Lap Split Calculator
Set your race goal
Use one common goal clock, for example 20:00 or 2:10.5.
Changing a unit converts the displayed value and keeps the same physical distance. Mile presets use the existing approximate 1609.34m factor.

Even pace: time at a checkpoint = goal time × checkpoint distance ÷ race distance. Clocks are rounded to a tenth; very short positive segments show <0.1s. Display labels are rounded; calculations retain unrounded values.
Set an even-pace checkpoint plan and retain the full finish.
