PURPOSE: To determine if the 5K run age and weight Handicap (5KH, previously developed by the present authors) eliminates the age and weight bias for male and female runners.

METHODS: We recorded age, run times (RT) and weight values for 275 men and 126 women at two regional 5K races. We then used the 5KH to calculate each runner's RTadj, the run time corrected for age and weight. The correlation coefficients between age & weight vs. RT & RTadj were used to assess the extent to which bias was removed by the 5KH. To avoid the confounding effect of effort, we also examined sample subsets consisting of faster runners.

RESULTS: When all runners were considered, the 5KH did not appear to reduce or eliminate age or weight bias for women but did for men. When slower runners (i.e., joggers, or “fun” runners) were removed from the sample, the age & weight vs. RTadj correlations approached zero for both genders, compared to the corresponding correlations with RT which were significantly greater than zero.

CONCLUSIONS: The 5KH appears to remove the biases associated with age and weight for men and women.
