Abstract: A system for pacing a runner around a running track at a predetermined pace with a moving visual light cue. The system has at least one light strip that is positioned in sight of at least one running lane of a running track, and the light strip has a plurality of light elements that can be sequentially lighted to make it appear as if a single light source is moving along the track at predetermined pace. There is a controller for the light strip that tracks the position of a runner on the running track and selectively light one or more of the plurality of light elements of the light strip in a sequence to have the runner attempt to keep a specific pace. The controller can be dynamically updateable by the runner, and multiple systems can be used to track the runners.
