Sign outside of a building in Boonsboro, Va., welcoming the participants of the JFK 50-Mile Ultra marathon, Nov 19. The race was first held in the spring of 1963, and although open to the public, the JFK 50 Mile is in spirit a military race. The initial inspiration behind the event came from then President John F. Kennedy challenging his military officers to meet the requirements that Teddy Roosevelt had set for his own military officers at the dawn of the 20th Century. That Roosevelt requirement was for all military officers to be able to cover 50 miles on foot in 20 hours to maintain their commissions. The U.S. Army Special Forces Command (Airborne) sent a team up to participate in the JFK 50-Miler and to honor its own legacy with the fallen president.
