What is a good swim pace per 100m?

For recreational swimmers, 2:00–2:30 per 100m is typical. Regular squad swimmers often hold 1:30–2:00 per 100m. Competitive swimmers aim for under 1:20 per 100m in freestyle.

How do I improve my swim pace?

Focus on technique first, particularly body position and streamlining. Incorporate interval training (e.g., 10 x 100m with 15s rest) into your sessions. Consistent swimming 3–4 times per week will improve your pace steadily.

Does stroke type affect pace significantly?

Yes, freestyle is the fastest stroke for most swimmers. Backstroke is typically 10–15% slower, breaststroke 15–25% slower, and butterfly varies widely depending on fitness. This calculator is primarily designed for freestyle pace.

How It Works

Your swim pace per 100m is calculated by dividing your total time by the number of 100m segments: pace = total time / (distance / 100). Predictions for longer distances apply a fatigue factor similar to running, recognising that pace slows slightly as distance increases.

Swim Pace Calculation

Pace per 100m = Total Time (s) / (Distance (m) / 100)

Total Time: = Your swim time in seconds
Distance: = Distance swum in metres
Pace per 100m: = Time to swim each 100 metre segment

Predictions for longer distances apply a fatigue exponent of 1.05, slightly less than running (1.06) due to the lower-impact nature of swimming. Results are most accurate for freestyle.
