What this result means
Treadmill interval programs are usually set as speed and time, not track distance. This page converts work belt speed and work seconds into distance, then builds the same session clock as the track interval workout tool.
Use it when the deck shows km/h or mph and a countdown. Use the interval workout calculator when you think in metres and pace on a track or road.
10 × 60 s at 16.0 km/h with 60 s rest: each work bout is about 0.267 km; total work about 2.67 km; session about 19:00 including rest between reps.
8 × 90 s at 14.0 km/h with 75 s rest scales the same way: work distance from speed × time, then work × reps plus rest × (reps − 1).
Calculation method
Work distance (km) = km/h × (work seconds ÷ 3600). Session time = work × reps + rest × (reps − 1). Same session structure as the track interval engine.
Exact arithmetic on the numbers you type. Rest is recovery time, not a physiology model.
Warm-up and cool-down are not included unless you add them yourself. Belt acceleration between speeds is ignored.
Frequently asked questions
How do I enter a 1-minute hard / 1-minute easy set?
Put the hard belt speed as work speed, 60 seconds as work duration, 60 seconds as rest, and the rep count you want.
Is this the same as the interval workout calculator?
Same session clock idea. That tool takes work distance and pace. This one takes work speed and duration.
Does incline affect the session?
Not in the clock. Incline changes effort; use the incline calculator for flat-equivalent pace.
Are rest seconds after the last rep counted?
No. Rest is multiplied by reps minus one, the usual between-rep recovery.
