Fifty-one-year-old fitness and body coach Zara takes the group on a hike across Llandudno's Great Orme. They climb the hillside to reach the summit, past the historic Great Orme tramway. From there, it's a quick descent down to the west shore, taking in a gorgeous 360 degrees of the north Wales coastline.As well as jaw-dropping views, Zara hopes her fitness-filled Great Orme walk - topped off with a spot of paddleboarding for good measure - will be a sure-fire slam dunk with the rest of the group. But could it be one challenge too far for the others?
