How long does it take to hike a mile?
On an ordinary trail most hikers take 30 to 50 minutes a mile, and a mile that climbs 1,000 feet takes about an hour. Here's how to turn that into a finish time for your own hike, and plan a day that ends with daylight to spare.
Once you know how long a mile takes you, you can pick a trail that gets you to the top by lunchtime and back to the car with light left over. Without that number every hike is a guess, and the guess decides whether you get to hang around at the view or spend it checking your watch.
The short answer is that most people take 30 to 50 minutes to hike a mile of ordinary trail, and closer to an hour for a mile that climbs 1,000 feet. The longer answer is a number you can measure for yourself in an afternoon, and a couple of simple rules that turn it into a finish time for any hike you're looking at.
You need the miles, the climb and your breaks, plus a finish time worked backward from sunset. That's two minutes of arithmetic at the kitchen table the night before. Do it, and the last mile is an easy walk out instead of a hurried one under a headlamp.
How many minutes does a mile of trail take?
Somewhere between 20 minutes and an hour, depending on the ground, the climb and the hiker. The Washington Trails Association puts real hiking paces anywhere from half a mile an hour on a stroll to three on a fast hike. The rules below are the ones people plan with, and each assumes a different hiker.
| Rule of thumb | Flat trail | Add for climbing | What it assumes |
|---|---|---|---|
| Naismith's rule (1892) | 20 minutes a mile (3 mph) | 1 hour per 2,000 feet of ascent | Fit walkers, short halts only, on what Naismith called easy expeditions |
| AMC book time | 30 minutes a mile (2 mph) | 30 minutes per 1,000 feet of ascent | Walking time on White Mountains trail; add your breaks on top |
| Shenandoah National Park pace | 40 to 50 minutes a mile (1.5 to 1.2 mph) | Built in: the harder the hike, the slower the pace | An average hiker; the park says it ignores fitness, rest and exploring |
| AMC advice for beginners in the White Mountains | About an hour a mile (1 mph) | Built in | New hikers on the steep, rocky trails of New Hampshire's White Mountains |
Naismith from his own 1892 note in the Scottish Mountaineering Club Journal; book time as used in the Appalachian Mountain Club's White Mountain Guide, as described by The Big Outside; the pace bands from Shenandoah National Park's hiking difficulty page; the one-mile-an-hour figure from the AMC's beginner guide to the White Mountains.

Walking time; your breaks come on top.
1.2 miles an hour for the full distance.
"Some take longer," the park adds.
Why do the hiking time formulas disagree?
Hiking time formulas disagree because each one was written for a different hiker. Naismith's rule assumes a fit walker taking short halts, AMC book time a slower everyday hiker, and Shenandoah's paces fold the trail's difficulty into the speed itself. None of them counts real breaks, so on the same hike they can differ by several hours.
William Naismith was a Scottish mountaineer, and he set out his rule in 1892 in a short note about a spring day over three peaks: ten miles and 6,300 feet of climbing in six and a half hours, including short halts. Run that day through his formula and you get almost exactly six and a half hours, which was his point.
He was clear about who it was for, too: men in fair condition on easy expeditions. In other words, a fit, experienced walker who stops only briefly. Book time slows the flat pace to two miles an hour and charges more for the climbing, which lands closer to a normal day hiker.
Lunch, photos, a snack at every viewpoint, the kid who needs to retie a boot: none of it is in the formulas. That's why Half Dome comes out anywhere from seven hours to more than thirteen depending on which rule you pick, and why Yosemite's own figure of 10 to 12 hours sits between the book and the slowest band.
The rules also treat downhill as nearly free, and it isn't. Tobler's hiking function, a speed model the geographer Waldo Tobler published in 1993, has walkers moving fastest on a gentle downhill and slowing again as the grade steepens. On a steep, rocky descent you pick your footing with every step. Grand Canyon rangers tell hikers to expect the climb back out to take twice as long as the walk down, but the walk down isn't quick either.
How do you work out how long your hike will take?
Measure your own pace once, then use it with a climbing allowance. Hike for an hour on a normal trail with your usual pack and note the miles. Divide the hike's distance by that pace, add half an hour for every 1,000 feet of climb, add ten minutes of rest for every hour, and then pad the afternoon.
- 01
Measure your baseline pace
The Washington Trails Association has an easy method. Pack your usual daypack, start a GPS track and a timer at the trailhead, walk at whatever pace feels comfortable, and stop after an hour. The miles you covered are your miles per hour. Do it once on a fairly flat trail and once on one with some climbing, and you have your two numbers.
A GPS watch or a phone app does this for you. Just look at moving pace, not the average that includes your stops.
- 02
Get the distance and the climb
You need total miles and total elevation gain, not just the height of the summit. A trail that rolls over three hills can gain more than one that climbs straight to a higher top. Land managers' trail pages usually list both, and a map app will total the gain for a planned route.
- 03
Rate how hard it is
Shenandoah's formula is a quick sanity check. Multiply the elevation gain in feet by two, multiply that by the miles, and take the square root. Under 50 is easiest, 50 to 100 moderate, 100 to 150 moderately strenuous, 150 to 200 strenuous, and over 200 very strenuous. The park admits it's imperfect: steep short trails like Dark Hollow Falls score easier than they feel.
- 04
Turn it into moving time
Divide the miles by your flat pace, then add half an hour for every 1,000 feet of climbing, the way book time does. If you haven't measured your pace yet, use two miles an hour. For a 10-mile hike with 3,000 feet of gain, that's five hours plus an hour and a half: six and a half hours of walking.
- 05
Add your breaks
Both the Washington Trails Association and Grand Canyon's rangers suggest ten minutes of rest in every hour. On a six-and-a-half-hour walk that's another hour, before lunch. Groups, kids and photographers all add more, so be honest about which hiker you are.
- 06
Pad the afternoon, then set a turnaround time
Your pace drops as the day goes on, and WTA notes that your last few miles may be slower than your first. Add some slack for that, work out how long the way back will take from your turnaround point, and fix the latest time you'll turn around before you leave the car.
How do you set a turnaround time for a day hike?
Work backward from sunset. Decide when you want to be back at the car with light to spare, subtract how long the way down will take, and that's the latest you can be at the top. Here's the 10-mile, 3,000-foot example from above, on a day when the sun sets at 6:30 p.m.
Night before
Do the arithmetic
Six and a half hours of walking plus an hour of breaks makes about seven and a half hours on the trail. Check the sunset time for the date, and decide you want to be at the car an hour before it: 5:30 p.m. That leaves you a buffer for a slow mile or a wrong turn.
8:30 a.m.
Start
Seven and a half hours back from 5:30 p.m. is 10:00 a.m., so an 8:30 start builds in another hour and a half. Yosemite tells Half Dome hikers to leave around sunrise or earlier for the same reason. You can't make up time late in the day, but you can bank it in the morning.
9:30 a.m.
The one-hour check
Look at how far you've come. If you planned on two miles an hour and you've done a mile and a half, you already know the day will run long, and it's much easier to shorten it now than at 2 p.m. with the summit in sight.
About 1:15 p.m.
The top, if the plan holds
On an out-and-back with the climbing on the way in, the way up takes most of the time. Book time puts this hike at four hours of walking up and two and a half down. Add ten minutes an hour for breaks and that's about four and three-quarter hours up and three down.
Grand Canyon's rangers tell hikers to allow two thirds of their time for the climb and a third for the descent. They wrote that for the canyon, where the climb comes last, so treat it as a rough check here. It lands in about the same place.
2:30 p.m.
The hard turnaround
Subtract the three hours down from the 5:30 p.m. finish and the latest you can be on top is 2:30 p.m. If you're not there by then, you turn around wherever you are. The Appalachian Mountain Club suggests tying it to a landmark, too, so you turn around at 1 p.m. if you haven't reached halfway.
By 5:30 p.m.
Back at the car
If the plan held, you're down around 4:15. If you used the whole buffer and turned around at 2:30, you're back by 5:30, an hour before sunset, with headlamps still in the pack. Either way, you know more about your pace for next time.
What slows you down on a hike?
Mostly things the formulas can't see: a heavy pack, rough or snowy trail, the people you're with and how often you stop. The Washington Trails Association singles out heavy packs, snow cover and poor trail. Some things speed you up too.
Slows you down
- Rocks, roots and scrambling, which is why the AMC tells beginners in the White Mountains to expect about a mile an hour
- Snow, mud or ice underfoot
- A heavy pack, or water for a long dry day
- Steep descents, especially on loose or wet rock
- A group, which moves at the pace of its slowest member plus everyone's stops
- Heat, and the extra rest it demands
- The afternoon itself, since your last miles are often slower than your first
Speeds you up
- Smooth, graded trail with gentle switchbacks
- A light pack you've already worn for a few hikes
- A pace you could hold a conversation at, which Grand Canyon's rangers call the perfect speed
- Short, regular breaks instead of one long one
- Knowing the route, so you're not stopping at every junction
- Training for the climb and the descent, not just the distance
What do the hiking time terms mean?
- Naismith's rule
- An hour for every three miles on the map plus an hour for every 2,000 feet of climbing. Written by William Naismith in 1892, for fit walkers taking short halts.
- Book time
- The estimate used in the AMC's White Mountain Guide: 30 minutes a mile plus 30 minutes per 1,000 feet of climbing. Treat it as walking time and add your breaks.
- Elevation gain
- The total of every uphill stretch on a route, not just the difference between the trailhead and the top. It's the number that drives the climbing allowance.
- Moving time
- Time spent actually walking. A GPS watch separates it from elapsed time, which includes every stop.
- Turnaround time
- The latest clock time you'll keep heading out before you turn back, fixed before the hike and not renegotiated at the top.
- Tobler's hiking function
- A 1993 model of walking speed against slope. It has hikers moving fastest on a slight downhill and slowing on steeper grades in both directions.

Gear that helps you keep to the plan
A GPS watch tracks your moving pace so you don't have to. Poles make a long descent easier on your legs, and if the day runs long anyway, a headlamp means you can still see the trail.
Hiking time questions
How long does it take to hike 5 miles?
About two and a half to four hours on a moderate trail. At book time's two miles an hour, five flat miles is two and a half hours of walking. Add half an hour for every 1,000 feet of climbing and ten minutes of rest an hour. A beginner in the rocky White Mountains should plan on closer to five hours.
How long does it take to hike 10 miles?
Usually five to eight hours, and more on hard ground. Ten flat miles at two miles an hour is five hours of walking. A typical mountain day with 3,000 feet of climbing comes to about six and a half hours of moving time, and around seven and a half once you add breaks.
How long does it take to hike a mile uphill?
About an hour for a mile that climbs 1,000 feet, by book time: 30 minutes for the mile and 30 for the climb. Naismith's rule, written for fit walkers, gives about 50 minutes. A steep, rocky mile can take longer than either.
Is 2 miles an hour a good hiking pace?
Yes. It's the flat-trail pace built into the AMC's book time, and it's a sensible planning number for most adults. Shenandoah National Park gives average paces of 1.2 to 1.5 miles an hour, slower as its trails get harder, and the Washington Trails Association puts real paces anywhere from half a mile to three miles an hour.
How long does it take a beginner to hike a mile?
Plan on 30 to 60 minutes. On a smooth, gentle trail the planning paces run from Shenandoah's 1.5 miles an hour for its easiest hikes to book time's two, or 30 to 40 minutes a mile. On steep, rocky trail like New Hampshire's White Mountains, the Appalachian Mountain Club tells beginners to expect about a mile an hour.
Why does the hike down take so long?
Because steep descents aren't the free miles the formulas treat them as. Tobler's hiking function has walkers moving fastest on a gentle downhill and slowing again on steeper grades, and on loose or rocky ground you're choosing every step. You're also more tired by then, so the descent is often where a hike falls behind schedule.
