Assault courseHitting the wall: It must have been just like time in the office for these brave souls from the Guildford branch of Clyde & Co, who last month swapped their suits for natty corporate leisurewear to clamber across Sandhurst's Royal Military Academy assault course.

The lawyers encountered 'formidable walls, dark tunnels, scramble nets, ropes and plenty of freezing, muddy water', the firm said, 'a challenge that leaves many begging for mercy'.

A more accurate metaphor for legal practice you are unlikely to find.

The lawyers raised more than 3,000 for the Anthony Nolan Bone Marrow Trust.
