Pace per 100 is the swimmer's unit
Swimmers do not talk about minutes per mile. Every set, every race and every workout is written per 100 metres or per 100 yards, because that is the distance short enough to correct within a length and long enough to be meaningful. Thirty minutes for 1500 m is 2:00 per 100 m, which is a solid recreational pace. Most swimming pace tools hand you that one number and stop; the split table and the projections below are what make it useful for planning a set.
Pool and open water are different
A pool time includes a push off every 25 or 50 m, plus clear water and a straight line. Open water removes the walls, adds sighting and puts other swimmers in your path. Expect 3–8 seconds per 100 m slower in a lake or sea, more in chop. The projections here assume pool conditions.
Using the projections
The table extends your pace to 500 m, 750 m, 1000 m, 1500 m, 1900 m and 3800 m. Those are the distances that matter for pool events and triathlon. The extension is arithmetic — holding 2:00 per 100 m for 3800 m is a different challenge from holding it for 1500 m, and most swimmers fade 3–5% over the longer distance.
Frequently Asked Questions
What is a good pace per 100 m?
Recreational swimmers sit around 2:00–2:30; club swimmers 1:30–1:50; competitive age-groupers under 1:25. The right target depends on your stroke and training volume.
Why is my pace per 100 yd different?
A yard is 0.9144 m, so 100 yd is 91.44 m. The same speed produces a faster per-100-yard number — about 8.6% faster.
Should I include rest in the time?
No. Enter swim time only; rest intervals make the pace meaningless.
