Trail pace & climbing speed calculator
On the trail, raw pace lies — 6:30/km up a climb is a huge effort, the same number on the flat is a jog. This calculator gives you a grade-adjusted pace (your effort translated to a flat-road equivalent) and your climbing speed, the metres of elevation you gain per hour.
Grade-adjusted pace
4:49 /km
Flat-effort distance: 28.0 km
Climbing speed
356 m/h
Vertical metres per hour (VAM)
Grade-adjusted pace uses the coaching heuristic 100 m climb ≈ 1 km of flat effort. Climbing speed = elevation gain ÷ time. Both are planning estimates; technical terrain and descents shift real numbers.
Train by effort, not by pace.
Coach Leo plans and adjusts your trail sessions by real effort — climbs, descents and fatigue included — instead of a flat pace that means nothing in the mountains.

Frequently asked questions
What is grade-adjusted pace (GAP)?
Grade-adjusted pace converts your effort on a hilly route into the pace you'd be running for the same effort on the flat. It lets you compare a hilly run to a flat one and pace climbs sensibly. We estimate it by adding roughly 1 km of flat distance for every 100 m of climbing.
What is climbing speed (VAM) and what's a good value?
Climbing speed, often called VAM, is how many vertical metres you climb per hour. Recreational trail runners climb roughly 500–800 m/h on runnable grades; strong mountain runners push past 1,000–1,500 m/h. It's the cleanest way to compare climbing performances across different routes.
Why is pace useless on the trail?
Because the same effort produces wildly different paces depending on the grade. Your pace collapses uphill and skyrockets downhill even at a constant effort. That's why trail runners pace by heart rate, perceived effort or power, and often power-hike steep climbs, which is faster for the same energy.
How do I use these numbers to train?
Track your grade-adjusted pace to compare hilly sessions week to week, and your climbing speed to see your fitness improve. Set climb targets in m/h rather than pace, and budget your race effort by vertical gain, not just distance.
How accurate is the 100 m ≈ 1 km rule?
It's a robust planning heuristic, not physics. Real cost depends on grade steepness, surface, altitude and your hill fitness; very steep or technical climbs cost more. Use it to size sessions and compare efforts, and let your heart rate confirm the real load on the day.
Does Coach Leo coach for trail and elevation?
Yes. Leo plans by effort and accounts for elevation, so trail sessions are sized by real load rather than a flat pace. It reads your climbs and descents from Strava and adapts the week to how you're recovering.
