Course

The course goes clockwise from the start heading south towards the rowing course. Prior to the rowing course you turn right at the large yellow turn buoy. You then swim parallel to the rowing course till they reach the next large yellow turn buoy past the island where the 1000m rowing sign is. Turn right toward the lagoon and then back to the start/finish to pass between the 2 buoys at the start/finish and then repeat the course.  

On the last leg swim toward the spot where the start finish/turn buoy is, look for the White Meridian Marquee and Black Start/Finish Arch on the shore. For the finish area, you must pass between the two buoys close to the shore before exiting the lake through the finish gate.
