73-year-old free-spirited retired psychiatric nurse Edwin leads the other walkers on a historic hike. He discovered a taste for adventure later in life, so he's got a few surprises planned to keep his fellow walkers on their toes - kicking off with a nerve-wracking abseil to give them a bird's-eye view of his starting point at Brimham Rocks.
As well as jaw-dropping geology, Edwin is hoping his fact-filled day following in the footsteps of monks and ending at the spectacular Fountains Abbey will win over his fellow walkers. But will his 9km hike prove a step too far for some?
