U.S. Air Force Staff Sgt. Brendan Brustad and 1st Lt. James Laughridge, both from the 509th Medical Support Squadron, run during the early hours of the day at Whiteman Air Force Base, Mo., May 19, 2015. The Joplin Memorial Run is an annual event where participants can register to run a half-marathon or a 5K. Brustad registered for the run but rather than running the distance, he ran 161 miles over the course of six days, all on Whiteman Air Force Base.
