walk/run

331 kcal / hour Walk/run burns approximately 331 calories per hour for a 70 kg (154 lb) adult, and 165 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 236 to 567 kcal.

It carries a MET value of 4.5 in the 2024 Adult Compendium of Physical Activities, which lists 2 measured variations of this activity from MET 4 to 5.

Calories burned walk/run by body weight

Energy cost scales with the mass you move, so body weight changes the answer more than anything else.

Every official intensity of walk/run

The Compendium lists 2 separate walk/run entries, each with its own measured MET value — from 4 to 5. Most calculators collapse all of this into one number. Pick the row that matches what you actually did.

Codes are 2024 Adult Compendium activity codes. A dash means the code could not be read unambiguously from the published table, so it is left blank rather than guessed — the MET value and description are unaffected.

What 331 calories an hour actually means

At MET 4.5, walk/run counts as moderate activity — it uses about 4.5 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 6 kcal per minute, or 331 kcal across a full hour.

Within home repair, that ranks 8th of 26 activities by energy cost, a little below caulking (MET 4.75) and above automobile body work (MET 4).

Put differently: one hour of walk/run costs about the same energy as 68 minutes of ordinary walking.

On the food side, a plain bagel (about 245 kcal) takes roughly 44 minutes of walk/run to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.

Questions

How many calories does walk/run burn per hour?

About 331 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 4.5. A 90 kg adult burns closer to 425 kcal in the same hour, because energy cost scales almost directly with body mass.

How many calories does 30 minutes of walk/run burn?

Roughly 165 kcal at 70 kg, 142 kcal at 60 kg and 236 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.

What is the MET value of walk/run?

4.5, taken as the median of the 2 walk/run entries in the 2024 Adult Compendium, which range from 4 to 5 depending on intensity. One MET is the energy you use sitting quietly, so MET 4.5 means 4.5 times that rate.

Is this an exact number of calories?

No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.
