The I-35 Orange vs. Maroon Rivalry series is the name given to the athletic competitions between the Roadrunners and the Texas State Bobcats. The name is derived from the Interstate highway that essentially links the two schools who are in relatively close proximity to each other. In the beginning of the rivalry, a trophy was awarded to the winner of the men's basketball game. It has grown, however, to include all common sports the two schools compete with each other in throughout the academic year. A point system is used to crown a winner after the last competition between the schools in that year. The trophy is then inscribed with the annual winners and the winning institution retains the trophy for one year until the next winner is crowned.
