At 5:20 a.m. on Monday, four hours before the Boston Marathon's elite runners took off, a group of 15 active-duty soldiers from the Massachusetts National Guard gathered at the starting line in Hopkinson. Each soldier was in full combat uniform and carried a "ruck," a military backpack weighing about 40 pounds. The rucks were filled with Camelbacks of water, extra uniforms, Gatorade, changes of socksand first-aid and trauma kits. It was all just supposed to be symbolic.
"Forced marches" or "humps" are a regular part of military training, brisk walking over tough terrain while carrying gear that could help a soldier survive if stranded alone. These soldiers, participating in "Tough Ruck 2013," were doing the 26 miles of the Boston Marathon to honor comrades killed in Iraq and Afghanistan, or lost to suicide and PTSD-related accidents after coming home.
It took about eight hours for all of the soldiers to cross the finish line, some cruising nearly at a 13-minute mile, others coming in at a little slower pace. They were gathered near the medical tent behind the finish line, waiting for the elite runners to come in. That was the contingency plan in case anything went wrongmeet by the medical tent.
"You never think you're gonna need it, but you always have to have a contingency plan," says Lieutenant Stephen Fiola of the 1060th Transportation Company, who worked with the Military Friends Foundation to organize the march. Two soldiers stationed in Afghanistan also participated in the ruck from afar, according to Fiola, marching in circles around their base for 26 miles in remembrance of fallen comrades.
