The Trinity–Mission League Challenge returns with an updated schedule and an exciting new format on Saturday, November 22, 2025, at Pauley Pavilion in Los Angeles, California. This year’s event features seven high-level basketball games showcasing premier high-school programs from Southern California’s Trinity and Mission Leagues. It’s a true challenge between two of the nation’s top leagues—and the first of its kind at the prep level. The 2025 Challenge promises an action-packed day of elite competition, with top programs battling for bragging rights and fans treated to some of the best high-school basketball in the country. The event will be split into two sessions—four games in the morning and three in the evening. The arena will be cleared between sessions to reset and provide a fresh experience for both crowds.
