Average Lap Speed Formula

The following equation is used to calculate the Average Lap Speed.

ALS = (TL * D) / (TT / 60)
  • Where ALS is the average speed (for example, mph if D is in miles)
  • TT is the total race time (minutes)
  • TL is the total number of laps
  • D is the distance per lap (miles, kilometers, or meters)

To calculate an average lap speed, multiply the total number of laps by the distance per lap to get the total distance, then divide by the total race time in hours (TT/60 if TT is in minutes).

What is the Average Lap Speed?

Definition:

An average lap speed is the average speed around a circuit, track, or course. It can be computed for a single lap as lap distance divided by lap time, or for multiple equal-length laps as total distance divided by total time.

How to Calculate Average Lap Speed?

Example Problem:

The following example outlines the steps and information needed to calculate Average Lap Speed.

First, determine the total time of the race. In this example, the total time is 10 minutes.

Next, determine the total number of laps. In this example, there were 3 total laps.

Next, determine the total distance per lap. In this case, each lap is 2 miles.

Finally, calculate the average lap speed using the formula above:

ALS = (TL * D) / (TT / 60)

ALS = 3 * 2 / (10 / 60)

ALS = 36 mph
