Four-time Olympic gold medalist Simone Biles is set to make her 2021 debut at the U.S. Classic on May 22 in Indianapolis. 

Biles, 24, hasn't competed since picking up five gold medals at the 2019 World Gymnastics Championships. She initially planned to return to competition at the artistic gymnastics All-Around World Cup stop in Tokyo on May 4, but the event was canceled. 

After landing two new signature moves at Worlds, Biles is planning to further push the boundaries of the sport in the near future. During her break from competing, she developed a new skill, the Yurchenko double pike vault. No woman has previously attempted the move in competition, but Biles said in April that she plans to debut the vault before the Tokyo Olympics. 

The U.S. Classic serves as a qualifier for the 2021 U.S. Gymnastics Championships, scheduled for June 3-6, which in turn determines qualifiers for Olympic Trials. Also among the field at the Classic will be 2008 Olympian Chellsie Memmel, 32 -- who hasn't competed since 2012 -- and two-time Olympic medalist Laurie Hernandez.
