Formula

pace/100m = (time ÷ distance) × 100

Pool swimming pace is usually quoted as mm:ss per 100 metres.

Worked example

400 m in 6:30 is 1:37.5 per 100 m.

Where this can give the wrong answer

  • Open water adds navigation and current.
  • Turns and push-offs affect pool splits.
  • Wetsuit buoyancy speeds open water.

FAQ

Use 400 m and 200 m times separately for critical swim speed — this is single-effort pace.
