Olympic swimming 2016 live stream: Time, TV schedule and how to watch Sunday’s events online

Katie Ledecky, one of the biggest stars for the United States entering Rio, will make her first appearance at the 2016 Olympics on Sunday. The surprise winner of the 800-meter freestyle at the 2012 Olympics in London at age 15, Ledecky is expected to come up big this month.

The first session of the day for swimming begins at noon ET and all of it will be streamed live by NBC Sports. Ledecky will be racing in heats for the women’s 400-meter freestyle. Additionally, there will be heats for the men’s and women’s 100-meter backstroke, men’s 200-meter freestyle and men’s 4x100-meter freestyle relay.

Medals will be handed out in the second session, which begins at 9 p.m. ET.

The women’s 400-meter freestyle finals will be one of the key events in the night session, along with finals for the women’s 100-meter butterfly, men’s 100-meter breaststroke and men’s 4x100-meter freestyle relay. Ledecky already holds the world record in the 400-meter freestyle, so she’s heavily favored to make it through the heats and win gold in that event Sunday.

All of it will be streamed live by NBC Sports, and with Ledecky being one of America’s brightest stars in Rio, you’ll want to catch her in one of her best events. Here’s how to watch all of the Olympic swimming action on Sunday.
