Calories Burned Running at 7 mph at 55 kg — 605 kcal per Hour
Running at 7 mph at 55 kg (110-132 lb) burns about 605 kcal per hour. That figure comes from the activity's MET value of 11 in the 2011 Compendium of Physical Activities, multiplied by body weight: 11 x 55 kg x 1 hour = 605 kcal. This page works the numbers out in full - for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight - so you can plan sessions with real figures instead of guessing.
Running at 7 mph (11.3 km/h) is a brisk run — an 8 minute 34 second mile, or about 5 minutes 19 seconds per kilometre. You cover 7 miles in an hour, your breathing is hard, and talking is limited to a word or two at a time. For many runners this is tempo pace: the speed of a hard training run or a fast 10k, not a comfortable jog.
Running at 7 mph suits experienced runners, tempo-run training, and racers chasing a faster 5k or 10k. The headline number to remember is 605 kcal per hour at 55 kg, or about 302 kcal for a 30-minute run. Everything below is an estimate: MET values are population averages, and your own burn will vary with fitness, running economy and conditions. That does not make the numbers useless — it makes them a planning tool, and a good one, as long as you treat them as approximate.
Calculate your own numbers
Use the running calorie calculator to work out your own burn for running at 7 mph at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. You can also try the calorie calculator to see how this session fits into your total daily energy use.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575-1581):
Calories (kcal) = MET x body weight (kg) x duration (hours)
One MET is the energy you use sitting quietly at rest - about 1 kcal per kilogram of body weight per hour. An activity rated at 11 METs therefore uses 11 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The value used here, 11, is the one recorded for running at 7 mph in the FitCalc activity data.
Worked through for this page:
- MET for running at 7 mph: 11
- Body weight: 55 kg (the midpoint of the 50-60 kg band, 110-132 lb)
- Duration: 1 hour
- Calculation: 11 x 55 x 1 = 605 kcal
For a 30-minute session the same calculation is 11 x 55 x 0.5 = 302 kcal. Nothing else is hidden in the maths - if your weight or duration changes, only those two numbers change.
Your numbers at 55 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 11 x 55 x 0.25 | 151 kcal |
| 30 minutes | 11 x 55 x 0.5 | 302 kcal |
| 45 minutes | 11 x 55 x 0.75 | 454 kcal |
| 60 minutes | 11 x 55 x 1 | 605 kcal |
| 90 minutes | 11 x 55 x 1.5 | 908 kcal |
That is about 10.1 kcal per minute of running at 7 mph at this weight. A short session still counts: even 15 minutes burns 151 kcal, and three 15-minute sessions across a day add up to the same 454 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same - it describes the activity, not the person - but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 605 kcal | 302 kcal |
| 65 kg | 715 kcal | 358 kcal |
| 75 kg | 825 kcal | 412 kcal |
| 85 kg | 935 kcal | 468 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected - it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How running at 7 mph compares
Here is running at 7 mph against four other activities at the same 55 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 55 kg |
|---|---|---|
| running at 7 mph | 11 | 605 kcal |
| running at 6 mph | 9.8 | 539 kcal |
| running at 5 mph | 8.3 | 457 kcal |
| climbing stairs | 8.8 | 484 kcal |
| running at 8 mph | 11.8 | 649 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week - one harder session, two easier ones - is usually more sustainable than doing the hardest activity every time.
Fitting running at 7 mph into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 604 kcal | 1210 kcal |
| 3 sessions | 906 kcal | 1815 kcal |
| 5 sessions | 1510 kcal | 3025 kcal |
At 11.0 METs, running at 7 mph is vigorous-intensity activity, so it counts double toward the widely used adult activity target: 75 minutes of vigorous activity a week is the equivalent of 150 minutes of moderate activity. Two 30-minute tempo runs a week already give you 60 vigorous minutes and burn about 604 kcal a week at 55 kg. Because this pace is demanding, it works best as one or two sessions a week inside a broader mix of slower runs and rest days — not as an everyday pace.
How to use the result
Warm up properly: ten minutes of easy jogging or brisk walking before you hold 7 mph, because this pace asks a lot of cold muscles. Keep your form tall and relaxed — tension in the shoulders and hands wastes energy at speed — and drive your arms front to back rather than across your body. Use this pace for tempo runs of 20-30 minutes rather than for every run: most of your weekly miles should still be slower, with one faster session a week. Cool down with five to ten minutes of easy jogging or walking, and keep a rest or easy day after a hard tempo session. If your breathing becomes ragged or your form falls apart, slow down: holding good form at 6 mph beats struggling at 7 mph. Use the numbers on this page to set realistic expectations rather than to chase a daily total. If you are tracking food as well, add the session's calories to your total daily energy expenditure for that day, and remember that the figure is an estimate with roughly 10-20% uncertainty. Do not eat back every calorie the calculator shows: activity trackers and MET estimates both tend to overstate slightly, and a small margin keeps a weight-loss plan on track. If you are aiming to lose weight, keep the deficit modest - 300-500 kcal a day is a common, sustainable range - and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise.
What the number does NOT tell you
The MET formula is honest about what it measures and silent about the rest. It assumes steady running on level ground at 7 mph, so it does not account for hills, wind, heat, or the surface underfoot — all of which change the real figure. It does not account for your running economy: experienced runners burn fewer calories at the same speed than beginners, because their bodies are more efficient, and economy varies more at faster speeds. It does not account for body composition, it does not include the afterburn that follows hard sessions, and it says nothing about fitness, strength or bone density gained. It also cannot tell you whether running is safe for you: if you have a heart condition, joint problems, asthma or any other health concern, check with a healthcare professional before starting a new, intense activity. Use the calorie figure as a planning estimate, and judge the run by how you feel doing it and whether you keep doing it.
Frequently asked questions
How many calories do I burn running at 7 mph for 30 minutes at 55 kg?
About 302 kcal. The maths is 11 METs x 55 kg x 0.5 hours = 302 kcal. That is an estimate from the Compendium average — your real burn depends on your fitness, your running economy and the terrain. If you weigh more or less than 55 kg, use the weight table above to read your own figure.
How long does it take to run 5k at 7 mph?
About 27 minutes. Five kilometres at 11.27 km/h takes 5 divided by 11.27 hours, which is roughly 27 minutes. That is a fast 5k time for a club runner. The pace calculator works out exact times for any distance and speed.
How many calories do I burn running at 7 mph per mile?
About 86 kcal per mile at 55 kg. A mile at 7 mph takes about 8 minutes 34 seconds, so the maths is 11 METs x 55 kg x roughly 0.143 hours. Faster running burns more per mile as well as per hour, because the MET value rises with speed — which is why a fast 5k costs more energy than a slow one.
How does running at 7 mph compare with running at 6 mph?
At 55 kg, running at 7 mph burns about 605 kcal per hour against 539 kcal at 6 mph — roughly 12% more. The extra mile per hour costs real energy: the MET value rises from 9.8 to 11.0. If you can only hold 7 mph for part of a run, mix it in as intervals rather than forcing the whole run at that pace.
Can running at 7 mph help with weight loss?
It can help, but only as part of an overall calorie deficit. At 55 kg, an hour burns about 605 kcal, which is a very strong contribution — more than the energy in a full meal — but weight loss still comes from the total balance of food and activity across the week, not from one run. Aim for a gradual loss of 0.5-1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men - consult a healthcare professional before a very-low-calorie diet.
