Day 7 at the 2012 Summer Olympics offers another full day of medals (22 in all). And it also offers a bit of a unique juxtaposition. As swimming begins to conclude with its penultimate day, one of the Summer Games' most anticipated sports, track and field, opens its competition.
Friday will be Michael Phelps' final time ever swimming for an individual medal at the Olympic Games (he says there is no way he is going to Rio in 2016, despite his mother's pleadings. Of course, he also said he was never again going to swim the 400m IM after Beijing).
What To Watch at the Olympics, Friday, Aug. 3:
Tennis - Semifinals, 7 a.m. - 3 p.m. ET, Bravo
It's another full day of tennis at the Olympics in Wimbledon, with some of the biggest names in the sport in action. After No. 1 seed Roger Federer and Juan Martin Del Potro open men's singles play, Great Britain's Andy Murray will challenge Novak Djokovic for a spot in Sunday's finals. In the women's bracket, it's Victoria Azarenka, the tournament's No. 1 player, against Serena Williams, and then Maria Sharapova taking on fellow Russian Maria Kirilenko.
But wait, there's more! The Bryan brothers are playing in the men's doubles quarterfinals (7:30 a.m. ET), as are the Williams sisters on the women's side. The United States is also represented in the mixed doubles quarterfinals, with Mike Bryan and Lisa Raymond teaming up.
Cycling - Men's Team Pursuit, 12:59 p.m. ET (competition beings at 10:56 a.m. on NBC Live Extra)
If you thought team sprint was wild, wait until you see team pursuit, especially when Great Britain gets going at close to 40 mph.
In team pursuit, teams of four race 16 laps around the track to earn the fastest time. The fun wrinkle: the race is over if one of the teams catches the other.
Athletics - Women's 10,000m, 4:30 p.m. ET, NBC
The first track part of the track and field competition (officially known as "Athletics" at the Olympics) is the women's 10,000m (6.2 miles). Ethiopia's Tirunesh Dibaba, who won both this event and the 5,000m in Beijing, will look to defend her title (an Ethiopian runner has taken gold in the 10,000m three of the six times it has been held). Team USA is represented by Amy Hastings, Lisa Uhl and Janet Cherobon-Bawcom.
Gymnastics - Men's Trampoline gold medal final, 8 p.m. ET (live at 10:26 a.m. on NBC Live Extra)
Did you know trampoline is a real Olympic sport? It is! Qualifying is live on MSNBC beginning at 9 a.m.
Athletics - Men's Shot Put finals, 8 p.m. ET, NBC (live at 3:30 p.m. on NBC Live Extra)
Athletics begins on Friday and the first gold medal handed out could go to the United States. After finishing seventh in Beijing and fifth at the 2011 World Championships, American Reese Hoffa comes to London as the top U.S. qualifier and a medal hopeful. He's joined on Team USA by Christian Cantwell, the 2008 silver medalist, and Ryan Whiting, the 2012 World Indoor Championships winner.
Swimming - Men's 100m Butterfly, 8 p.m. ET, NBC (live at 2:38 p.m. on NBC Live Extra)
The second-to-last day in the pool brings with it Americans Missy Franklin and Elizabeth Beisel dueling in the women's 200m back, Katie Ledecky in the women's 800m free, and the pool's fastest race -- the men's 50m free -- with Team USA's Cullen Jones and Anthony Ervin sprinting for gold.
But the big story is, of course, Michael Phelps. He'll swim in the finals of the 100m fly, and, assuming he's telling the truth, it will be his final individual event ever at the Olympics (though, he is part of the men's 4x100m medley relay on Friday, 3:27 p.m. ET). Tune in to see the greatest Olympian ever go for medal No. 21.
