Swimming Pace Calculator

Calculate your swim pace per 100 meters or 100 yards and predict times for triathlon swim distances. Example: 1,000 m in 20:00 is a pace of 2:00 per 100 m.

Formula and method

Pace per 100 m = time (s) / distance (m) x 100. Pace per 100 yd = time / distance (yd) x 100. Speed (km/h) = distance (km) / time (h).
