Early Prototype This project began with the kernel of an idea and 400 meters of LEDs. Early prototypes demonstrated the viability of a master-slave architecture.

Scaling Up, Literally As we considered fully laying out our 400-meter prototype, we saw that it was much too large to be installed in our office. To test TrackPacer at scale, we mounted every LED to a conference room wall in 5m spools.

Verifying Pace We ventured to an indoor track to calibrate TrackPacer and to ensure pace was accurate. We backlogged enhancements like saving workouts and running multiple pacers concurrently until we proved the core tech.

Taking it Outside Feedback from both coaches and athletes was critical for TrackPacer's development. This couldn't happen inside a lab so, in collaboration with the University of Colorado Boulder, we installed TrackPacer at Potts Field for runners to test.
