On Tuesday, Mexican-born American runner Leo Manzano won a silver medal in the men's 1,500-meter final, running the fastest time ever by a U.S. athlete at the Games. Manzano, 27, entered the U.S. at the age of 4 without papers, according to LetsRun. He didn't gain legal residency until 10 years later.

"Silver medal, still felt like I won! Representing two countries USA and Mexico!", Manzano tweeted shortly after his win. Most of his tweets throughout the Olympics have been in both Spanish and English.

"I am honored and excited to represent both the United States and Mexico by earning this silver," Manzano told the Associated Press. "Standing on the podium has been a dream of mine and I share it proudly with my family, friends, coaches and all my supporters from Austin, Marble Falls, and Granite Shoals, Texas as well as Dolores Hidalgo, Mexico."

On the track Manzano celebrated with the U.S. flag and the Mexican flag.
