20,000 Steps a Day: Miles, Calories + Benefits

Virtually every doctor or healthcare professional will tell you that the more walking you can do, the better.

While one study found that walking just 4,400 steps per day reduces the risk of death by 41% compared to walking fewer than 2,700 steps per day, the mortality risk decreases as you walk.

Therefore, walking 20000 steps per day is a fantastic workout. 

In this article, we will discuss how to walk 20000 steps a day; the calories burned walking 20000 steps a day, and tips for walking 20000 steps per day.

The Honest Truth About 20,000 Steps A Day (What The Research Actually Says About Stepping Past 10K)

Before we get into the “how many miles, how many calories” answer you came for, the more useful question is whether 20,000 steps a day is actually a better health target than 10,000 — because the step-count research over the last five years has moved the goalposts significantly, and the answer for most readers will probably surprise them. Here are the three things the evidence strongly supports before you lace up.

1. Mortality benefit mostly plateaus between 7,500 and 10,000 steps

The most-cited meta-analysis on this question — Paluch and colleagues in The Lancet Public Health (2022) — pooled 15 international cohorts covering 47,471 adults and mapped the daily-step to all-cause-mortality curve. For adults aged 60 and above, the mortality reduction curve flattened around 6,000–8,000 steps per day. For adults under 60, the curve flattened around 8,000–10,000 steps per day. Above those thresholds, additional steps produced very small incremental mortality benefit in the pooled data. Banach et al. (European Journal of Preventive Cardiology, 2023) pooled 17 cohorts of 226,889 people and reported a similar pattern, with cardiovascular-mortality benefit continuing more gradually up to roughly 12,000 steps. The widely-shared claim that “more is always better” above 10,000 steps is not strongly supported by the current evidence base. 20,000 steps a day does not appear in the mortality data as double the benefit of 10,000 — the curve has largely flattened by then.

2. Intensity matters more than raw count past ~10K

Saint-Maurice et al. (JAMA, 2020) analysed 4,840 US adults wearing accelerometers and found that cadence (steps per minute, a proxy for intensity) was not independently associated with all-cause mortality once total daily steps were accounted for — but the practical translation is that how you hit your step target still matters. A 20,000-step day accumulated at 2.5 mph shuffling pace is physiologically very different from 20,000 steps that include 60 minutes of brisk walking at 3.5–4 mph. If you are going to spend the additional 2–3 hours per day to go from 10K to 20K, the research suggests the incremental health return is much higher if you use part of that time to hit the moderate-intensity threshold (roughly 100+ steps per minute, or a brisk walking pace — see our average walking speed guide for how that translates into mph).

3. 20,000 steps has other benefits the mortality data doesn’t capture

There are two defensible reasons to aim for 20,000 steps daily even given the plateau above. First, sustained high-volume walking elicits a meaningful caloric-expenditure response in a way that 10,000 does not — if weight management is the primary goal, the 8–10 mile daily distance adds roughly 500–800 kilocalories of movement-related energy expenditure for the average adult, which is a significant lever on the calorie-balance equation. Second, the mental-health and daily-rhythm benefits of a long outdoor walking routine are well documented in the behavioural literature — a 20,000-step day often means being outdoors for 2–3 hours, and the sleep, mood, and stress-regulation benefits of that are not captured in mortality analyses. The 10,000 steps a day, 15,000 steps a day, and 5,000 steps a day guides have more on how volume scales at each tier.

When chasing 20,000 steps becomes counter-productive

Two honest cautions. First, if you are a runner training for any distance longer than a 5K, stacking 20,000 daily steps on top of a structured training block is a well-known way to dig into recovery without a matching return. At 20K steps, your connective-tissue load is non-trivial — this is where bone-stress injuries, plantar fasciitis, and Achilles tendinopathy cluster in the running injury literature. Count your run steps in the total, and if you are following one of our marathon training plans, aim for 12,000–15,000 on training days and save the 20,000 days for easy weeks. Second, if you are new to walking-as-exercise, ramping from 4,000 steps to 20,000 in a matter of weeks is the single most common cause of walking-related overuse injury we see — the American College of Sports Medicine’s rule of thumb of no more than ~10% volume increase per week applies to daily step count every bit as much as to weekly running mileage. Build up in 2,000-step steps, a fortnight at a time.

With those caveats in place, here’s exactly what walking 20,000 steps a day looks like in miles, time, and calories.

How Many Miles Is 20000 Steps?

Walking 20000 steps a day can certainly sound like a lot, especially to beginners, but how many miles are 20000 steps?

How far you will walk if you walk 20000 steps a day depends on your step length or stride length, which can be thought of as the amount of ground you cover between each step (right foot to left foot) or each stride (the distance covered by one full gait cycle, or right foot to right foot landing again).

The longer your steps and strides, the further you will walk over the course of 20000 steps.

Step length depends on numerous factors, such as your height, walking speed, sex, age, fitness level, and the terrain you’re walking on.

Of these factors, height tends to be the most significant. Taller individuals have longer legs, so they can take longer steps or strides.

You can determine your approximate step length by counting the number of steps you take over a certain distance or by wetting your feet and measuring the distance between footprints.

Alternatively, the University of Oklahoma Health Sciences Center reports that the average step length for women is approximately 26 inches, whereas the average step length for men is approximately 31 inches.

Because a mile is equal to 5,280 feet, we can determine that the average man takes 2,000 steps per mile, and the average woman takes about 2,437 steps per mile.

Therefore, walking 20000 steps a day works out to walking 10 miles (16 km) for the average man and 8.2 miles (13.2 km) for the average woman.

How Many Calories Do You Burn Walking 20000 Steps a Day?

One of the benefits of walking 20000 steps a day is that you will burn a lot of calories. 

Of course, the more you weigh, the faster you walk, the further you walk, and the steeper the incline, the more calories you’ll burn walking.

The best way to estimate the number of calories you burn walking 20000 steps a day is to monitor your heart rate and use a fitness watch that records the distance and speed that you are walking.

If you don’t have a heart rate monitor or GPS running watch, you can calculate the approximate number of calories you burn walking 20000 steps a day using the METs values for walking at different speeds and inclines.

Below, we’ve created a table that shows the calories burned walking 20000 steps at different paces and body weights based on the METs values for walking from the Compendium of Physical Activities. 

We used the average step length of 31 inches, so walking 20000 steps will total 10 miles.

5 Tips for Walking 20000 Steps a Day

Walking 20000 steps a day can seem completely overwhelming.

Here are some tips to help get you there:

#1: Consider a Weighted Vest

If you are walking 20000 steps a day, you have clearly developed excellent aerobic fitness, strong legs, strong lungs, and a strong heart.

To make your walking workouts more challenging, you can wear a weighted vest for part or all of the walk, gradually increasing the percentage of the time that you wear the vest.

#2: Train for an Event

Walking 20000 steps a day builds a fantastic fitness base, which can allow you to take part in lots of different physical activities without becoming completely exhausted.

One fun option is to train for an event.

For example, you might sign up to walk a 10k or half marathon, or you might want to go on a hiking trip or tour some exciting destinations like the Grand Canyon, Machu Picchu, or the Swiss Alps.

Setting a big, exciting goal can make it easier to stay motivated during your daily walks.

#3: Vary Your Walks

Add variety to your walking workouts to prevent boredom and fitness plateaus by continually challenging and changing the stimulus on your body.

Walk on different terrains, such as grass, trails, roads, or the treadmill, and vary the incline and speed that you walk. 

Consider adding intervals of brisk walking or steep hills to elevate your heart rate.

#4: Listen to Audiobooks or Podcasts

Walking 20000 steps a day can take quite a bit of time, but you can multitask during your walking workouts by enjoying a great audiobook or riveting or informative podcast.

You can also consider calling a friend and talking on the phone, brainstorming for an upcoming work meeting, or allowing your creative juices to flow so that you’re getting more than just your exercise done.

#5: Take Your Nutrition Seriously

The table above demonstrates that walking 20000 steps a day burns a lot of calories.

Therefore, it’s important to feed and hydrate your body like an athlete in training. 

Focus on eating unprocessed, natural foods like vegetables, fruits, lean proteins, whole grains, eggs, low-fat dairy, seeds, and nuts.

Drink plenty of water, and carry water on your walks, either via a handheld water bottle or a hydration pack.

There are so many benefits of walking 20000 steps a day, from improving the function and health of your body to improving your mental well-being and cognitive performance.

Although walking 20000 steps a day is definitely an investment of time, it is also an invaluable investment that will serve you well throughout your lifetime.
