Average Swim Times
How fast am I? Enter your 100 m, mile, 1500 m, 70.3 or Ironman swim time and compare your pace per 100 with benchmark ranges and published triathlon splits.
Free swim time benchmark. Enter a time for 100 m, 400 m, 1500 m, a mile, 1.9 km (70.3) or 3.8 km (Ironman) and get your pace per 100 m or 100 yd, the rule-of-thumb range it falls in (beginner, recreational, fit recreational, club, competitive), and for 1.9 km and 3.8 km a comparison with published triathlon swim medians. The pool ranges are rule-of-thumb coaching ranges, not measured percentiles; the triathlon numbers come from TriTimes finisher statistics and a 2024 PLOS ONE analysis.
How long does it take to swim a mile? A mile is 1609 m, so the time depends on your pace per 100 m: about 24:08 at 1:30, 32:11 at 2:00 and 40:14 at 2:30. The U.S. Masters Swimming pace chart lists 1650 yards at 41:15 for a 2:30 pace and 33:00 for 2:00. In our rule-of-thumb ranges, a fit recreational swimmer (1:40 to 2:00 per 100 m) takes 27 to 32 minutes and a recreational swimmer (2:00 to 2:30) 32 to 40 minutes.
Is swimming a mile in 40 minutes good? Yes. 40:00 for a mile is about 2:29 per 100 m, a solid recreational pace at the slower edge of our recreational range (a rule of thumb, not a measured percentile). Breaking 35 minutes needs roughly 2:10 per 100 m, and 30 minutes about 1:52 per 100 m. What is an average Ironman swim time? The median Ironman swim (3.8 km) is 1:15:38 across 805,030 finisher results from 2002 to 2026 (TriTimes), about 1:59 per 100 m.
A peer-reviewed analysis of 687,696 age-group finishers (Knechtle et al., PLOS ONE 2024) reports mean swim splits of 1:17:21 for men and 1:21:41 for women; means run slower than medians because slow swims stretch the tail. The median IRONMAN 70.3 swim (1.9 km) is 38:39, about 2:02 per 100 m. How fast should I swim 100 m? There is no single right time.
Public data does not rank recreational swimmers, so we use rule-of-thumb ranges per 100 m: under 1:20 competitive, 1:20 to 1:40 club, 1:40 to 2:00 fit recreational, 2:00 to 2:30 recreational, slower than 2:30 beginner. A single all-out 100 m is faster than the pace you can hold for a mile, so a 100 m time will usually land in a faster range than your mile time.
