Why is average speed not just the mean of segment speeds?

Because you spend more time at slower speeds. If you ride 10 km at 20 km/h (30 min) and 10 km at 40 km/h (15 min), your average is 20 km / 0.75 hours = 26.7 km/h, not 30 km/h.

How many segments can I calculate?

This calculator supports up to 3 segments. Set unused segments to 0 distance to exclude them.

Should I include stop time?

If you want overall average speed including stops, add stop time to the segment. For moving average, only include time when pedalling.

How We Calculate This

Weighted Average Speed

Average Speed = Total Distance / Total Time

For each segment, time is calculated as distance / speed. The total distance is divided by the total time across all segments. This gives a distance-weighted harmonic mean, which correctly accounts for spending more time at slower speeds.
