Going the distance
Chief Master Sgt. Geoff Weimer, 5th Bomb Wing command chief, leads a group of Airmen on the 50th mile of a 52 mile run at Minot Air Force Base, N.D., July 24, 2015. To prepare for the event, Weimer made distance adjustments to his regular running routine and factored in fatigue and physical stress. (U.S. Air Force photo/Senior Airman Stephanie Morris)
