Ultimate Hell Week - The Professionals

Models and influencers, sports stars and soaps stars, singers and comedians all think they have what it takes to pass this year's special Hell Week course. Each of them has excelled in their chosen field but now their reputations are on the line, as they go way beyond their comfort zone, to face the biggest test of their lives.

The next phase of the course sees the recruits pushed to their absolute physical limits, with back-to-back events including boarding a large ship as it sails through Cork Harbour.

It's fight or flight time as the remaining 14 recruits travel to Mizen Head for the next terrifying Hell Week event, the dead drop.

The challenge continues with a boat race across the busy shipping lanes of Cork harbour, before the recruits are paired off to box one another in two one-minute bouts.

The recruits start the hardest test on the Hell Week course - Foreman Aftman - a timed mountain march with over 50kg of kit of their backs.

Ultimate Hell Week has reached its final phase. Of the 18 recruits who started, only four candidates now remain. The courses culminates in one final event. Who will crack? Will any of them make it to the end?
