Abstract

A system and method for determining and tracking a location of a participant traveling along a route wherein the participant being tracked with an RFID tag during an event. The system includes a tag reader system receiving one or more tag reads from the RFID tag, determining a time for each tag read, identifying the tag number of the RFID tag, and transmitting a tag read message including at least a portion of the received tag reads with the tag number and the determined times. A timing system is configured for receiving and storing the tag read message including the tag number from the tag reader. A location device that is associated with the RFID tag of the participant has a location data receiver for receiving location data from a location providing source, and a wireless communication interface. The location detection device receives location information from the location providing source, time stamps each received location information, and transmits tag location data over the wireless interface. A location detection device that is in at least periodic wireless communication with the location device receives the transmitted tag location data, and transmits the received location data to the timing system. The timing system stores the location data and associates the location data with the RFID tag number as provided by the RFID tag reader from at least one of the tag reads from the tag associated with the location device.
