The swim course this year will be the same as last year, both for the sprint distance (750 meters) and the Olympic race (1500 meters).
The MTS run course this year will be the same as last year. For the Olympic run, instead of proceeding through the finish line after the first out and back (what the sprint racers do), there will be a well-marked U-turn before the finish, which will direct Olympic racers to head out for a second lap.
Sprint (3.1 miles, 5 kilometers)
Olympic (6.2 miles, 10 kilometers)
