YMCA of the USA (Y-USA), the national resource office for the nearly 2,600 YMCAs across the country, will celebrate the 100th anniversary of the YMCA National Short Course Swimming Championship, April 3rd through the 7th in Greensboro. Over the past 100 years, the event has played host to thousands of swimmers – many who have gone on to compete at the collegiate, professional and masters levels, as well as in the Olympic Games, where several have brought home medals.
