Work out swimming split time instantly with clear inputs, formula shown and shareable results.
Even-pace splits divide the target time by the number of split lengths in the race, and the per-100 figure normalises pace across race distances. Swimmers race by feel against a pace clock, so having the target split written down in seconds is what makes negative or even splitting executable.
Split time
split = total time / (race distance / split length)
Pace per 100 m
pace = total time x 100 / race distance
split = total time / (race distance / split length). Even-pace splits divide the target time by the number of split lengths in the race, and the per-100 figure normalises pace across race distances.

Enter target total time, race distance, split length. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
