Getting around on Sunday may take a little longer than usual as roads are being closed for the Nation’s Triathlon and a street festival while Metro works on some of its tracks.

The Fourth Annual Nation’s Triathlon, which includes a 40-kilometer bike course, a 10-kilometer run and 1.5-kilometer swim in the Potomac River, is closing roads around Southwest D.C. and Georgetown for the 7 a.m. to 1 p.m. race.
