How Many Steps Is a Marathon?
About 56,000 steps for many adults, usually 53,000–63,000. Runners take fewer, longer steps.
Walking a marathon is about 56,000 steps for many adults. Step length moves that count, and the usual walking band is about 53,000–63,000. A half marathon is about 28,000. Running the same road takes fewer, longer steps, roughly 36,000–43,000.
Treat the range as a sketch. Then check it on a walk you take.
The distance
World Athletics sets the marathon at 26 miles 385 yards, standardised in 1921. That is 42.195 km, or 42,195 metres. A mile is 1,760 yards, and 385 ÷ 1,760 = 0.21875, so 26 miles 385 yards is 26.21875 miles, written as 26.2 miles.
Half that distance is 42,195 ÷ 2 = 21,097.5 metres, which is 21.0975 km. 26.2 ÷ 2 = 13.1 miles.
A step-length chart for the full and the half
Divide the metres by the length of one step. These rows use the same example lengths as the 10 km and 5 miles charts. They are examples, not a reading of your walk.
- About 0.67 m: 42,195 ÷ 0.67 = 62,978, roughly 63,000 steps. The half is 21,097.5 ÷ 0.67 = 31,489, roughly 31,500 steps.
- About 0.75 m: 42,195 ÷ 0.75 = 56,260, roughly 56,000 steps. The half is 21,097.5 ÷ 0.75 = 28,130, roughly 28,000 steps.
- About 0.80 m: 42,195 ÷ 0.80 = 52,744, roughly 53,000 steps. The half is 21,097.5 ÷ 0.80 = 26,372, roughly 26,400 steps.
The University of Nebraska Medical Center’s walking guide puts an average stride at about 2.5 feet and says a mile takes just over 2,000 steps. How many steps are in 1 mile works that 2.5 foot stride out as 5,280 ÷ 2.5 = 2,112 steps a mile. Across 26.2 miles, 26.2 × 2,112 = 55,334, about 55,000 steps, close to the 0.75 m row.
Running steps from one race
Cordingley, Leiter, and McRae filmed runners during a marathon and reported the step lengths in Medicine & Science in Sports & Exercise (2020). At km 11 the average was about 1.16 m for the men and 1.05 m for the women. Near km 39 the steps were shorter, about 1.05 m for the men and 0.98 m for the women. These were runners filmed in one race.
The same 42,195 metres, divided by those lengths:
- 42,195 ÷ 1.16 = 36,375, about 36,400 steps
- 42,195 ÷ 1.05 = 40,186, about 40,200 steps
- 42,195 ÷ 0.98 = 43,056, about 43,100 steps
Dividing the whole course by a length measured at one marker is an estimate, and tired legs late in the race take shorter steps. For runners like those, the course lands around 36,000–43,000 steps, roughly 13,000–20,000 fewer than the 0.75 m walking row.
How long the walk takes
Pace sets the clock. The NHS describes a brisk walk as about 3 miles an hour, faster than a stroll, and you can still talk. At that pace, 26.2 ÷ 3 comes to 8 hours 44 minutes of brisk walking. A half marathon at the same pace is 13.1 ÷ 3, which is 4 hours 22 minutes.
Stops add clock time, and they add no steps.
A marathon spread over ordinary days
Seven days at 8,000 steps is 7 × 8,000 = 56,000, the round figure on the 0.75 m row. Ten days at 10,000 steps is 10 × 10,000 = 100,000. 100,000 ÷ 56,260 = 1.78, about 1.8 times that walking marathon, almost two. How many miles is 10,000 steps and how long 10,000 steps takes cover one of those days on its own.
Six people, one day's steps
Six people sharing a marathon's worth of steps is 56,260 ÷ 6 = 9,377, about 9,400 steps each. Eight people is 56,260 ÷ 8 = 7,032.5, about 7,000 steps each. A hive is a small group of friends who can share a day's steps.
Find your own marathon
Walk a mile you already know, a track lap or a route measured on a map. Note the counter at the start and at the end, subtract, and multiply by 26.2. For a half, multiply by 13.1. That product is your course. Your own number beats the chart.
On a steep or rocky trail, shorter steps raise the count for the same distance. A hike still counts, and a hilly course can take more steps than the pavement rows above.
Walk a share with a few friends this weekend. Start a walking streak with friends if you want the same people out again tomorrow.
