It's 60-year-old Fiona's time to shine. She's a fitness instructor, runner, horse rider and now a champion powerlifter, and she tests the group's mettle with her challenging hike to beautiful Rubha Hunish, the northernmost point of the island.After 30 years on Skye, Fiona is fiercely proud of her adopted north Skye home. Her 8.5km walk along the headland is a birdwatcher's paradise, with epic cliff top views stretching miles out to sea.But they need to navigate the blustery coastline and a knee-trembling scramble down a steep cliff along the way. Can Fiona power through to the finish to claim the prize?
