Trail Fitness Calculator
A quick estimate of what your planned multi-day hike will actually ask of your body.
"15 km a day" sounds manageable until you add ten days, alpine terrain and a loaded pack. This calculator turns your plan into the numbers that matter: total distance, total climb and descent, and the peak load going through your knees.
It is different from the Trail Readiness self-checks, which ask what kind of trail suits you right now. This one answers a narrower question: can I handle this specific route as I have planned it?
The climb nobody mentions
Total elevation gain across the whole trip, translated into flights of stairs so the number means something.
Descent counts too
Going down is what wrecks knees. You get the descent load, not just the uphill hero numbers.
Your pack, your load
Light, standard or heavy pack changes the peak load through your joints on every step.
Nothing stored
Enter numbers, read the result, close the tab. Nothing about your trip leaves your browser.
