The Endurance march in the Brecon Beacons.

It follows the very same route marched by UKSF selection personnel on their final stage of Test Week, on the aptitude phase of Selection. The Endurance march is by far the toughest challenge faced by UKSF candidates on this phase of the selection course. Soldiers are carrying in excess of 55lb (Not including food, water & rifle) and have to navigate from checkpoint to checkpoint individually.

Similarly to UKSF selection each registrant on this event will have to cover the 64km (40mile) route visiting various checkpoints along the route.
