THE COMPETITION

The Olympic triathlon consists of a 1.5 kilometres open-water swim around Farm Cove in Sydney Harbour, a 40 kilometres cycle and a ten kilometres run around the Opera House, Royal Botanical Gardens and Domain. The three elements follow on one from the other without rest.

Swimming is the first sport, making for a spectacular mass start off a pontoon into the harbour. The swimmers follow a triangular course marked out by buoys and ropes, and face penalties if they cut any corners; sinners must stop for 30 seconds. Any stroke is allowed but freestyle is the fastest and therefore most common. Indeed other strokes are rarely seen at world level.

The cycling section follows swimming. There are six stations to handle punctures, and competitors are allowed to carry their bikes to those stations in case of need. Pelotons used to be banned, a "drafting zone" ten metres long and three metres wide observed by riders. This became impractical, however, and cyclists do ride close to each other these days. Sitting on a rival's back wheel without taking a turn in front is, however, frowned upon.

The running section finishes the race, with normal road running race rules applying. Cycling and running follow a similar course; from the Opera House, athletes will head around the shores of Farm Cove to Mrs Macquarie's Chair, where they head along the edge of Woolloomooloo Bay, through the Domain, past the Art Gallery of New South Wales, up to Hyde Park, down Macquarie Street, passing the State Parliament and State Library buildings, to Circular Quay and back to the Opera House. The cycle is six laps and the run two laps.

During the cycling and running legs, a race official may issue a warning with a yellow card. The athlete must stop and await the official's word to continue. For more dangerous or repeat offences, an athlete can be disqualified with a red card. Two yellow cards during a race results in a red card and automatic disqualification.
