The U.S. Swimming year runs from September through July, and the Belmont Aquatic Team competes in both the Short and Long Course seasons. BAT swimmers generally contract with the team for the full year. There are occasional openings to participate during the Long Course season only. This option is sometimes chosen by swimmers who have participated on another team and want to join a U.S. team mid-year.
From September through March swimmers practice and compete in 25 yard pools, which is called the "Short Course" season. The team competes at 10-12 meets between October and February, followed by various championship meets in February and March.
The "Long Course" season follows after a two week break in late March and runs through July. Meets are held at 50 meter pools and are clustered in May-July, followed by various championship meets in late July.
