The Catholic Youth Organization is a recreational sports program run through the Toledo Diocese. St. Aloysius fields teams in four sports.
- Basketball: boys and girls, grades 3 – 12
- Cross Country: boys and girls, grades K – 8
- Track: boys and girls, grades 4 – 8
- Volleyball: girls, grades 3 – 12
The coaching staff is made up of volunteer college students and parents. Teams typically practice twice during the week and games are played in the BG/Toledo area on weekends. All athletes with varying ability are welcome. Teams are formed based on the numbers that register to play.
To be eligible, athletes must be registered parishioners at St. Aloysius, St. Thomas More, St. John XXIII, or St. Louis and enrolled in Catholic school, Religious Education program, or Catholic homeschooling curriculum. Non-parishioners who attend St. Aloysius or St. Louis grade school are also eligible. Students who attend a Catholic High School need to register in their home parish.
