Just two days away from the opening ceremony of the Olympic Games Tokyo 2020, there is enough pressure and excitement to fill up the pool you and your club train in.

With every Olympic Games comes Olympic records and history, here are a few that you can be on the lookout for as you watch the competition take shape.

Keep the Streaks Alive! 
There are a handful of U.S. swimming streaks on the line at these Olympic Games. Heading into this Olympic Games competition, the U.S. has:

• sat atop the swimming medal table at every Olympic Games competition since 1988
• recorded at least 12 gold medals at every Olympic Games competition since 2004
• posted six-consecutive gold medals in the men’s 200 back
• posted four-consecutive gold medals in the men’s 200 IM
• medaled in the women’s 200 IM in five straight Olympic Games
• medaled in the women’s 400 IM in four straight Olympic Games 

Winningest Olympian Ever? 
Heading into the competition, Katie Ledecky’s five Olympic golds puts her at a tie for No. 12 on the all-time Olympic gold medal list by a female athlete. Throughout history, only one female athlete—Soviet/Ukrainian Gymnast, Larisa Latynina—has ever earned nine Olympic golds. Now, with Ledecky’s four individual events and relay eligibility, she has a chance to join Latynina at the top. When it comes to female swimmers, Ledecky’s five golds are fourth on the all-time list, trailing Jenny Thompson (eight golds), Kristin Otto (six golds) and Amy Van Dyken (six golds). Regardless of the outcome in Tokyo, Ledecky is already known as one of the best swimmers ever, but now has the opportunity to climb the leaderboard. 

Unchartered Territory
Qualified in three individual events each, Caeleb Dressel and Michael Andrew could put themselves in elite territory depending on their results in Tokyo. For Dressel, if he can win the 50 freestyle, 100 freestyle and 100 butterfly, he would become the first person to ever do so on an Olympic stage. For Andrew, he is already the first male U.S. swimmer to compete in those three events in a single Olympiad. If Andrew can medal in the 100 breaststroke, he will join Steve Lundquist as the only male U.S. swimmer to medal in a breaststroke event while having a different individual, non-breaststroke event also on his Olympic resume.   

The Big 3-0
The U.S. currently sits at 28 total medals in both the women’s 100 and 400 freestyle events. Should the U.S. capture two medals in one (or both) of the events, it would be the first time a country has ever reached the 30-medal mark in a women’s swimming event. The fate lies in the hands of Erika Brown and Abbey Weitzeil in the 100 free, and Katie Ledecky and Paige Madden in the 400. To date, the U.S.’ 37 medals in the men’s 100 back and 30 medals in the men’s 100 free are the only swimming events where a country has breached the 30-medal mark.

Redemption Events
The 2016 Rio Olympics marked the first time since 1988 where the podium of the women’s 200 breaststroke did not feature a U.S. swimmer. This summer, it will be up to Indiana Swim Club teammates Annie Lazor and Lilly King to possibly start a new streak. As of July 21, Lazor currently holds the third-fastest time in the world, while King is six tenths behind her with the sixth-fastest time in the world.

On the men’s side, Dressel and Zach Apple are tasked with reclaiming gold in the men’s 100 free. As mentioned earlier, the U.S. has posted an incredible 30 Olympic medals in the event, however the team has only brought home one gold—Nathan Adrian in 2012—since 1992. Dressel currently holds the third-fastest time in the world, trailing the current top-spot holder, Romania’s David Popovici, by nine tenths.
