An apparatus comprised of a processor, an actuator portion and a display portion is disclosed. The processor is comprised of a global positioning satellite integrated circuit. The processor is adapted to determine an initial position from a first satellite signal in response to an actuator element of the actuator portion and to determine a distance travelled from the initial position in response to a second satellite signal. The processor outputs the distance travelled from the initial position to the display element of the display portion. The processor receives a goal distance and the processor determines a distance remaining which is the difference between the goal distance and the distance travelled, and outputs the distance remaining to the display element of the display portion. A clock is provided for determining elapsed time and other timing variables. The processor sets an elapsed time variable to zero in response to the activation of the actuator element of the actuator portion and outputs the elapsed time to the display element of the display portion at various intervals or as the elapsed time is changing. The processor is adapted to divide the distance travelled by elapsed time to determine the rate of travel and to divide the distance remaining by the rate of travel to determine a time to finish and these variables are preferably output to a display element of the display portion. The processor, the display portion, and the actuator portion are preferably incorporated into a head piece of a watch. The watch also includes a watchband which is connected to the head piece.
