Teams were given their final times as they entered a mud pool at the end of the Diversity Day mud run September 20, 2015 at Al Udeid Air Base, Qatar. The mud run challenged 106 runners with a two mile course that contained several obstacles from low crawling, T-wall climb, barrier hurdles, and Ôdeep freezeÕ cold mud pool. The event was held to help spread the word of Diversity Day, an initiative started by the Department of Defense for events held throughout the year. (U.S. Air Force photo/ Staff Sgt. Alexandre Montes)
