The U.S. Open Championships were first held in 2012. The event is an international affair where everyone in the ultimate community is welcome to meet, compete and learn.
In 2017, the U.S. Open was combined with the Youth Club Championships (YCC) and rebranded as the U.S. Open Club Championships. YCC has been held at the National Sports Center in Blaine, Minn., every year since it was founded in 2005. With the combination of the two events, the U.S. Open Club Championships is the single-biggest event run by USA Ultimate, with eight divisions, more than 100 teams and more than 3,000 athletes.
USA Ultimate announced in late 2023 that the U.S. Open Club Championships, one of ultimate’s flagship events on the domestic calendar, will be returning to Aurora, Colorado for 2024.
