Do you aspire to be a ranked runner? Here is information you need to convert your race distance to a 10K equivalent time.

The Formula
The Washington Running Report Runner Rankings converts all race times to 10K equivalent times to allow "apples to apples" comparisons between race performances. We acknowledge that all races and race courses aren't created equally, and take that into account in making the comparisons.

To calculate your equivalent time value, first convert your clock time to seconds. Next, if your distance is less than 10K, multiply your figure by the corresponding number on the chart.

Example: A woman running a 21:47 5K race:
(21 x 60 + 47) = 1307 seconds
1307 seconds x 2.082 = 2741 seconds
2741 seconds / 60 = 45:41 in clock time = 10K equivalent.

If the distance is longer than 10K, divide your figure by the number on the chart

Example: A man running a half-marathon in 84:50:
(84 x 60 + 50) = 5090 seconds
5090 seconds / 2.204 = 2309 seconds
2309 seconds = 38:29 in clock time = 10K equivalent.
