Distance + elevation → hiking time by DAV/SAC formula
This calculator estimates your hiking time based on distance and elevation gain, using the widely trusted DAV/SAC formula (4 km/h on flat terrain, 300 m/h of ascent). It takes the guesswork out of trail planning so you know exactly how long a hike will take. Just enter the distance and elevation – and you'll have a reliable time estimate in seconds.
Hiking time is estimated by dividing the horizontal distance by your walking speed and adding extra time for ascent and descent, then combining the two figures. Most methods add the smaller of the horizontal and vertical time components as a fraction, and you should add breaks separately.
That pace is solid for hiking, since it sits at the upper end of typical walking speeds on trails. On steep or rocky terrain with a loaded pack, the same distance will take noticeably longer, and that is normal.
Most day hikes take a few hours, because typical routes are short enough to finish in a morning or afternoon. The actual time depends far more on elevation gain, terrain and break length than on distance alone.
On flat, easy trail a hike of that length covers roughly a mile at a normal walking pace. With steady uphill it can be less than half of that, since climbing eats time quickly.
Hiking can help reduce belly fat, but only as part of an overall calorie deficit, since fat loss is not targeted to specific body areas. Long, moderate hikes burn a lot of energy and are easy on the joints, which makes them sustainable.
A hike of that distance is moderate for someone with regular walking fitness and hard if you are untrained or the route has heavy elevation gain. Pack weight, heat and technical footing raise the difficulty more than the mileage itself.
Gummy bears are cheap, light, and made almost entirely of fast-absorbing sugar, so they deliver quick energy on the trail. They also do not melt or crumble in a pack the way chocolate or bars do.
Walking that much daily typically improves cardiovascular fitness, endurance and leg strength, and can lead to weight loss if you do not eat back the extra calories. Watch for overuse issues in the feet, shins and knees, especially if you ramp up suddenly.
Yes, a beginner can manage that distance on a well-marked trail with moderate elevation gain. Start with a slow pace, take regular breaks, and bring water and broken-in shoes.
Planning a hike and wondering how long it will take? The Hiking Time Calculator on this page uses the scientifically established DAV/SAC formula (from the German Alpine Club and Swiss Alpine Club) to give you a reliable, realistic estimate of your hiking duration. Simply enter your route distance and elevation gain/loss, and get an accurate hiking time in seconds.
The DAV/SAC formula is the gold standard for estimating hiking time in the Alpine world. It was developed to account for both the horizontal distance covered on a trail and the physical effort required to climb or descend elevation. The formula assumes an average, moderately fit hiker carrying a day pack.
The core assumptions are:
The total hiking time is calculated by taking the larger of the horizontal time and the vertical time, then adding half of the smaller value. This elegant method consistently outperforms simple distance-based estimates, especially on mountainous terrain.
Using this free tool is straightforward. Just input three values:
The calculator instantly returns your estimated hiking time in hours and minutes. Note that this is net walking time – it does not include rest breaks, meals, or photo stops. Most hikers should add 10–15 minutes of breaks per hour of calculated hiking time.
You're planning a hike in the Peak District: 10 km with 350 meters of ascent and 350 meters of descent. The calculator estimates approximately 3 hours 20 minutes of walking time. Add a 30-minute lunch break and you're looking at a comfortable 4-hour outing – perfect for a full morning adventure.
A classic Alpine hike: 9 km, 1,100 meters of ascent, 400 meters of descent. Elevation dominates here: ascent time alone is 3 hours 40 minutes. Total estimated hiking time: approximately 4 hours 50 minutes. With an early 6 AM start, you can summit and descend safely before afternoon thunderstorms arrive.
A gentle walk through a national park: 6 km, 120 meters up, 120 meters down. Result: approximately 1 hour 45 minutes – a relaxing half-day activity suitable for families with children or beginners.
Underestimating how long a hike takes is one of the leading causes of mountain emergencies worldwide. Hikers caught in the dark, in deteriorating weather, or without enough water and food face serious risks. A reliable hiking time estimator helps you:
The DAV/SAC formula gives excellent baseline estimates, but real-world conditions vary. Keep these factors in mind:
The formula works best for standard hiking and mountain walking. For technical climbing, via ferrata routes, or glacier travel, additional factors like rope time and belaying should be considered separately. For trail running, the estimates will be too slow.
No – the result is pure walking time. A good rule of thumb is to add 10–15 minutes of rest for every hour of calculated hiking time, plus any planned stops at viewpoints, summits, or huts.
For an average fit adult hiker, the formula is accurate to within about ±15%. It's widely used by professional mountain guides and appears on trail signs throughout the Alps, making it the most trusted standard available.
Absolutely. Break your multi-day route into individual daily stages, calculate each one separately, and you'll have a reliable itinerary. Don't forget to account for cumulative fatigue on days 3 and beyond.
Add up all elevation gains to get total ascent, and all elevation losses to get total descent. Enter these totals along with the full distance. The formula handles combined terrain well.
