Tough Rides: China, Episode 4: Towards Tibet

In 2010, when Canadian brothers Colin Pyle and Ryan Pyle set out from Shanghai on a motorcycle journey that had never previously been attempted, they thought they had some idea of what lay ahead of them. It was a misconception that became evident by the end of Day 1. But, despite the many challenges they faced, 65 days and 12,000 miles later they'd succeeded in circumnavigating China.

In this fourth episode from Ryan Pyle Productions, after Ryan has recovered from the worst motorcycle fall he's ever had, the Pyle brothers aim for Tibet on the G219 highway, passing mountains and lakes including one of the most holy places in Asia, Lake Manasarovar. Their ultimate goal is Mount Everest Base Camp, but it's not going to come easy.
