Mile Pace Calculator

Gait speed reports metres per second over a short measured walkway.
Course distance in kilometres.
Alternative to kilometres. Ignored when a kilometre distance is given.
Elapsed time in seconds.
Alternative to seconds, e.g. 3:30:00 or 25:00.
Seconds per kilometre. Needed when solving for time or distance.
Alternative to seconds per kilometre, e.g. 5:00.
Distance between rows of the split table. 0 suppresses the table.

Worked out from OpenStax Elementary Algebra 2e, proportional relationships (rate = quantity per unit) and 2 other sources.
The course has more splits than the display limit of 1; raise "Maximum splits shown" to see the rest.

How this is worked out

6 steps
  1. Distance = 5 km (3.1069 miles).
  2. Elapsed time = 1500 s (25:00).
  3. Pace = time / distance = 1500 / 5 = 300 s per km.
  4. Pace per mile = 300 x 1.609344 = 482.803 s.
  5. Speed = distance / hours = 5 / (1500 / 3600) = 12 km/h.
  6. Split table built at 1.609344 km intervals.
