Grassroots 365
United States - Basketball
Grassroots 365 (G365) is a United States youth basketball tournament, circuit, rankings and media operator launched by Open Gym Premier in Southern California in 2016. It primarily serves boys’ club teams from second through eighth grade, while selected events also offer high-school boys’ and girls’ divisions. G365 organises regional and national tournaments, including The Championship, and states that its programme has delivered more than 1,200 events for over 25,000 club teams and 115,000 athletes. The Circuit, presented with Open Gym Premier, is a West Coast tournament series with seasonal standings, qualifiers and Cup events. The organisation publishes rankings, player and team certification guidance, event recaps and schedules. Its current calendar lists 2026–27 events in California, Arizona, Washington, Texas, Nevada and other regions. This record concerns the commercial tournament and circuit operator, not USA Basketball, Open Gym Premier itself, a club or a single tournament.
