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.
