Long Race Calculator

This calculator requires the use of Javascript enabled and capable browsers. This script returns conversions for generally used long race distances for humans. It also computes the AVERAGE speed of the race in both miles per hour and kilometers per hour if you correctly enter the length of the race, and if the official time of the race is entered. Select the distance factor of the race and then enter the value of the factor. For instance, if the race is 26 and a quarter miles, select miles and enter 26.25 as the value. If the race is 50km, select kilometers and enter 50. Fractional parts of a factor should be give in decimal values. A table is given (below the calculator) for such entries. Enter the Official time of the race in days, hours, minutes and seconds as applicable. Click on the Calculate button for the results.

This calculator is designed for very long races such as marathons, ultra-marathons, bicycle races and cross-country events. The important factors are the length of the race or course and the official time. Since there are NO standards for distances or the time for timed events, included are both American and metric options.
