At the age of 24, Alastair Humphreys set off to try to cycle round the world. By the time he arrived back home, four years later, he had ridden 46,000 miles across five continents on a budget of just £7,000.

From frozen Siberia tundra to the jungles of central Africa, Alastair recounts his extraordinary adventures in two parts - Moods of Future Joys and Thunder & Sunshine - brought together in audiobook for the first time.

Moods of Future Joys is the story of the first stage of this epic journey. Struggling with the enormity of the challenge he had set himself, Alastair recounts the hardships of the expedition with great honesty. His ride through Europe, a turbulent Middle East and down Africa is buoyed by the kindness of strangers and the thrill of the freedom of the open road.

In Thunder & Sunshine, Alastair continues his journey from South Africa back to Yorkshire, via the whole of the Americas, South to North, Siberia, Japan, and back through China, Central Asia and Europe.

A tale of physical and mental endurance, of taking on wilderness, loneliness and danger in a time before mobile phones and GPS - this is a refreshingly original account from one of today's great adventurers.
