Mountaineering is measured in vertical gain. If your objective demands 1,200 m (3,900 ft) of climbing on summit day, your indoor training should be building toward that figure - and you cannot build toward a number you never see. Most treadmill consoles report belt distance, speed, and calories, but not total elevation gained. This treadmill elevation calculator fills that gap. To calculate treadmill incline elevation, enter your incline grade, your speed, and how long you walked: it returns your vertical gain in both metres and feet, along with the belt and horizontal distances behind it.
Trekking is measured in vertical gain, day after day. If your hardest day demands 1,350 m (4,429 ft) of ascent, as stage 2 of the Tour du Mont Blanc does, your indoor training should be building toward that figure, and you cannot build toward a number you never see. Most treadmill consoles report belt distance, speed, and calories, but not total elevation gained. This treadmill elevation calculator fills that gap. To calculate treadmill incline elevation, enter your incline grade, your speed, and how long you walked: it returns your vertical gain in both metres and feet, along with the belt and horizontal distances behind it.
How the calculation works
The maths is straightforward trigonometry. Your belt distance is simply speed multiplied by time - how far the belt carried you. The incline grade is the slope, expressed as a percentage, where grade equals rise divided by run, multiplied by 100. A 12 percent grade means 12 units up for every 100 units along the ground.
To get vertical gain, the grade is converted to a slope angle - the inverse tangent of the grade divided by 100 - and the belt distance is multiplied by the sine of that angle. That separates the climbing component from the horizontal component. It is worth noting that the simple shortcut of "distance times grade percent" slightly overstates the climb, because belt distance runs along the slope rather than across the ground. At the grades used for mountain training the difference is small, but this calculator uses the precise formula so the figure you track is accurate.

Using it for mountain training
Using it for trek training
Vertical gain is the currency of mountaineering, so it is the number to train against. Look up the climbing your objective demands - a peak page in the Train for a Peak hub gives you the summit-day vertical - and use this calculator to see how a given incline and duration stack up against it. Most mountain training on a treadmill sits at a 10 to 15 percent grade walked at a steady, conversational pace, so the effort stays aerobic.
Vertical gain is the currency of trekking, so it is the number to train against. Look up the ascent your trek demands (each trek page gives the stage profile and its hardest day: Kilimanjaro 1,222 m, the Tour du Mont Blanc 1,350 m, the Annapurna Circuit 966 m) and use this calculator to see how a given incline and duration stack up against it. Most trek training on a treadmill sits at a 10 to 15 percent grade walked at a steady, conversational pace, so the effort stays aerobic.
A treadmill is one good way to build the uphill engine indoors, but it is not the only one, and it has real limits - it never trains the descent. For how it compares with the stepping machine, read StairMaster vs incline treadmill for mountaineering, and for where machine work fits in a complete plan, see the best exercises for mountaineering guide.
A treadmill is one good way to build the uphill engine indoors, but it is not the only one, and it has real limits: it never trains the descent, and a trek's descents are long (the Inca Trail drops 1,370 m on day 3, Kilimanjaro 2,827 m on the summit night). For the descent, read eccentric training for the descent; for the stepping machine, the StairMaster calculator does the same job as this page.
Machine sessions are one piece of a build.

How to calculate treadmill incline into real vertical gain
Treadmill incline is a percentage: a 10 percent grade means 10 units of rise for every 100 units of belt distance. To calculate treadmill incline into real vertical gain, take your belt distance (speed multiplied by time) and multiply it by the sine of the slope angle, where the slope angle is the inverse tangent of grade divided by 100. The rough shortcut - belt distance times grade - slightly overstates the climb, because the belt runs along the slope, not across the ground. Above returns the exact figure in metres and feet.

Treadmill elevation calculator: what the output means
The treadmill elevation calculator returns two numbers: vertical gain (how many metres or feet you climbed) and, optionally, its ratio against your goal peak's summit-day vertical. A one-hour walk at 5 km/h and 12 percent grade gives about 600 m (1,970 ft) of vertical elevation, which is a strong single-session block. For an objective demanding 1,500 m (4,900 ft) summit-day, you would need two-to-three sessions like that per week during the build phase, layered with real-terrain days when available.

Common questions
Is this a treadmill vertical calculator or treadmill vert calculator?
Yes. A treadmill vertical calculator, treadmill vert calculator, and treadmill elevation calculator all describe the same job: turning incline, speed, and time into the amount of climbing you actually did. That is what this tool does. Enter your incline grade, your speed, and your duration, and it returns your vertical gain in both metres and feet, along with the belt distance and horizontal distance behind it, plus your rate of climb in vertical metres per hour.

How is treadmill vertical gain calculated?
Vertical gain is the climbing component of the distance you cover. The treadmill belt distance equals your speed multiplied by your time. The incline grade is the slope, where grade percent equals rise divided by run times 100. The vertical gain is the belt distance multiplied by the sine of the slope angle, where the slope angle is the inverse tangent of the grade divided by 100. This calculator does that maths for you and reports the result in both metres and feet.

Does treadmill incline equal real elevation gain?
The vertical maths is the same: a given grade walked for a given belt distance produces a defined amount of climbing whether indoors or out. What a treadmill cannot reproduce is uneven ground, the descent, altitude, and a real pack moving over rock and snow. Treat the calculated vertical gain as an accurate measure of the uphill training stimulus, not as a full simulation of a day in the mountains.

What incline is good for mountaineering training?
Most mountain training on a treadmill sits between 10 and 15 percent grade, walked at a steady, conversational pace so the effort stays aerobic. That range produces a useful rate of vertical gain without tipping the session too hard. Steeper grades suit shorter, harder efforts. Use this calculator to see how much climbing a given grade and duration actually delivers, then build toward the vertical demand of your objective.
What incline is good for trek training?
Most trek training on a treadmill sits between 10 and 15 percent grade, walked at a steady, conversational pace so the effort stays aerobic. That range produces a useful rate of vertical gain without tipping the session too hard. Steeper grades suit shorter, harder efforts. Use this calculator to see how much ascent a given grade and duration actually delivers, then build toward the ascent of your trek's hardest day.
Is treadmill belt distance the same as horizontal distance?
Not exactly. The belt distance is measured along the inclined surface, so it is slightly longer than the horizontal distance covered. At the grades used for mountain training the difference is small, but it matters for an accurate vertical figure. This calculator separates the two, reporting belt distance, horizontal distance, and vertical gain so you can see exactly what your session produced.
