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,[1][2] 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.[3]
