Abstract
A racing system for a group of exercise machines is disclosed. The race is entirely flexible, in that each exercise unit communicates electronically with all of the other potential racing units. Any user may offer a race, accept or reject another user's race offer, or join a race during a limited countdown period. More than one race can be underway. For cost reduction, a daisy chain hookup is used, in which each unit's microprocessor has an input port receiving message flow from the output port of the preceding unit, and an output port transmitting message flow to the input port of the following unit. The racing function is controlled by the same microprocessor which is embedded in each exercise machine as the controller for that machine, receiving commands from the user and feedback from the machine.
