1. An RFID bib detection system comprising at least one tower located at a side boundary of a course, the side boundary being generally perpendicular to a line crossing the course, the tower supporting an antenna having a ninety degree zone of detection wherein the antenna is pointed at an angle of approximately forty-five degrees relative to said side boundary and to said crossing line for detecting RFID bibs of participants that pass through said zone;
wherein said antenna faces toward participants approaching said crossing line such that an edge of said zone of detection is along said crossing line;
wherein a last read for each RFID bib in said zone reflects a time when such bib crossed the line;
wherein said antenna faces toward participants moving away from said crossing line such that an edge of said zone of detection is along said crossing line; and
wherein a first read for each RFID bib in said zone reflects a time when such bib crossed the line.
