Typical pace per 100 m
| Swimmer | Pace per 100 m |
|---|---|
| Beginner | 2:30 to 3:00 or slower |
| Regular lane swimmer | 2:00 to 2:30 |
| Club or triathlete | 1:30 to 2:00 |
| Fast competitive | Under 1:20 |
These are rough ranges for front crawl in a pool; breaststroke is usually slower.
Triathlon swim distances
| Event | Swim |
|---|---|
| Sprint | 750 m |
| Olympic (standard) | 1,500 m |
| Half Ironman (70.3) | 1.9 km |
| Ironman | 3.8 km |
Open-water times are usually slower than the pool: there are no walls to push off, you have to sight, and conditions vary. A wetsuit can make you faster.
Frequently asked questions
How do I work out my pace per 100 m?
Divide your time by the distance and multiply by 100. 1,500 m in 32:30 is 2:10 per 100 m.
How many lengths is a mile?
About 64 lengths of a 25 m pool or 32 of a 50 m pool.
Can I use yards?
Yes, pick yards for distance and a 25 yd pool.
How accurate are the predictions?
They assume the same effort and get less reliable over much longer distances.
