Extreme Dreams The Ultimate Challenge - Ricochet - BBC2

In this new series, Ben Fogle is on an epic South American adventure from the Equator to the Tropic of Capricorn, supported by teams of deserving heroes who will help him take on the world's toughest environments.

Ben's journey begins in Ecuador where he leads his team through the Avenue of Volcanoes to summit Mount Chimborazo - the closest point to the sun on Earth. Ben and his team of heroes launch their summit attempt in darkness on the final day but with icy blizzard conditions battering the team and the constant threat of debilitating altitude sickness, it's one of Ben's most challenging expeditions.
