The average time it takes to walk a mile is about 20 minutes at an easy pace. If you’re an American, you probably think in miles when it comes to walking distances, since the United States is one of the only countries that still use miles instead of kilometers.

But most walking routes and runs are described in kilometers. Use these charts to calculate your time and distance in miles and kilometers and find out how long it takes to walk one mile, three miles, five miles, and so on.

Conversion Tools

To convert your walking distance in miles to kilometers, you can do some simple math using these equations:

You can also look up your distance on the charts below, ranging from a quarter-mile to the marathon distance of 26.2. Or you can use this pace calculator.

How Long It Takes to Walk a Mile

There are plenty of apps and gadgets that can help you to determine your pace and distance. You can also use these charts to figure out how long it might take you to walk different distances based on your pace category.

How Long It Takes to Walk 3 Miles or Less

Walking 3.1 miles is equivalent to a 5 kilometer distance. Below, you can see how long it may take you to walk 3.1 miles or less. You can see how long it might take depending on your speed, categorized by fast, moderate, or easy pace.

How Long It Takes to Walk 3 to 6 Miles

The 3.1-mile distance equals the 5K distance of many walks you may participate in for charity or for fun. You can walk it in an hour or less.

The 6.2-mile distance (10K) is a good distance to try if you’re thinking about doing a half or full marathon one day. It takes about 2 hours or less.​

This chart begins at a distance just slightly longer than a 5K and provides data for up to a 10K distance.

How Long It Takes to Walk 6.5 to 13 Miles

The half marathon distance of 13.1 miles is just over 21 kilometers. If you plan to participate in a half-marathon event, you will want to choose a walker-friendly race, or you’ll arrive at the finish line hours after the runners have eaten all of the finish line goodies and gone home.​

This chart begins at a slightly longer distance than 10K and provides data for up to a half marathon distance.

How Long It Takes to Walk a Half or Full Marathon

The remaining chart takes us up to the marathon distance of 26.2 miles or 42.2 kilometers. Walking a marathon will take nearly 5 hours, even at a fast pace without rest stops.

This chart begins at a distance just slightly longer than a half marathon and provides data for up to a full marathon.

Factors Affecting Walking Time

Several factors can affect your walking time. First, if you are walking solely for enjoyment and light exercise, you may not push yourself to walk faster. So, purpose and intent affect walking time.

You will typically walk faster than usual when participating in an event or competition. An easy pace will mean you may fall to the back of the group, while at a fast pace, you may be up with some of the run/walkers or other face-paced walkers.

Aside from intent, physical factors including height, weight, fitness level, and body composition, and environmental factors such as incline (hills), weather, and ground surface (smooth or rough) can all affect walking time.

A Word From Verywell

Whether you want to walk for a specific distance or time, knowing how far and how long you may walk can help you plan your exercise. Using these charts can help you know if you are progressing or if you are walking at the pace you wish to. You can use these charts to train for specific walking events, such as a 5K, 10K, half, or full marathon.

Definition: A mile (symbol: mi or m) is a unit of length in the imperial and US customary systems of measurement. It is currently defined as 5,280 feet, 1,760 yards, or exactly 1,609.344 meters.

History/origin: The mile is an English unit (predecessor of Imperial units and United States Customary Units) of length. The use of the abbreviation «m» for mile was common before the widespread adoption of the metric system; after the adoption of the metric system, «mi» became the preferred abbreviation in order to avoid confusion between miles and meters. The definition of a mile as 5,280 feet (or 8 furlongs), sometimes referred to as the statute mile, international mile, or land mile, which differs from the Roman mile of 5,000 feet, developed due to the importance of the furlong in England, back in 1593. There also exist a number of units based on, or closely related to, the Roman mile, including the nautical mile (1.852 km exactly), Italian mile (

1.852 km), and the Chinese mile (500m exactly).

Current use: Although most countries have adopted the metric system and use kilometers, rather than miles, to express land distance, the mile is still prevalently used in countries such as the United States (US), United Kingdom (UK), Myanmar, and Liberia, as well as some other countries which are either US or UK territories, or have historical ties with either country.

Kilometer

Definition: A kilometer (symbol: km) is a unit of length in the International System of Units (SI). One kilometer is equivalent to 0.6214 miles.

History/origin: The prefix kilo- is a metric prefix indicating one thousand. One kilometer is therefore one thousand meters. The origin of the kilometer is linked to that of the meter, and its current definition as the distance traveled by light in 1/299 792 458 second. This definition is subject to change, but the relationship between the meter and the kilometer will remain constant.

Current use: It is currently the official unit of measurement for expressing distances between geographical places on land in most of the world. However, there still remain a number of countries that primarily use the mile instead of the kilometer including the United States and the United Kingdom (UK). Unlike the United States, the UK has adopted the metric system; while the metric system is widely used in government, commerce, and industry, remnants of the imperial system can still be seen in the UK’s use of miles in its road systems.

›› Definition: Mile

A mile is any of several units of distance, or, in physics terminology, of length. Today, one mile is mainly equal to about 1609 m on land and 1852 m at sea and in the air, but see below for the details. The abbreviation for mile is ‘mi’. There are more specific definitions of ‘mile’ such as the metric mile, statute mile, nautical mile, and survey mile. On this site, we assume that if you only specify ‘mile’ you want the statute mile.

›› Definition: Kilometer

A kilometre (American spelling: kilometer, symbol: km) is a unit of length equal to 1000 metres (from the Greek words khilia = thousand and metro = count/measure). It is approximately equal to 0.621 miles, 1094 yards or 3281 feet.
