The Tokyo Olympics won’t be anything like the Games you’ve watched in the past. Athletes will be competing with no spectators, without even their families to cheer them on, among other restrictions. These strict on-the-ground rules, will be in effect because of the COVID-19 pandemic that just triggered a new state of emergency for Tokyo. But the global event is moving forward, and roughly 11,000 participants are headed to Tokyo for the Games. Such a massive group of elite athletes are sure to bring thrilling competition, gripping rivalries and moments for the record books.

Here are 48 to watch when the Games formally kick off on July 23.

When the greatest gymnast of all time got the notice in March that every aspiring Olympian was dreading—that the Games were postponed by a year—it hit hard.

“I was angry, I was annoyed, I was sad,” says Simone Biles, the reigning Olympic all-around gymnastics champion. “I had to let myself feel all the emotions. I 100% felt like I didn’t plan this—now we have to go back to the drawing board and deal with a lot of variables. But at the end of the day, this is bigger than me. We have to make sure that everybody in the world is safe.” Still, she adds, “it did suck.”
