Calculate swimming pace per 100m or 100yd from split times and distance. Convert between pace formats for pool and open water training plans.
Calculate critical swim speed (CSS) threshold pace from 400m and 200m time trial results. Set aerobic training zones for swimmers and triathletes.
Calculate even swimming split times for race pacing and interval training. Generate negative, even, or positive split targets for any distance.
This tool applies a standard formula from the relevant domain. The computation is deterministic — given the same inputs, the result is always identical. The formula accounts for the primary variables that determine the output.
Weekly volume = Σ (Distance × Sessions); Periodization: Base 80% / Build 100% / Peak 60%The calculation requires: Distance per Session, Sessions per Week, Unit, Plan Duration. Each parameter contributes to the final result according to the formula above. Accuracy depends on the precision of your input measurements.

Check the expected unit for each input field (shown as suffix). Converting between imperial and metric units before entering values prevents calculation errors.
Ensure denominator values (divisors) are non-zero. The calculator validates this, but understanding which fields cannot be zero helps interpret results correctly.
Calculate weekly swim training volume in yards or meters. Free online swimming calculator with instant, accurate results. It applies the calculation formula (Weekly volume = Σ (Distance × Sessions); Periodization: Base 80% / Build 100% / Peak 60%).
