Work out cycling race average speed instantly with clear inputs, formula shown and shareable results.
Average speed is distance divided by elapsed time, and pace is the inverse expressed as time per kilometre. Cycling power rises roughly with the cube of speed against air resistance, so a 10% speed gain on the flat costs about a third more power.
Average speed
speed = distance / time
Pace
pace per km = time in seconds / distance in km
speed = distance / time. Average speed is distance divided by elapsed time, and pace is the inverse expressed as time per kilometre.

Enter distance covered, time taken. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
