45 minutes of running burns 410–720 calories. Full weight-based table with pacing strategy and recovery tips.
Running for 45 minutes at moderate pace burns approximately 410–720 calories — a sweet spot between a quick jog and a full hour-long run.
Forty-five minutes is a popular training duration that covers roughly 4.5 miles (7.2 km) at a 6 mph pace. This duration is long enough to provide substantial cardiovascular training and trigger meaningful fat oxidation, yet short enough to allow recovery for the next day's workout. Many half-marathon training plans use 45-minute runs as their midweek standard session.
A 45-minute run burns about 50% more than cycling for the same duration and roughly 2.5 times more than walking. Compared to swimming, running edges ahead by about 15–20% in calories per minute at moderate intensities.
If you can run comfortably for 45 minutes, three sessions per week provide 1,230–2,160 calories of exercise burn. This is one of the most effective combinations of time investment and calorie output for weight management, rivaling much longer walking or cycling sessions.
Direct answer: 45 minutes of running burns an estimated 412–725 calories, depending on body weight (180 lb / 82 kg: ~572 kcal). Intensity assumed: Moderate (6 mph, 10 min/mile) (MET 9.3). This is an estimate, not a measurement.
| Body weight | Calories burned |
|---|---|
| 130 lb (59 kg) | ~412 cal |
| 155 lb (70 kg) | ~488 cal |
| 180 lb (82 kg) | ~572 cal |
| 205 lb (93 kg) | ~649 cal |
| 230 lb (104 kg) | ~725 cal |
Example: At MET 9.3, a 180 lb (82 kg) person doing 45 minutes of running burns approximately 572 calories: 9.3 × 82 × 0.75 h ≈ 572 kcal.
There is no single universal calorie figure for this activity. At 180 lb (82 kg) and the same 45 minutes:
| Style / effort | MET | Estimate |
|---|---|---|
| Jogging (5 mph, 12 min/mile) | 8.5 | ~523 cal |
| Fast (7 mph, 8.5 min/mile) | 11 | ~677 cal |
| Very fast (8 mph, 7.5 min/mile) | 12 | ~738 cal |
| Race pace (10 mph, 6 min/mile) | 14.8 | ~910 cal |
An estimated 412–725 calories, depending on body weight. A 180 lb (82 kg) person burns about 572 kcal, calculated as MET 9.3 × 82 kg × 0.75 hours.
About 12.7 kcal per minute for a 180 lb (82 kg) person, or 7.0 kcal per kilogram of body weight across the whole session.
Because the MET formula scales directly with body mass: a 130 lb person burns about 412 kcal here versus 725 kcal for a 230 lb person — a 76% spread for the identical session.
From the 2024 Adult Compendium of Physical Activities, the reference database of measured MET intensities for physical activities. Every figure on this page uses that value in the formula Calories = MET × body weight (kg) × duration (hours).
They are estimates from population averages, not measurements. Individual results commonly land within about ±15% of the figure shown; actual intensity and pace, body composition and fitness, terrain and technique all shift the real number. The values are gross calories, so they include the energy you would have burned at rest.
