Swim pace & split calculator
Enter your race distance and goal time. Get the even split you need to hold — per 25, 50, or 100 — and a full split table to pace off.
Key takeaways
- Even splitting means holding the same pace each length — the most efficient way to hit a goal time.
- Enter distance + goal time; get the split you must hold and a cumulative table.
- Per-100 pace lets you compare efforts across different race distances.
- Write your target splits on your arm so you can check them on the wall.
| At | Split | Cumulative |
|---|---|---|
| 50 | 32.50 | 32.50 |
| 100 | 32.50 | 1:05.00 |
About this tool
Most personal bests come from even or slightly negative splitting, not from going out too fast and dying. This calculator shows the exact pace to hold so a goal time is a plan, not a guess.

- 2
Pick a split length
Choose 25, 50, or 100 depending on how you count the pool.

Hold the per-split pace; the cumulative column is your check at each wall.
Frequently asked
What is a good way to split a race?
Even or slightly negative splitting — holding a steady pace and finishing at least as fast as you started — is the most reliable way to hit a goal time without fading.
Does this work for yards and meters?
Yes. The math is the same; just enter the distance in whatever unit your pool uses.
How do I remember my splits during the race?
Write your target splits somewhere waterproof you can glance at — an EHLStat tattoo is built to hold race info in clear ink through the whole session.
Carry your splits to the blocks
Write your goal splits on an EHLStat tattoo and check them on every wall.
