It's the final week of Tom's global adventure, and he and Sophie are ending their whistle-stop world tour in Morocco, where they will endeavour to climb 600ft up a cliff and rappel into a gorge.They shop for souvenirs in the bustling markets of Marrakech and get treated to a Hammam body scrub, but a meal of animal brains and eyes are also on the itinerary…if they can stomach it. They travel through Morocco's epic landscape on the Tizi N'Tichka pass, and brave a night in the legendary Sahara desert where Tom faces humps and more than a few bumps with a mischievous camel.Within touching distance of home their final challenge is climbing the Todra Gorge - but its rock hard, and even Olympian Tom is tested to the limit.
