83kg) | ~95 kcal | ~120 kcal |
| 15 stone (95kg) | ~110 kcal | ~135 kcal |
Calories burned: walking vs running per 30 minutes
When you compare the same time, running burns dramatically more — because you cover more distance in the same window.
| Body weight | Brisk walking (30 min, ~3.5mph) | Running (30 min, ~6mph) |
|---|---|---|
| 9 stone (57kg) | ~120 kcal | ~250 kcal |
| 11 stone (70kg) | ~150 kcal | ~300 kcal |
| 13 stone (83kg) | ~175 kcal | ~350 kcal |
| 15 stone (95kg) | ~200 kcal | ~400 kcal |
Which is better for weight loss?
Running wins on calorie burn per unit of time — but consistency wins over intensity for most people. The best exercise for weight loss is the one you actually do regularly.
Running has significantly higher injury rates than walking. Common running injuries — shin splints, knee pain, plantar fasciitis — frequently sideline people for weeks. A month off running eliminates all those calorie-burn advantages. Walking, by contrast, has very low injury rates and can typically be done daily regardless of age or fitness level.
The practical comparison for most UK adults
- If you can run without injury → running burns more per minute, is time-efficient, useful if you're limited on time
- If you're new to exercise, returning from injury, or have joint issues → walking is safer, more sustainable, and still very effective over time
- If you enjoy both → alternating (running some days, walking others) gives the calorie benefits of running with the recovery benefits of walking
The afterburn effect: does running burn more calories after exercise?
Running at moderate-to-high intensity produces a meaningful EPOC (Excess Post-exercise Oxygen Consumption) effect — your metabolism stays elevated for 2–4 hours after a run, burning additional calories beyond what you tracked during the session. This adds roughly 10–15% to the total calorie burn.
Brisk walking produces a smaller EPOC effect — perhaps 5–7% additional post-exercise burn. This is a real advantage for running, but it's smaller than fitness marketing often implies.
Walking vs running: other health considerations
| Factor | Walking | Running |
|---|---|---|
| Injury risk | Low | Moderate–high |
| Joint impact | Low | High (2–3× body weight) |
| Cardiovascular benefit | Significant | Greater per minute |
| Suitable for beginners | Yes | Build up gradually |
| Calories per minute | Lower | Higher |
| Calories per mile | Similar | ~20% more |
| Sustainability | High — can do daily | Recovery days needed |
