Built for clearer swim planning
SwimTimeCalculator.com is an independent set of browser-based tools for comparing courses, calculating time, reviewing pace, and planning race splits.
Why this site exists
Swimmers often move between 25-yard, 25-meter, and 50-meter pools. The results are easy to compare badly. We built a fast tool that presents the estimate and its assumptions together.
Our principles
- Useful before complicated.
- Transparent estimates instead of false precision.
- Core tools available without an account.
- Fast pages that work well on a phone at the pool.
