Colorado State, Wyoming to continue Border War series in 2026

Colorado State and Wyoming in 2026 will play for the 80th straight year on the football field.

It will be the final time as Mountain West foes with CSU heading to the Pac-12 next summer. Up until Wednesday, a two-year gap existed before the Rams and Cowboys begin an annual series playing as nonconference foes in 2028.

A gap still exists in 2027, but CSU announced it will host Wyoming on Sept. 5, 2026, to play for the Golden Boot trophy.

A 2036 game has also been added in Laramie. Although no game is scheduled for 2027, both programs are working on scheduling adjustments to potentially add it to their nonconference schedules.

“Rivalry games are important to us at Colorado State and are a part of what makes college football so special,” CSU athletic director John Weber said. “Our scheduling goal for our football program is to host seven games every season on campus in Canvas Stadium. Ram Country and Canvas Chaos make a real difference on game day and there is no better place to play than at home on campus in Fort Collins.”

The two teams have met 116 times since 1899 and every year since 1946, when CSU was still named Colorado A&M. The Border War is tied for the third-oldest college football rivalry west of the Mississippi River, behind only Cal-Stanford and Oregon-Oregon State.

The Rams lead the all-time series 60-51-5.
