2013 US Swimming National Championships: Day 2
The United States Swimming National Championships are held annually, organized by USA Swimming and held in a long course pool. In the past, and as recently as 2007, there were 2 meets annually: and Spring and Summer Nationals. The Spring meet began as a 25-yard (short course) meet, while the Summer meet was long course. Prior to USA Swimming’s creation in the late 1970s, the meet was run by the AAU.
