Encompassing mental, physical and team building exercises, event organiser the Builders Merchant Federation claims that it is the “toughest industry challenge”.

Supplier Brett Landscaping, last year’s winner, added that the event is “a great way to meet people and establish new business contacts”, as well as a great team building exercise.

Teams of four can enter the competition, with heats taking place between June 15-17 and July 13-15 in Yorkshire.
