How it works

At an even pace, split time equals total time multiplied by split distance ÷ total distance. A 1,500 m run on a 400 m track is three full laps and 300 m. At 5:00 total, the full laps take 1:20 each and the final 300 m takes 1:00.

Use the measured lap length for the lane or route you are running. The calculator does not adjust for lane stagger.
