Each region will advance one team to the state tournament which will begin on Nov. 9 at the Denver Coliseum.

Class 1A

The 1A regionals feature two-team parings, the only classification to do so. That makes things real simple for these teams. A win advances them to the Denver Coliseum and a loss sends them home. Three-time defending champion Merino is the top seed in 1A.

Stratton, McClave, Simla, Otis, Idalia, Briggsdale, Dove Creek, Haxtun, La Veta, Cheraw and Weldon Valley are the other 1A region hosts.
