Calculate swim pace per 100m, split times, and finish time for pool and open water events.

Swim Pace

Swim pace is typically measured per 100 meters (or 100 yards in the US).

Common race distances:

  • 50m/50yd: Sprint
  • 100m/100yd: Sprint
  • 200m: Middle distance
  • 400m/500yd: Middle distance
  • 800m/1000yd: Distance
  • 1500m/1650yd (mile): Distance
  • Triathlon sprint swim: 750m (0.47 miles)
  • Olympic triathlon: 1500m (0.93 miles)
  • Ironman swim: 3800m (2.4 miles)

Pace benchmarks (per 100m):

  • Elite swimmer: 0:55–1:10
  • Advanced: 1:15–1:30
  • Intermediate: 1:30–2:00
  • Beginner: 2:00–3:00+
