Abstract: There is described a method and system of measuring, displaying, recording, and storing real-time elapsed times for each athlete to complete predetermined distances or repetitions having multiple athletes within a heat who have common starting time and different stopping times with each heat having different starting times. Trainers use a personal or mobile communication device to measure, display, record, and store elapsed times for each repetition completed by each athlete as well as to create, modify, delete, and display athlete, benchmark set, elapsed time, body count, and power tower data. A software application provides athlete assignments to a heat and a lane, benchmark set selection, timer initiation, and elapsed time measurement, display, recording, and storage for each repetition completed by each athlete. It further provides the user the ability to upload and download data from and to a storage location as well as to perform text or email communications.
