Overview
When running splits or laps, the true average comes from total distance and time. This tool shows that alongside the fastest and slowest split, a practical way to review pacing.
Formula
Split distances and times are summed, then divided. We do not average paces because splits may differ in length.
How it works
Enter splits
Up to three splits, with distance in km and time in decimal minutes.
Leave unused splits at zero
A split with zero distance or time is ignored.
Read the average and range
A large difference may reflect a fast start, a stop or fatigue.
Worked examples
Two splits: 5 km in 25 and 5 km in 27
Total is 10 km in 52 minutes, speed 11.54 km/h and pace 5:12/km.
Only one split
The tool works, but the average equals that split and the difference is zero.
Frequently asked questions
Why not average the paces?
Splits may have different lengths. The correct average uses total distance and time.
Do stops affect it?
Yes. Stops add time and lower average speed if included in the measurement.
How precise are decimal minutes?
0.1 minute = 6 seconds. Enter 25.5 for 25:30.
Does it work for swimming or cycling?
The math is the same, but check distance units and whether pace suits the activity.
