How many calories does running burn?
Estimate your energy expenditure in seconds from your weight and the distance you ran. The formula is transparent and pace is only optional, because over the same distance it barely changes the total. You also get the MET-based reading.
Net expenditure is calculated as kcal = weight (kg) × distance (km) × 1.036, a robust approximation because the energy cost per kilometer barely changes with pace. The MET method (kcal = MET × weight × duration) depends on time spent and gives a similar ballpark. These values are estimates: they don’t replace an individual measurement.
How to calculate the calories you burn running
When you run, the energy you burn depends above all on two things: the weight you carry and the distance you cover. The energy cost of moving forward one mile barely changes with speed, which allows a simple, robust formula for net expenditure (the energy truly attributable to the run):
Worked example: for a 155 lb runner over a 10K (6.2 mi), 0.756 × 155 × 6.2 ≈ 725 kcal. Per mile, that’s about 117 kcal. Double the distance and you double the calories; weighing 20 lb more raises them by about 13% over the same distance.
The MET method (time-based)
Another approach uses the MET (metabolic equivalent), which measures intensity relative to rest. Running is worth about 8 to 12 METs depending on pace: around 8 METs for an easy jog, up to 11 or 12 at a sustained effort. Energy expenditure is then calculated from time spent:
Example: 155 lb (70 kg), 1 hour of running at 6.2 mph (about 10 METs) gives 10 × 70 × 1 = 700 kcal. That’s very close to the 725 kcal from the per-distance formula, which is reassuring: the two methods agree. The pace you enter in the calculator is used precisely to estimate the duration and the METs for this second reading.
Whatever the method, remember these are estimates: real expenditure varies from person to person with terrain, wind, running economy and individual metabolism.
Chart: calories by weight and distance
Estimated net expenditure (in kcal) by body weight and distance, using the weight × distance × 1.036 formula. Values are rounded to the nearest calorie.
| Weight | 1 mile | 5K | 10K | Half | Marathon |
|---|---|---|---|---|---|
| 110 lb | 83 kcal | 258 kcal | 517 kcal | 1,091 kcal | 2,181 kcal |
| 130 lb | 98 kcal | 305 kcal | 611 kcal | 1,289 kcal | 2,578 kcal |
| 150 lb | 113 kcal | 352 kcal | 705 kcal | 1,487 kcal | 2,974 kcal |
| 170 lb | 129 kcal | 399 kcal | 799 kcal | 1,685 kcal | 3,371 kcal |
| 190 lb | 144 kcal | 446 kcal | 893 kcal | 1,884 kcal | 3,767 kcal |
| 210 lb | 159 kcal | 493 kcal | 987 kcal | 2,082 kcal | 4,164 kcal |
| 230 lb | 174 kcal | 540 kcal | 1,081 kcal | 2,280 kcal | 4,561 kcal |
These figures are net expenditure (the extra energy due to running). Gross expenditure, which includes your resting metabolism, is slightly higher. The calculator above personalizes the result with your exact weight and distance.
Frequently asked questions
How many calories do you burn running a mile?
As a first approximation, about 0.76 kcal per pound of body weight per mile (1.036 kcal per kg per km, for net expenditure). A 155 lb runner therefore burns about 117 kcal per mile, or around 725 kcal over a 10K. The figure depends mainly on your weight and the distance, much less on your pace.
Does pace change the number of calories burned?
Surprisingly little, over the same distance. The energy cost per mile of running is almost constant: running 6 miles fast or slow burns a similar number of calories, just spread over a different amount of time. Running fast burns more calories per minute, but since you run for less time over the same distance, the total per mile stays close. That’s why the main formula only uses weight and distance.
What’s the difference between net and gross calories?
Gross expenditure counts all the energy used during the run, resting metabolism included. Net expenditure subtracts what you would have burned at rest over the same time: it’s the real extra due to running, and it’s what matters for an energy balance. This calculator shows net expenditure (1.036 coefficient), closer to the energy actually attributable to the effort.
What is the MET method, and what is running worth?
The MET (metabolic equivalent) expresses an activity’s intensity relative to rest: 1 MET is your metabolism sitting quietly. Running is worth about 8 to 12 METs depending on pace (from an easy jog to a sustained effort). Expenditure is then calculated as kcal = MET × weight (kg) × duration (hours). It’s a time-based method that complements the per-distance formula.
Are these calories enough to lose weight?
Running clearly raises your energy expenditure, but weight loss depends on your overall balance across the day: what you burn and what you eat. This calculator’s estimates give a reliable ballpark for the energy running costs; for a weight goal, it’s better to combine them with tracking your food than to try to “burn off” a meal right away.
