1. In a process, for determining information pertaining to movement factors in running disciplines and values derived therefrom, particularly information concerning stride length, stride rate, stride time and running time, with a pair of running shoes, each shoe of which contains a transmitter and a receiver, of the type wherein a first one of said shoes, upon contacting the ground, emits a first output signal to a second one of said shoes, said first signal being triggered by a ground contact sensor, and wherein the receiver contained in said second shoe receives said first signal and emits a reflected output signal via the transmitter of the second shoe to the receiver of the first shoe, whereafter the first shoe emits a second output signal to a remote receiver that is linked with a computer unit, and wherein a determination of desired information is computed and displayed by the computer unit data based on the relative timing of the first and second signals, the improvement comprising the additional steps of activating a first counter when said first shoe contacts the ground and deactivating said first counter in response to receipt of the reflected output signal by the receiver of the first shoe;

  • activating a second counter when said second shoe lifts off at the ground by a sensor built into said second shoe and deactivating said second counter in response to receipt of the first output signal from the first shoe by the receiver of the second shoe;

    emitting a value determined by the second counter to the receiver of the first shoe; and

    utilizing readouts from said counters in said determination.
