Calculate swim times from pace

When you know your pace per 100m, you can estimate times for longer distances. This calculator converts your 100m pace to 400m and 1500m times plus speed.

400 metres

400m is a popular middle distance taking 6-10 minutes for recreational swimmers. At 1:45/100m pace, 400m takes about 7 minutes.

1500 metres

1500m is the longest individual pool race and sprint triathlon swim distance. At 1:45/100m pace, 1500m takes about 26.25 minutes.

Pace and speed

A pace of 1:45/100m equals about 3.4 km/h. Most swimmers have a slightly slower pace on longer distances.

Frequently Asked Questions

Can I maintain the same pace for 1500m as 100m?

No, most swimmers are 10-20% slower on 1500m than 100m. With good endurance, you can minimise the drop to 5-10%. Interval and endurance training improve pace maintenance.

What is a good 400m time?

For recreational swimmers, under 8 minutes is good, and under 7 is very good. Beginners are typically 8-12 minutes. Competitive swimmers are under 6 minutes, elite under 4.

How do I improve my pace?

Focus on technique: streamlined body, efficient arm pull, regular kick and good rotation. Mix long steady swims with interval training. Use pull buoy and fins for drills. Consider swim lessons for technique feedback.
