The community of Flagstaff, Arizona (at an elevation of 7000 ft / 2100m) began hosting elite athletes who were preparing for the 1968 Olympics in Mexico City and who were seeking an altitude environment in which to prepare for high profile national and international competitions. As such activity and interest in altitude training continued to grow over the next few decades, the Center for High Altitude Training at Northern Arizona University (NAU) opened in 1995 on the NAU campus  in order for the community to better serve this athlete population.

From 1995 to 2008, the Center for High Altitude Training established itself as one of the preeminent organizations to coordinate altitude-based training camps, garnering a worldwide reputation for excellence on both the service and facility front. In 2009, the Center closed (largely due to the university’s budget reduction) and HYPO2, made up of experienced sport management staff who’d worked for the Center, was founded to pick up where NAU had left off.

Since 2009, HYPO2 has continued to expand on the offerings of the NAU-based program, refining the production and management of altitude training camps in Flagstaff, serving more and more elite athletes from more and more countries, and keeping Flagstaff front and center as the best possible place on the planet for altitude training.
