Each day of the Tokyo Games, NBC Olympics will provide a rundown of the biggest athletes and the biggest events to watch across a variety of sports. Every single event can be streamed live on NBCOlympics.com and the NBC Sports app, and many can also be seen on the television networks of NBC. For even more events, visit the Olympic schedule page to find listings for specific sports or TV networks.

A showdown between Sydney McLaughlin and Dalilah Muhammad, the Olympic debut of park skateboarding and knockout rounds in multiple sports highlight the action on Day 12 of the Tokyo Games. Here's a look at what to watch throughout the evening and into the morning.

Primetime on NBC

Tuesday night's primetime Olympic coverage on NBC will include track & field, gymnastics, and diving. The highlights of the night will be the coverage of the women's balance beam final, which features Simone Biles' return to competition alongside all-around gold medalist Suni Lee, and the live airing of the women's 400m hurdles, which is expected to be a showdown between American stars Sydney McLaughlin and Dalilah Muhammad.

The women's golf competition kicks off from Kasumigaseki Country Club on Day 12. The Americans field strong competitors, including Women's PGA Championship winner and world No. 1 Nelly Korda alongside her sister Jessica Korda. Lexi Thompson and world No. 5 Danielle Kang round out the U.S. contingent.

South Korea's Inbee Park looks to repeat in the women's tournament five years after claiming gold in Rio. Park's recent March 2021 victory in the Kia Classic pushed her past $17 million in career earnings, but she hasn't won a major since 2015.

Three more track finals will run in the second session, and the U.S. will have medal contenders in all three: Emma Coburn in the women's steeplechase, Clayton Murphy in the men's 800m, and reigning world champion Noah Lyles in the men's 200m.

In the field events, the men's hammer throw final is on deck, and the heptathlon and decathlon get underway.
