Foxy's Fearless 48 Hours With... | Preview (Channel 4)

American actor and comedian Rob Delaney joins Jason Fox (AKA Foxy from SAS: Who Dares Wins) for 48 hours in rural north Wales that he'll never forget.

Over two days, Rob faces three petrifying challenges, ranging from the simply gut-wrenching to the downright terrifying, each one designed by Foxy to push Rob's boundaries and build resilience.

First stop on their adventure is a 40-metre-high abandoned viaduct which Foxy wants Rob to jump off. With the challenge set, it's off to the overnight accommodation to start the mental preparation for what's coming next.

The next morning, training day begins with some tombstoning - to get Rob used to the idea of jumping from a considerable height by taking on a 30-foot cliff jump into a flooded quarry called the pool of death.

If Rob is successful, Foxy will set him the task of crossing a 300-foot-long highline spanning a 250-foot drop, where halfway across they drop into the abyss. If Rob can survive these two challenges, he should be mentally prepared for the viaduct jump.

With breath-taking visuals, nerve-jangling challenges, and confessional conversations, Foxy's Fearless 48 Hours... shows how every one of us is capable of doing something extraordinary.

Foxy's Fearless 48 Hours... begins Sunday 26th September at 10pm on Channel 4.
