  1. It is not necessary to qualify for the Grand Prix to compete in the Equalizer Series.
  2. For each race in the Equalizer Series:
    1. Results will be converted into age-performance percentages (see below).
    2. Each percentage will be converted into a 4-digit number.
    3. This number will be the runner’s score for the race.
  3. Top 4 scores per runner will be totaled, resulting in a final score for the series.

Age-Graded Scoring

Age-graded scoring allows runners of any age and any gender to be compared fairly against each other. If you are interested in the fine details, click here. The official age-grading calculator used by FSRC for the Equalizer Series road races can be found hereand for track races (such as the Summer Decathlon 800m) here.
