A system for training athletes in running activities, such as sprints or team field sports, provides a resistance to an athlete attempting to run. The system comprises a drive unit, and in an embodiment, the drive unit comprises a motor having a motor shaft and a pulley operatively coupled to the shaft. The system further comprises a rope adapted to be rolled on the pulley, a unit controller adapted to control operation of the drive unit, and a programmable logic controller, which logic controller may display and storage of data related to the operation of the system. In use, the rope may be fastened to an athlete, and thereafter the athlete may be allowed to run in a direction away from the drive unit, where the pulley will provide a resistive force on the athlete.
