As things get under way, Ewan and Charley undergo fitness and survival training to prepare for their 15,000-mile adventure.

After visiting Ewan's family in Scotland, he and Charley attempt to stay on a strict time schedule as they push through London and France.

Ewan and Charley battle traffic in Rome. Tensions run high on the ferry ride from Sicily to Tunisia about Charley's dangerous bike stunts.

Riding through Egypt, the guys doubt whether they'll make it to Aswan in time for the ferry—and will be delayed for a week if they miss it.

The guys are starting to embrace Africa, but fatigue begins to creep in as the long riding days—and Ethiopia’s heat—take a toll.

The soft sand in Kenya makes it difficult to keep the bikes upright. When the terrain finally changes, it causes even more problems.
