A year ago this month, Bears running back David Montgomery’s quest to get faster brought him to a most unusual place: the Burr Ridge home of a Hinsdale Central U.S. history teacher.
Chris Korfist runs a speed school from his house, which has track numbers painted on his long driveway and a not-too-busy street in which to run. His non-traditional approach uses slow-motion cameras and computers to capture runners’ gaits, frame-by-frame, then uses physics to optimize them.
Montgomery, who visited Korfist on the recommendation of teammate Thomas Ives, wanted to increase his top-level speed and try to outrun cornerbacks chasing him on an angle.
