How Many Calories Does Running Burn?
Running is one of the most energy-intensive forms of exercise available. The number of calories burned depends primarily on body weight and distance — a heavier person uses more energy to move the same distance. Pace has a smaller effect than most people expect: running faster burns slightly more calories per minute but finishes the distance sooner, so the net difference per kilometre is modest. The most accurate simple formula uses the MET (Metabolic Equivalent of Task) value: Calories = MET × body weight in kg × duration in hours.
MET values for running range from about 6 for a very slow jog (over 8:00 min/km) up to 14.5+ for near-maximum sprint efforts. A 70kg runner doing a moderate 5km run at 6:00 min/km for 30 minutes burns approximately 350 kcal. The same runner walking the same distance burns only around 220 kcal — running is roughly 60% more energy-intensive than walking the same route.
Calorie calculations are estimates, not exact measurements. Individual variation in running economy, body composition, terrain, wind, and heat all affect real-world energy expenditure. Use this calculator as a directional guide for planning nutrition around training.
How to Use This Calculator
Calorie Burn by Run Type (70kg runner)
- • Easy 5km jog (~35 min): ~280–320 kcal burned
- • Moderate 10km (~60 min): ~600–700 kcal burned
- • Half marathon (~2hr): ~1,400–1,600 kcal burned
- • Marathon (~4hr): ~2,600–3,000 kcal burned
- • 30-min vigorous run: ~400–480 kcal burned
Why Calorie Burn From Running Isn't the Full Weight-Loss Picture
A well-documented "compensation effect" means many people unconsciously eat somewhat more or move less throughout the rest of the day after a hard run, partially offsetting the calorie deficit the run created — this is a major, often-overlooked reason some dedicated runners see less weight change than a simple calories-burned calculation would predict.
Running's afterburn effect (EPOC — excess post-exercise oxygen consumption, extra calories burned recovering after a workout) is real but modest for typical training runs, generally adding only a small percentage on top of the exercise calories themselves — nowhere near enough to significantly change a day's total energy balance on its own, unlike the popular fitness-marketing claims sometimes suggest.
For most people, non-exercise activity (NEAT — daily movement outside structured workouts, like walking, fidgeting, and incidental activity) actually varies more day-to-day than exercise calories do, and is a bigger lever for total daily energy expenditure than most runners realise, which is worth remembering before treating a single run's calorie count as the main determinant of a day's energy balance.
?Frequently Asked Questions
Per kilometre, running faster burns very slightly more calories — but the difference is smaller than most people expect. Calorie burn is dominated by the work done against gravity (body weight × vertical movement) rather than speed. The big difference is time: running faster finishes the distance sooner, so you burn fewer calories per session unless you extend the duration. For total calorie burn in a fixed time window, faster running does burn significantly more per minute.
