Nation's Triathlon 2012 route: Race route to snake through D.C., Maryland

The 2012 edition of the Nation's Triathlon is taking place on Sunday morning, and some of the region's elite athletes are set to swim, bike and run through the streets and waters of Washington and Maryland.

The race, which encompasses a 1.5-kilometer swim in the Potomac River, a 40-kilometer bike ride and a 10-kilometer run, will begin at 7 a.m. in the shadow of the Lincoln Memorial.

From there, racers will embark on a 40K bike ride up the Potomac Freeway, through Georgetown and up Canal Road and the Clara Barton Parkway, to just past the Capital Beltway and back.

The final leg of the race starts on Independence Avenue, where the 10K run will take participants around Ohio Drive in West Potomac Park. It finishes up on the south side of the Franklin Delano Roosevelt Memorial.

Drivers in the area should be alert for major road closures throughout the race area during the course of the event. The above map displays the bicycle race route in red and the 10K run in blue.
