Foxy's Fearless 48 Hours with Rob Delaney

The first in a series in which Jason Fox sets celebrities daring challenges designed to push boundaries and build resilience. First up is actor and comedian Rob Delaney, who is challenged to jump off a 40-metre-high abandoned viaduct, and diving from a cliff into a flooded quarry. The final test is crossing a 300-foot long highline spanning a 250-foot-drop.
