The European Forces Swim League (EFSL) was formed in the summer of 1975 as an outgrowth of U.S. and Allied Armed Forces community sponsored swim teams. The League was created in response to a recognized need to provide an organized competitive swimming program for the youth of military and civilian members stationed in Europe.  The EFSL is not intended to be competitive with, or draw participants from the local, regional or national European competitive swimming programs. 

The original teams of the EFSL were Berlin, Heidelberg, Lahr, Mannheim, Stuttgart and SHAPE of which Berlin, SHAPE and Stuttgart remain active. Since then the League has steadily increased in membership to 18 teams located in Germany, Belgium, Italy, Portugal, Spain, England and The Netherlands. American and NATO communities are represented. 

The EFSL has six competitive age levels: 8 and under, 9/10, 11/12, 13/14, 15/16 and 17/19. Each level provides a stepping stone for a swimmer to progress through successive levels of competition.  Teams which are located with Department of Defense schools also can have HIgh school teams in accordance with the EFSL Memorandum of Undestanding with DoDDea.

The first annual EFSL Championship Meet was held on 16 April 1977. It has been held annually in the spring.  A Long Distance Championship has been added to the League schedule and is held anually in the fall.  Since then, these exciting events have been the highlights of the League’s long distance and regular seasons.  In February 2018, the EFSL Championship was held at the London Olympic Aquatic Centre with the participation of over 560 swimmers and their families.  

The EFSL is proud of its past achievements in providing a successful program for the personal development of our young people. It recognizes the support and efforts of swimmers, parents, coaches, officials, board members,  sponsors, friends and community organizations without whose assistance these accomplishments could not have been achieved.


The EFSL remains committed to supporting the youth of our communities
through healthy competition and the fostering of the ideals of good sportsmanship.
