Four Kiwis on an epic journey to discover the world and themselves.

'When you're hurting and coughing on a steep incline, it's hard to see or even think of the top, but you just gotta push a pedal at a time and keep pushing.'

At Auckland Airport, a group of young Kiwis began an audacious - some would say crazy - journey, huddled together and wiping tears from their eyes.

Fourteen months later, they had cycled 23,000 kilometres, from Bali to Buckingham Palace, across more than 20 countries and adventured through some of the most exotic parts of the world. They battled extreme heat, sub-zero temperatures, culture shock and loneliness as they pushed their bodies to their limits. They overcame injury, illness, heartbreak, and, above all, their own fears and self-doubt.

It was the time of their lives.
