BRECON, WALES - OCTOBER 16:  British Army officer cadets from the Royal Military Academy Sandhurst, march towards a checkpoint as they take part in Exercise Long Reach in the Brecon Beacons on October 16, 2013 near Brecon, Wales. The 36-hour, 50-mile march with kit, involves 200 cadets, six weeks into junior term of their year-long course, being also made to conduct a number of command tasks, testing not only their physical endurance but also their mental ability when tired and under pressure. As a result, the exercise is seen as the officer cadets first major physical and mental hurdle of the Academys demanding training programme.  (Photo by Matt Cardy/Getty Images)
