Average Speed of a Marathon Runner

The Average Speed of a Marathon Runner computes the average speed of a runner over a distance (e.g., length of a marathon) based on the distance and the time.

INSTRUCTIONS: Choose units and enter the following:

• (D) Distance Run (default 26.2 miles)
• (T) Time

Average Speed (V): The average speed is returned in both miles per hour and kilometers per hour.

The Math / Science

The formula for average speed of a marathon runner is:

V = D/T

where:

• V = Average Speed
• D = Distance Run (26.2 miles)
• T = Time to Run Distance
