So you are a more mature runner (that mean older, dude!) and your time is not as good as the younger set. Ever wonder, in any given race, what you might have done if you were 25 and not your age? Need a little help to deal with those younger runner friends who are "polite," but give you the "gaze" when they finish before you? Check out the Flyer Handicap Calculator developed by University of Dayton, Ohio runner and physiologist Paul Vanderburgh.
