What each input means

Your Age
Your current age in years. Performance naturally declines with age; the calculator adjusts for this.
Gender
Biological sex for age-grading standards. Men and women are graded against their respective world-class standards.
Race Distance
The distance of the race you completed.
Finish Time Hours
Hours portion of your finish time.
Finish Time Minutes
Minutes portion of your finish time.
Finish Time Seconds
Seconds portion of your finish time.

What each result means

Age-Graded Score
Your performance as a percentage of the world-best for your age and gender. 60%+ is competitive, 80%+ is national level.
Age Factor
Multiplier reflecting age-related performance decline (1.0 = peak age).
Equivalent Open-Age Time
What your performance equals if you were at peak age.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Your Age = 40, Gender = 0, Race Distance = 1, Finish Time Hours = 0 = 6 input(s) provided
  2. Calculate Age-Graded Score
    Age-Graded Score
    53.9 = 53.9
  3. Calculate Performance Level
    Performance Level
    Recreational = Recreational
  4. Calculate Age Factor
    0.936 = 0.936
