The town of Richmond maintains an agreement with the district that gives its high school students an option to attend MMRHS. The school's athletic teams are called the Spartans, and their colors are maroon and white. Sports are offered at the junior varsity and varsity level for the students to participate in, including football, soccer, baseball and softball, swimming, track and field, tennis, fencing, and cross country running. The Spartans enjoy rivalries with, among other schools, the Lee High School Wildcats, in Lee, Massachusetts and the Lenox Memorial High School Millionaires in Lenox, Massachusetts.
