OPEN WATER SWIMMING
The racers in Open Water Swimming begin together on a pontoon. Each racer has transponders on their wrists so that intermediate times can be measured. These are linked to the Open Water gates that have been installed with antennas. At the finish gate, there are touch-pads, similar to the ones used in the swimming pool, which stop time as soon as a racer touches them. There is also a backup camera system that films the finish of the races in case judges need a frame by frame indication of the result.
