Accurately calculate vertical gain and plan treadmill workouts for hiking and mountain prep.
Training for mountain sports requires more than just logging miles. Logging vertical elevation gain builds legs, lungs, and active longevity. Running or walking on an incline treadmill is one of the most effective and controllable ways to simulate mountain ascents.
However, basic treadmills often display inaccurate stats or omit essential metrics like vertical ascension rate. This calculator provides precision metrics for vertical training.
On an incline, the treadmill belt distance is the hypotenuse of the triangle. Most basic vertical calculators simply multiply distance by grade (e.g. Distance × 0.20 for a 20% incline).
To ensure mathematical accuracy at higher angles, our calculator uses the trigonometric sine of the angle of inclination:
Elevation = Distance × sin(arctan(Incline %))
This ensures your training log is scientifically accurate, whether you walk at a mild 5% or crawl up a steep 30% slope.
Analyze your completed incline session metrics.
VAM (Velocità Ascensionale Media) measures your vertical climbing speed in vertical meters per hour—a key metric for cyclists, trail runners, and mountaineers.
Find the distance required on the treadmill display to hit your climb target.
To climb your desired vertical feet at this grade, run/walk until your treadmill display shows this mileage.
