• Highlighting the success of local athlete Katie Ledecky
• Katie Ledecky and the U.S. 4×200 relay team won the gold medal Wednesday, to the surprise of no one. Since the event became a part of the Olympics in 1996, the Americans have won five of six. Ledecky anchored a squad that included Allison Schmitt, Leah Smith and Maya DiRado to a 1.84 second victory over Australia, the only other country to triumph in the event at the Summer Games. Canada was third. The Americans were trailing by 89-hundredths of a second when Ledecky hit the water. She split 1 minute 53.74 seconds, to stop the clock at 7:43.03.
