So far, it's been hard to top the first four days in the pool, where Michael Phelps and Katie Ledecky picked up more gold on Tuesday night to help keep the United States well in front of the overall medal race. Take a look below to find out where the Team USA storylines and medals may come on Day 6 (times ET and available for live streaming event coverage on NBCOlympics.com).

Wednesday, Aug. 10

Marquee events highlight the evening action in the pool and in gymnastics, where the men's gymnasts begin their individual competition with the all-around final (3 p.m.). The sting of a disappointing finish in Monday’s team final could be taken away by Chris Brooks and Sam Mikulak earning medals here.

Earlier in the day, preliminary round swimming includes Ryan Lochte’s first individual swims of the Games in the 200-meter individual medley, which also happens to feature Phelps. They’re in separate heats, however, with Lochte in Heat 3 (1:19 p.m.) and Phelps in Heat 4 (1:24 p.m.), both eyeing one of two primetime semifinals (10:29 p.m., 10:38 p.m.).

As with every itinerary in Rio before, this day begins more than 12 hours earlier, of course.

After four days of rowing heats, medal events loom closer on the horizon for Team USA’s rowers, and it will be an early start at Lagoa Stadium, including for Felice Mueller and Grace Luczak in one of two women’s pairs semifinals (7:30 a.m.). A half-hour later, Kate Bertko and Devery Karz will compete in one of four semifinals heats (8 a.m.). On the men’s side, Joshua Konieczny and Andrew Campbell will have their oars in the water for one of four semifinals in lightweight double sculls (8:10 a.m.). Men’s eights repechage will also include Team USA (9 a.m.). The Team USA foursome of Adrienne Martelli, Megan Kalmoe, Tracy Eisser and Grace Latz will have their chance to medal this morning, too, as they reached the women’s quadruple sculls final (9:34 a.m.).

Also early, in road cycling, medals will be contested on both the men's and women’s sides, beginning with the women’s individual time trial (7:30 a.m.), which saw Team USA's Kristin Armstrong earn gold in both Beijing and London. Armstrong is back for Rio, along with Evelyn Stevens, a former I-banker who earlier this year set a UCI record for the most distance covered in an hour. The men will also take to the picturesque course in Rio for the men’s individual time trial (9 a.m.), featuring Brent Bookwalter and Taylor Phinney.

Team USA equestrians return to the Olympic Equestrian Center to begin their run for a dressage medal with the Grand Prix Day 1 (9 a.m.).

After a loss to Austria in their opener, Jake Gibb and Casey Patterson will meet Spain to keep alive Team USA’s hopes for two beach volleyball medals in Rio. Gibb and Patterson play at 10 a.m.

Glenn Eller qualified for Rio nearly a year ago, and he’ll have his chance, in his remarkable fifth Olympics, to win another shooting gold today. Eller, who won gold in the Beijing 2008 Games, and Joshua Richmond will begin their day in qualifying rounds (8 a.m.), with semifinals slated for 2 p.m.). Should they move on, the men’s double trap final takes place in the afternoon (2:25 p.m.).

Team USA archery storylines abound again today, as Zach Garrett looks to advance (3:18 p.m.) a day after his fellow Rio team silver medalists, Jake Kaminski and Brady Ellison, had to meet each other in a knockout round, which Ellison won. Garrett and Ellison, the event’s No. 2 seed, may be on a collision course, too. Ellison’s next match will take place Friday (9:31 a.m.).

While gold will have eluded both Williams sisters in their singles and doubles efforts, Venus Williams, along with Rajeev Ram, opens her mixed doubles tournament play in Round 1 (10 a.m.). In men’s doubles, Steve Johnson and Jack Sock remain in the medal hunt, having advanced to today’s semifinal match (1 p.m.). Sock and Bethanie Mattek-Sands are Team USA’s other mixed doubles pair, and they’ll play Great Britain in Round 1 (4 p.m.).

For Caleb Paine, who made his Olympic debut on Tuesday, Race 3 dawns in men’s Finn sailing prelims (12:05 p.m.). Race 4 will take Paine to a 1:30 p.m. start, which would be followed by sails Thursday, Saturday and Sunday to set up the Aug. 16 final. In men’s Laser, Charlie Buckingham, who is the highest placed U.S. athletes here represents Team USA today in Race 5 (12:05 p.m.). Also at 12:05, Team USA will carry high medal hopes into men’s 470, with Yale alum and three-time Olympian Stu McNay and Dave Hughes. For the women, Annie Haeger and Briana Provancha also carry 470 medal hopes into today’s action (12:05 p.m.). In Nacra 17, Bora Gulari and Louisa Chafee represent Team USA, beginning with Race 1 (12:05 p.m.). Two-time Olympian Paige Railey is back on the water, too, for women’s Laser Radial races (12:15 p.m.).

Today in judo, Colton Brown wakes up with a similar itinerary as his fellow judokas this week, beginning with his first match in the 90 kg. Round of 32 (9:56 a.m.), and his eye on the semifinals (3:12 p.m., 3:19 p.m.). The medal rounds are this afternoon (2:30 p.m.).
