A collection of staff from all areas of the bank are undertaking a gruelling 24km trek over Pen Y Fan, the highest mountain in the Brecon Beacons.

This route is used as a yardstick by the SAS, whose candidates must complete the route in under 4 hours during "Hill Week". It includes over 1,000m of ascent, with steep inclines, loose and muddy paths, forested tracks and everything South Wales can throw at you in early May.
