Pool to Open water
Estimate open-water time from pool pace. Adjustable estimate.
Estimated open-water time—
Estimated pace · per 100—
Estimate, not exact: lost push-offs (~0.7s/turn), sighting and wetsuit buoyancy. Tune to your own data.
Why is open-water swimming slower than pool swimming?
You lose the push-off from each wall, add sighting time to navigate, but may gain speed from wetsuit buoyancy.
Is this an exact formula?
No — it's a tunable estimate. Adjust sighting penalty and wetsuit benefit to match your own race-day data.
