Summary
Enter a total race time with a lap count, or enter each lap time directly, to get per-lap splits, the average lap, and the fastest and slowest lap.
How it works
- Choose "Total Time ÷ Laps" if you only know the finishing time and number of laps.
- Or choose "Individual Lap Times" and enter each lap split separately.
- Type times as seconds, minutes:seconds, or hours:minutes:seconds (e.g. 83.4, 1:23.40, or 1:02:03.5).
- Click Calculate to see the average lap time, total time, and fastest/slowest lap.
- In individual mode, use "+ Add Lap" for more rows or the trash icon to remove one.
Use cases
- Finding the average lap pace for a go-kart or motorsport race.
- Comparing individual lap splits to spot the fastest and slowest laps.
- Working out an even lap pace target from a total goal time before a race.
- Checking swimming pool lap consistency across a training set.
- Reviewing track workout splits to see how much laps varied.
