Jānis Daliņš was the first Latvian to win a silver medal in Olympic games, in 50 km walk in 1932 Summer Olympics. He also won European Championships in the same distance in 1934 and set world records in several walking distances. Daliņš' success made race-walking one of the most popular athletics disciplines in Latvia, with two more Latvians winning Olympic medals: Adalberts Bubenko in 1936 Summer Olympics and Aigars Fadejevs in 2000 Summer Olympics.
