Wales, United Kingdom—Exercise Cambrian Patrol: Is this the world’s toughest military exercise?

Forty-eight hours. Over 40 miles across the arduous Brecon Beacons. Weather conditions: awful. Personal loads in the excess of 80 pounds. Who will win?

Did I mention that Cambrian Patrol is an unofficial race?

The annual exercise is organised by the 160th Infantry Brigade of the British army. Every year, the Welsh-based brigade is responsible for creating an event that contains the most difficult tasks that an infantry patrol might encounter. Patrols from units across the British military are welcomed, as well as units from foreign countries.
