The Chautauqua Striders Winter 5K Series is a fun (and freezing!) “age-graded” race series, with races starting and finishing at the Chautauqua Harbor Hotel. Age-grading levels the playing field for all runners, just as a handicap is intended to do in bowling and golf. The age-grading system calculates points by providing each runner with a percentage value of an “ideal” or best time based on their age and gender.
