In 1896, the date of the first modern Olympics, the swimming race started when all the competitors were taken out to the icy waters of the Mediterranean sea in a boat. The winner was the first person to reach the shore. The distance was 1200 metres.
Olympic swimming has come a long way, to temperature-controlled 50-metre pools, wave-killing gutters, lane markers designed to reduce turbulence, and status as one of the Games' glamour events.
