Treadmill Pace & Incline Calculator
What a treadmill speed+incline equals outdoors — the 1% rule and the energy-equivalent pace, computed.
Jones & Doust measured it in 1996: at training paces, 1% incline compensates for the missing air resistance — the famous rule is real but speed-dependent (matters above ~12 km/h, negligible jogging). Above that baseline, grade is honest extra work; 10 km/h at 5% runs like ~11.2 flat.

About Treadmill Pace & Incline Calculator
Jones & Doust measured it in 1996: at training paces, 1% incline compensates for the missing air resistance — the famous rule is real but speed-dependent (matters above ~12 km/h, negligible jogging). It applies 1% incline ≈ outdoor flat (air-resistance offset); each extra 1% ≈ ~3% harder. Use the Treadmill Pace & Incline Calculator to get an instant, clearly-explained result with the working shown step by step — free, private and with the source method cited.

Frequently asked questions
How does the Treadmill Pace & Incline Calculator work?+
Jones & Doust measured it in 1996: at training paces, 1% incline compensates for the missing air resistance — the famous rule is real but speed-dependent (matters above ~12 km/h, negligible jogging). The calculation uses the formula: 1% incline ≈ outdoor flat (air-resistance offset); each extra 1% ≈ ~3% harder. Everything runs instantly in your browser as you type — your inputs are never uploaded.
Is the Treadmill Pace & Incline Calculator accurate, and what is it based on?+
The method is traceable to authoritative sources, including Jones AM & Doust JH, J Sports Sci 1996 — 1% treadmill grade; Minetti AE et al., J Appl Physiol 2002 — energy cost of gradient running. Results are estimates — individual variation always applies, so treat the output as a well-grounded starting point.
Is the Treadmill Pace & Incline Calculator free and private?+
Yes. It's completely free with no sign-up, and all computation happens locally in your browser, so none of your health data ever leaves your device.
Can I use this for medical decisions?+
This tool is for general fitness information only, not medical or training advice. Consult a professional before changing your routine.
What can I use the Treadmill Pace & Incline Calculator for?+
