SAS Endurance Event Overview

The SAS Endurance event is a long-distance march held in the United Kingdom, specifically starting from the Talybont Reservoir Layby in Talybont-on-Usk. The route covers a course through the highest peaks in South Wales, emulating the final stage of the aptitude phase used in UKSF selection. Participants traverse terrain traditionally used for military selection testing.

Participants can choose between two primary distances with different participation modes:

  • 64 km (Full Distance): Available as a self-navigated individual entry or a DS-led group entry.
  • 32 km (Half Distance): Available as a self-navigated individual entry or a DS-led group entry, finishing at Cray Reservoir.

The event includes specific safety and navigation requirements. For the self-navigated categories, participants must demonstrate navigation proficiency through prior experience or by attending designated training sessions. Those opting for the Guided (DS Led) versions of the 64 km or 32 km routes are led in a group by staff, and individual navigation is not required.

The course features marshaled areas and water at designated checkpoints. Medical teams and a Mountain Safety Detachment are present across the route. Staff maintain the authority to stop any participant at checkpoints if they are deemed unfit to continue. Several cut-off times are implemented at specific checkpoints, which are designated by the staff based on weather and ground conditions on the day. The event is scheduled to begin late Friday night or at the start of Saturday morning. Visit the organization's website for the most recent information.
