After an unexpected cold shower with a garden hose, we headed back to base camp to cross the finish line, with dirt, sweat and weighted vests still in tow. Some ran, some stumbled and some crawled there, but we all made it and the sense of accomplishment was pretty great.

That struggle to the finish was perhaps the most enlightening part of the experience: to feel the camaraderie between the team members as we endured together, in the dirt and mud;  it became easier to see why so many are loyal to the military service.

If you want to test your own mettle you can do a similar challenge at Cataract Scout Park, but heed just one piece of advice: come prepared.

Battleship is released on Blu-ray & DVD August 9
