TrackPacer, an LED string for tracks, helps runners train

Kline developed a product called TrackPacer, a “digital track rabbit” that provides constant feedback to help runners reach their desired pace while training. Her goal is to change the way recreational and elite athletes train. TrackPacer is an LED string, installed around the inner perimeter of athletic training tracks, that pulses bands of light at a prescribed speed around the track. Athletes run alongside the light bands to ensure they are controlling the pace of their run.
