How to use it

  1. Open Swim Pace Calculator and enter your current baseline accurately.
  2. Adjust one variable at a time so changes are easy to interpret.
  3. Review the headline output first, then inspect supporting metrics.
  4. Run at least one conservative and one aggressive scenario.
  5. Use outputs to set your next training or nutrition action for the week.
  6. Save or share this setup if you want to revisit it later, then check one easier and one harder version before you change your plan.
Questions people usually ask
Can I use yards instead of meters?

Yes. The calculator supports both meters and yards, and always returns pace for both 100m and 100yd so you can compare workouts.

What if I only know laps and pool length?

Switch to laps mode and enter lap count plus pool length. The calculator converts that into total distance automatically.

How is SWOLF estimated?

SWOLF is estimated from your pace, distance, stroke type, and pool length assumptions. It is a planning estimate, not a replacement for watch-based stroke counts.

What does the effort zone mean?

Effort zone classifies pace intensity from Recovery to Sprint using your pace per 100m. It helps you align sets with easy, tempo, threshold, or sprint work.

Is this tool free and private to use?

Yes. AI Fit Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.

Do these tools replace medical guidance?
