Calories Burned Running: Charts by Weight, Pace & Distance

Quick Answer: Running burns roughly 100 calories per mile for a 150-lb (68 kg) adult, scaling linearly with body weight. Pace influences calorie burn less than people expect — total distance and body weight are the dominant factors.

The MET-based formula

Calories burned = METs × weight (kg) × time (hours)

Running METs by pace, per the Compendium of Physical Activities:

Calories burned per mile (the key chart)

Calories per mile (1.6 km) by body weight, averaged across moderate-pace running (9.8 METs at 6 mph):

Rule of thumb: Calories per mile ≈ 0.66 × bodyweight (lb). A 180-lb runner burns ~119 kcal/mile.

Pace matters less than you think

Doubling your pace doesn't double calorie burn at the same distance. It does dramatically increase calorie burn per unit time:

Across 5K, the calorie difference between a 37-min and 22-min effort is only ~30 calories. Run faster for fitness gains, not for big calorie wins.

Treadmill vs outdoor running

Outdoor running adds:

• Air resistance: ~5% extra calorie burn at moderate paces, more at fast paces
• Surface variation: trails and gravel raise burn 10–15%
• Temperature regulation: cold or hot weather raises burn 5–10%

To match outdoor burn on a treadmill, set the incline to 1%. At zero incline, treadmill running underestimates calorie burn by about 5%.

Hill running and trail running

Steep terrain raises calorie burn substantially. Approximate multipliers vs flat road running:

Downhill running reduces calorie burn by about 10–15% compared to flat — but is harder on joints. Most trail running averages ~1.3× because uphills cost more than downhills save.

How running affects TDEE

Adding running to your week increases TDEE by the calories burned. A 150-lb runner doing 3 miles, 4 days a week:

• Per session: 300 kcal
• Per week: 1,200 kcal
• Per month: ~5,200 kcal (≈ 1.5 lb of fat at maintenance)

But TDEE doesn't simply increase by exactly that amount because:

1. Compensation: Some runners eat back 50–80% of running calories without realizing
2. NEAT reduction: Hard training days often reduce non-exercise activity 100–200 kcal
3. EPOC: After-burn from running is small (~5–10% of session calories)

Net effect: running 3×/week typically raises real-world TDEE by 60–80% of the calculated burn — still substantial but not 100%.

Running for weight loss

Combine running with a modest deficit, not as the deficit itself:

The classic mistake: running hard, eating without restraint, expecting weight loss. Without a calorie deficit, even 30 miles a week often only nets 0.25 lb/week.

Running calorie tracking accuracy

Watches overestimate running calories more often than they underestimate. Add 200 calories of buffer if you plan to eat back what your watch shows.

Frequently asked questions

How many calories does running 1 mile burn?

About 100 kcal for a 150-lb adult, scaling roughly with body weight. The formula: 0.66 × your weight in lb = calories per mile.

Is running good for weight loss?

Yes, but only when paired with a calorie deficit. Running raises TDEE and protects against muscle loss while cutting, but does not by itself create a deficit unless eating remains controlled.

How long should I run to lose 1 lb?

A 1-lb fat loss requires a ~3,500 kcal deficit. At 100 kcal/mile, that's 35 miles of running with no compensation. In practice plan on 50+ miles to net 1 lb purely from running.

Does running burn fat or muscle?

Steady-state running primarily burns fat once glycogen is depleted (typically 30+ min into the run). Long, slow runs preferentially burn fat; sprints burn glycogen. Both are fine for weight management.

Should I run on an empty stomach?

For runs under 60 minutes, fed or fasted both work. For longer runs (90+ min), eat 300–500 kcal of carbs 2–3 hours before to support performance.
