Calculate pace per mile or kilometer and project finish times for target distances.
Overview
A pace calculator converts between distance, elapsed time, and pace. Runners use it to set race strategy and interval targets.
Pace precision helps prevent starting too fast, supports negative splits, and improves consistency on long efforts.
Steps
Solve for pace, time, or distance.
Use miles or kilometers consistently.
Provide any two of time, distance, and pace.
The missing variable is solved directly.
Translate pace into split times per lap or km.
Set interval pace bands with recovery timing.
Math
Pace = Time / Distance; Time = Pace x Distance; Distance = Time / Pace
Pace is simply unit time per unit distance, making conversions between race distance and finish time straightforward.
Worked cases
Pace = 52.5 / 10 = 5.25 min/km
Pace = 5:15 per km
Time = 8 x 13.1 = 104.8 min
Finish time about 1:44:48
Distance = 45 / 6 = 7.5 km
Distance covered: 7.5 km
