United States Cycling National Championships (historical)

The predecessor of USACycling, the Amateur Bicycle League of America (ABLA) was founded in 1921 and held National Championships starting that year. From 1921 to 1964, these championships were two-, three-, or four-event omniums of track-style events, rather than a road race. USACycling souvenir programs list no results for events in 1931-1934, 1938, and 1942-1944. The 1939 program summarizes the 1937 National Champions. The 1938 results are from a national championship with similar events and format that the Amateur Athletic Union promoted.

Amateur Women

Venues, Dates, and Courses
The omniums were held on a variety of courses including one to three mile loops in city roads and public parks, dirt car and horse-racing tracks, and on a banked, dirt velodrome. Starting in the late 1950s the championships were held on more traditional paved velodromes.
