Northfield High School offers a robust athletics program and is a member of the Colorado High School Athletics Association. Northfield High School has a full-size gym, an artificial turf multi-purpose field, baseball and softball diamonds, tennis courts, a weight room, and an aerobics room. Phase 2 construction is designed to provide additional weight and training rooms, additional locker rooms, plus the remaining tennis courts in the design plan. The list below includes all sports teams offered. Additional non-CHSAA sports may be offered as club teams per student demand. Northfield High School Athletics also offers Special Olympics Unified Sports teams. Additionally, Northfield High School participates in joint teams with the Far Northeast Warriors for sports in which we do not field our own teams. In such cases, students are still required to meet Northfield High School‘s eligibility criteria in order to play.
