Abstract: A personal electronic starter and timer has a finish line unit for generating an end of race signal across a finish line of a race of a predetermined distance. A body unit is coupled to a body of a person. The body unit is used for generating a countdown signal and starting a timing function after a start signal, the timing function terminating when the body unit reads the end of race signal generated by the finish line unit.

Abstract: A solo electronic starter and timer system for runners that includes a starter position unit, a finish position unit, and an athlete body unit; the body unit radio transmitter circuit transmitting a stop pulse to the finish position unit in response to the triggering of the body unit radio transmitter control circuit triggered by an optical body unit photo detector circuit; the finish position unit having a micro-controller programmed to time and display the elapsed time between receipt of start pulse by a radio receiver circuit of the finish position unit and receipt of the stop pulse that is generated by the body unit radio transmitter circuit of the athlete body unit.
