Walking vs Running for Weight Loss: Calories, Time and Injury Risk (and How to Track It in Suu)

Published: · Furkan Mert Fındıklı · 7 min read

Short answer: Both work for weight loss; the difference is time and how long you can keep it up. Minute for minute, running burns roughly 2.5–3 times what walking does, but over the same distance only about 40% more. Short on time and your joints are fine? Running is more efficient. New to exercise or carrying extra weight? Start by walking and add running intervals gradually. Suu records both with GPS.

We wrote this guide as the two-person team that builds Suu. We recommend our app, but the advice rests on the World Health Organization, the NHS and peer-reviewed studies — you can follow the same steps without Suu.

The question usually comes as: “An hour's walk or a 30-minute run?” The short answer is that both help you lose weight — just not in the same way. Running burns far more energy per minute; walking is easier to keep up for longer and carries a lower injury risk.

Below we put the numbers side by side: calories over the same time and the same distance, whether the post-run 'afterburn' is real, what happens to appetite, and who should start with which.

Same distance or same time? That's where the difference is

A common belief is that a kilometre costs the same calories whether you walk or run it. Measurements don't back that up: in a study of 24 people, running 1,600 metres used about 115 kcal and walking the same distance about 81 kcal — roughly 40% more for running over the same distance.2

The real gap is time. In the same study the running speed (about 10 km/h) was double the walking speed (about 5 km/h). Using those averages, 30 minutes of brisk walking comes to roughly 130 kcal and 30 minutes of running to roughly 360 kcal. Your numbers depend on your weight and pace, but the ratio stays similar.

There's no hours-long 'fat burn' after a run. In 30 people averaging 71 kg, metabolism was back to resting 10 minutes after walking and 15 minutes after running; total energy for 1,600 metres including recovery was about 111 kcal walking and about 159 kcal running.3

What we know about weight loss and health

A large study that followed 15,237 walkers and 32,216 runners for 6.2 years found that, per unit of energy spent, running was linked with more weight loss than walking — about 90% more in the heaviest group.4 Because it's observational, other habits of people who choose to run may play a part.

For health the picture is even: for the same energy spent, walking and running cut the risk of high blood pressure, high cholesterol and diabetes by similar amounts.5 The World Health Organization's advice reflects this: 150–300 minutes of moderate or 75–150 minutes of vigorous activity a week.1 Roughly, one minute of running stands in for two minutes of walking.

Appetite and injuries: two things people forget

In a small study, women ate about 194 kcal less than they had burned at the meal after a 60-minute run, while those who walked for the same time ate 41 kcal more than they had burned.7 One study doesn't make a rule, but it's a reminder that an 'I earned it' snack after a walk can easily cancel what you burned.

Then there's injury: novice runners have about 17.8 injuries per 1,000 hours of running, compared with 7.7 in recreational runners who run regularly.6 Running's risk is highest in the first months — and three weeks off with an injury costs far more calories than walking every day.

Which to start with? A practical plan

If your time, joints and fitness allow, running is more efficient per minute. If you're new, carrying significant extra weight or have knee problems, walking is the safer start. For most people the best option is a mix:

  • Weeks 1–2: brisk 30-minute walks 3–5 days a week — you can talk but not sing. That's the start of the NHS goal of at least 150 minutes of moderate activity a week.8
  • Weeks 3–6: add intervals of 1 minute easy running and 2 minutes walking; increase the running minutes a little each week.
  • After that: once you can run 20–30 minutes non-stop, run 2–3 days a week and walk on the others.
  • Pain rule: if pain hasn't gone by the next day, take a step back.
  • Don't forget your plate: what you eat still decides weight loss; count only half of what you burn as 'available to eat back'.

Where to track this in Suu

Menu names are exactly as they appear in the app:

  1. Record your walk or run with GPS

    Home → quick add → Add Exercise → Walking or Running → start

    Time, distance, pace, route and calories burned are recorded live; record the same route walking and running and see the difference yourself. Start it from Apple Watch and you'll see your heart rate live too.

  2. See your whole day on one screen

    Nutrition screen → Today

    Your calories for the day appear next to your target, and post-walk snacks are listed here with their times.

  3. Milestones and Badges

    iPhone: You tab → Exercise → Distance Milestones · Badges
    Android: The Badges screen and Milestones at the end of a workout

    Distance from runs, walks and hikes adds up into milestones you can share as certificates, so you see the move from walking to running step by step.

  4. Daily movement reminder

    iPhone: Settings → Notification Settings → Daily notifications
    Android: Settings → Daily notifications

    The “Log your movement 🚶” reminder puts your walking time on your phone.

GPS walks and runs, milestones and badges are free.

In short

Both work for weight loss. Running burns about 2.5–3 times more per minute; walking is easier to sustain, carries less injury risk and gives similar health benefits for the same energy spent.

Short on time, run; new to it, walk — and for most people the best plan is to start walking and gradually add running intervals. Whichever you choose, what decides the result is keeping it up for weeks and watching your plate.

Frequently asked questions

Is walking or running better for weight loss?

Both work. Running burns roughly 2.5–3 times more calories in the same time; walking is easier to keep up and has a lower injury risk. Short on time, run; new to exercise, walk — for most people a mix is best.

How many calories does 30 minutes of walking burn?

Using measured averages, roughly: a brisk walk at about 5 km/h burns around 130 kcal in 30 minutes, and a run at about 10 km/h around 360 kcal. Your numbers depend on your weight and pace.

Do walking and running the same distance burn the same calories?

No. In measurements, running 1,600 metres used about 115 kcal and walking it about 81 kcal — roughly 40% more for running. The bigger difference comes from running covering the distance in half the time.

Can overweight people start running?

Yes, but starting with walking is safer: novice runners have more than twice the injury rate of regular runners. After a few weeks of brisk walking add short running intervals, and check with your doctor first if you have health conditions.

Can you lose weight just by walking?

Yes, if you watch what you eat as well. Walking burns less per minute but is easy to sustain, and for the same energy spent it lowers blood pressure, cholesterol and diabetes risk about as much as running.

Do you keep burning fat after a run?

Only briefly. In measurements, metabolism returned to resting 15 minutes after running and 10 minutes after walking; the extra is tens of calories. The real difference is in the workout itself.
