Guam Football Associations organizes various annual leagues for youth athletes, female youth athletes and adult athletes. Each summer, a Co-Ed Masters League also is featured. To participate in leagues, interested players need to first register with a club and then register with Guam Football Association. Starting from 2020, all registration – both with participating clubs and with GFA – are done online via PowerUp Sports. Once registered with both club and GFA, club team administrators are able to build Match Day rosters using the PowerUp app.
In one year, two youth leagues are held – the Triple J Auto Group Robbie Webber Youth Soccer League spring season beginning mid February and the fall season beginning mid September. Close to 3,000 participants play for 13 different club teams annually – Crushers FC, Dededo Soccer Club, ASC Trust Islanders, Quality Distributors Football Club, NAPA Rovers Football Club, Sidekick Soccer Club, Southern Cobras, Southern Heat, Bank of Guam Strykers, Tigers, Tumon Typhoons Football Club, Wings Football Club, and the Guam Shipyard Windward Wolverines.
For adult athletes, various leagues for players of different skill levels are coordinated by GFA. Particularly for men’s teams, an 11-A-Side league, a futsal league, and a beach soccer league are organized by the GFA Football Events Department. Beginning in 2024, the Budweiser G-League replaced the Budweiser Soccer League for men’s teams. A separate GFA Masters League was also created following the creation of the new G-League. Men’s teams have also taken part in futsal and beach soccer leagues during the year.
Beginning in 2024, the Bud Light G-League Women replaced the Bud Light Women’s Soccer League as Guam’s top-flight domestic league for women’s football. Recreational leagues, played twice yearly, are the GFA Women’s Recreational League and the GFA Soccer Moms League.
In addition to the adult leagues, Guam Football Association also organizes the annual GFA Cup tournament for both the men’s and women’s teams, the Bank of Guam GFA Cup and the Jamaican Grill Women’s GFA Cup, respectively. The tournaments were last held in 2019 and have since been temporarily suspended following the COVID19 pandemic in 2020.
In the summer, Guam Football Association organizes the GFA Co-Ed Masters Soccer League, the only adult league that combines both male and female players. Male players need to at least be turning 40 years old in the calendar year of the league, while female players need to at least be turning 30 years old in the calendar year of the league. A minimum number of women must be playing at all times or the team receives a penalty.
