Other information: This race is Bunion Derby Race #3. Age and gender handicaps are calculated based on the age-graded tables established by World Masters Athletics, formerly known as the World Association of Veteran Athletes (WAVA). Since there are no tables for the 4-Mile distance, the handicaps were based on the mean differential set forth in the tables for 5 Kilometers and 8 Kilometers. The performance level used for these calculations was 75 percent, defined as "regional class." Those who would like to calculate their own age-graded performances for standard distances can download a WAVA age-graded calculator through the Running Times Web site. These tables have been revised over the years, so it is possible that there will be minor revisions for next year's race.
