Calculate your swim time

This calculator estimates your total swim time for a given distance based on your pace per 100m. Enter your distance and pace to see how long it takes.

Popular distances

Popular distances include 400m (warm-up/test), 800m (half ironman), 1500m (Olympic triathlon), 1900m (half ironman open water) and 3800m (full ironman). Recreational swimmers typically swim 1000-2000m per session.

Pace and fatigue

Your pace typically slows 5-15% over longer distances due to fatigue. Good endurance training and technique minimise this drop.

Using swim time in training

Know your swim time to set realistic goals and plan training. For triathletes, knowing swim time is crucial for race strategy.
