Dayli Cooper

Dayli Cooper (Camagüey, Cuba, ca. 2002) is a Cuban middle-distance runner specializing in the 800 and 1500 meters. At 24 years old, she is considered one of Cuba's most promising young talents in middle-distance athletics.

In 2025, she competed at the World Athletics Championships in Tokyo, clocking 1:58.16 in the 800 meters.

In 2026, she opened the season with a standout performance at the Znamensky Memorial in Russia, setting a new personal best of 1:58.03 and winning the event.

On June 29, 2026, she produced the finest performance of her career, winning double gold at the Pan American Athletics Championship in Medellín, Colombia — first the 1500 meters, then the 800 meters with a time of 1:56.10 minutes, a new personal record. That mark places her third on Cuba's all-time list in the 800 meters, behind the legendary Ana Fidelia Quirót (1:54.44) and Zulia Calatayud (1:56.09). Both victories secured her direct qualification for the 2027 Lima Pan American Games.
