Sunday was Ethiopia's day in Chicago as Tsegaye Kebede and Atsede Baysa won the men's and women's races, respectively.
Kebede won in record fashion, crossing the finish line at an unofficial time of 2:04:38. It's the fastest Marathon recorded in the United States, which was 2:05:05 set last year by Geoffrey Mutai in New York.
Kebede is the first Ethiopian man to win the Chicago Marathon. His win also breaks the nine-year winning streak held by Kenya.
Supporters from around the world crowded the city streets to cheer them on.
The cheering stations had signs in foreign languages, flags and other activities to welcome international athletes who are running the race. Chicago Sister Cities expects runners from more than 100 different countries.
Cheering stations were organized by places like Osaka, Japan; Lucerne, Switzerland; and Vilnius, Lithuania.
