An athletic device is worn by a participant during an athletic event (e.g., a race). In one example, a race course is provided with a plurality of mats or signal devices along the race course. The mats may have antennas and generate a magnetic field. The device may include a chip system having an RFID tag and a display. As the participant progress along the course, the tag is triggered at each mat and race data may be displayed on the device. Data relating to a location of the participant may also be provided to the participant during the athletic event.
