The Greiner Family OSU Cross Country Course, unveiled in 2019, is a state-of-the-art facility that serves as the home for the OSU men's and women's cross-country teams. Named after Don and Shellie Greiner and Don's father, Ken (Aug. 19, 1938-Feb. 19, 2024), the course stands out as a premier collegiate cross country competition venue. The Greiner family's significant contributions have not only funded the course but also supported counseling services for student-athletes. Construction of the course began on June 12, 2018, and was completed in July 2019. The course, which consists of just under one million square feet of Astro Bermuda grass, is carved throughout wooded areas and prairie with varying elevations. The course offers multiple loop configurations, including 10K, 8K, 6K, 5K and 2K. It has hosted prestigious events such as the 2019 Midwest Regional, the 2020 and 2022 NCAA Cross Country Championships, and the 2021 Big 12 Championships. Additionally, OSU, in partnership with the Simon Greiner Track and Field Program, hosts high school track programs and coaching clinics to promote running sports in Oklahoma City.
