Calories Burned Running at 5 mph at 65 kg — 540 kcal per Hour
Running at 5 mph at 65 kg (132-154 lb) burns about 540 kcal per hour. That figure comes from the activity's MET value of 8.3 in the 2011 Compendium of Physical Activities, multiplied by body weight: 8.3 x 65 kg x 1 hour = 540 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 5 mph (8 km/h) is a gentle jog — a 12-minute mile, or about 7 minutes 27 seconds per kilometre. You cover 5 miles in an hour, you can still talk in short sentences, and for many runners this is the comfortable, conversational pace where long runs happen. It is the slowest running speed in the Compendium, and the natural starting point for new runners.
Running at 5 mph suits beginners, long slow distance runs, and recovery runs for experienced runners. The headline number to remember is 540 kcal per hour at 65 kg, or about 270 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 5 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 8.3 METs therefore uses 8.3 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, 8.3, is the one recorded for running at 5 mph in the FitCalc activity data.
Worked through for this page:
- MET for running at 5 mph: 8.3
- Body weight: 65 kg (the midpoint of the 60-70 kg band, 132-154 lb)
- Duration: 1 hour
- Calculation: 8.3 x 65 x 1 = 540 kcal
For a 30-minute session the same calculation is 8.3 x 65 x 0.5 = 270 kcal. Nothing else is hidden in the maths - if your weight or duration changes, only those two numbers change.
Your numbers at 65 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 8.3 x 65 x 0.25 | 135 kcal |
| 30 minutes | 8.3 x 65 x 0.5 | 270 kcal |
| 45 minutes | 8.3 x 65 x 0.75 | 405 kcal |
| 60 minutes | 8.3 x 65 x 1 | 540 kcal |
| 90 minutes | 8.3 x 65 x 1.5 | 809 kcal |
That is about 9.0 kcal per minute of running at 5 mph at this weight. A short session still counts: even 15 minutes burns 135 kcal, and three 15-minute sessions across a day add up to the same 405 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 | 457 kcal | 228 kcal |
| 65 kg | 540 kcal | 270 kcal |
| 75 kg | 622 kcal | 311 kcal |
| 85 kg | 706 kcal | 353 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 5 mph compares
Here is running at 5 mph against four other activities at the same 65 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 65 kg |
|---|---|---|
| running at 5 mph | 8.3 | 540 kcal |
| running at 6 mph | 9.8 | 637 kcal |
| climbing stairs | 8.8 | 572 kcal |
| hiking with a backpack | 7.3 | 474 kcal |
| walking very briskly (4.5 mph) | 7 | 455 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 5 mph into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 540 kcal | 1080 kcal |
| 3 sessions | 810 kcal | 1620 kcal |
| 5 sessions | 1350 kcal | 2700 kcal |
At 8.3 METs, running at 5 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. Three 30-minute runs a week give you 90 vigorous minutes — more than the target — and burn about 810 kcal a week at 65 kg. Keep at least one rest day between runs while you are building up, and add no more than 10% to your weekly running time at a time.
How to use the result
Warm up with five minutes of brisk walking before you start running, and finish with five minutes of walking to cool down. Keep your cadence quick and light — short, light steps are kinder to knees than long, heavy strides — and land under your body rather than reaching ahead with your foot. Breathe in a steady rhythm and keep your shoulders relaxed; tension in the upper body wastes energy. If you are new to running, use run-walk intervals — two minutes running, one minute walking, repeated — and build the running portions by a minute a week. Proper running shoes matter: get fitted at a running shop if you can, and replace shoes roughly every 500-800 km. 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 5 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. 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 5 mph for 30 minutes at 65 kg?
About 270 kcal. The maths is 8.3 METs x 65 kg x 0.5 hours = 270 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 65 kg, use the weight table above to read your own figure.
How long does it take to run 5k at 5 mph?
About 37 minutes. Five kilometres at 8 km/h takes 5 divided by 8.05 hours, which is roughly 37 minutes. That is a realistic first 5k time for a new runner, and a comfortable long-run pace for an experienced one. The pace calculator works out exact times for any distance and speed.
How does running at 5 mph compare with brisk walking?
At 65 kg, running at 5 mph burns about 540 kcal per hour against 325 kcal for brisk walking at 4 mph — roughly 66% more. Running also covers more ground: 5 miles in the hour against 4. The trade-off is impact: running loads the joints with every stride, while walking keeps one foot on the ground at all times.
Is running at 5 mph good for beginners?
Yes — it is the natural starting pace for most new runners, because it is slow enough to hold a conversation. Start with run-walk intervals rather than a continuous 30 minutes, build up gradually, keep rest days between runs, and increase weekly time by no more than 10%. If you feel sharp joint pain rather than ordinary muscle tiredness, slow down and seek advice.
Can running at 5 mph help with weight loss?
It can help, but only as part of an overall calorie deficit. At 65 kg, an hour burns about 540 kcal, which is a strong contribution — roughly 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.
