A device (10) that measures the distance traveled, speed, and height jumped of a person while running or walking. Accelerometers and rotational sensors are placed in the sole of one shoe along with an electronic circuit that perform s mathematical calculations to determine the distance and height of each step. A radio frequency transmitter (12) sends the distance and height information t o a wristwatch or other central receiving unit. A radio frequency receiver (14 ) in the wristwatch or other unit is coupled to a microprocessor that calculat es an output speed based upon step-distance and elapsed time, and the distance traveled of the runner from the sum of all previous step distances. The outp ut of the microprocessor is coupled to a display (18) that shows the distance traveled, speed, or height jumped of the runner or walker.
