Weight Age Grade Calculator
What is my Weight-Age-Graded Time? It is a statistical calculation of your "adjusted" run time (5K, 10K, 1/2 Marathon or Marathon) if you were 25 yrs old and either 110 lbs (F) or 143 lbs (M) based on your actual age, weight and run time. In this calculation, the Flyer Handicap assumes that not only are you lighter but you are also a "scale model" of yourself and are, therefore, shorter.
|What is the science behind this Flyer Handicap? The handicap is based on the documented decline in aerobic function, specifically distance run speed, due to increasing age and fat-free mass. Download the attached PowerPoint presentation for more information. We also have two research papers on the Flyer Handicap. The first, which explains the derivation, is in the March 2007 issue of Measurement in Physical Education and Exercise Science. Click here for a pdf copy. The second, a validation study, is in the December 2006 edition of the Journal of Exercise Physiology (online). Click here for a pdf copy.|
|Note: If you enter age below 25 the Flyer Handicap will use 25 as your age. If you enter weight below 110 lbs or 143 lbs for women and men, respectively, the Flyer Handicap will use 110 lbs if you are a woman and 143 lbs if you are a man. Lower ages and weights than these are, for most runners, generally not an advantage.|
