Colorado State and CU are planning to extend their football rivalry beyond the two contracts that are already in place.

The Rams and Buffs have set tentative dates to play a new four-game, home-and-home series in 2029-2030 and 2033-34, The Denver Post has learned. Where each game will be played has not been set; however, it’s likely the ’29 and ’33 games will be at Folsom Field in Boulder while the ’30 and ’34 games would be at Canvas Stadium in Fort Collins.

The current contract between CSU and CU will expire after the 2020 season. They’ve played annually since 1995 with 18 of those games in Denver, including the past nine. When the nonconference rivals play at Mile High on Aug. 30, it will be their final meeting in Denver before the contract wraps up in Fort Collins next season — the first time the Rams will have hosted since 1996.

In Feb. 2018, the two sides signed an agreement to resume the series for two games in 2023 (Boulder) and 2024 (Fort Collins). It’s unlikely they’d play between 2024 and 2029 as CU’s nonconference games in those years have already been scheduled, and CSU will play six Power 5 opponents in that same window.

This year’s Rocky Mountain Showdown will kick off at 8 p.m. Friday, Aug. 30, and will be televised on ESPN.

CU leads the all-time series 66-22-2.
