From suffering the pains of having giardia for two weeks to experiencing the glory of the Himalayas in person, four Kiwi men have seen it all.
The group is travelling from Bali to London by bicycle, raising tens of thousands of dollars for the Leukaemia and Blood Cancer Foundation of New Zealand in the process.
The men, all in their 20s, have been cycling for more than a year, after setting off in Bali, Indonesia on April 1 last year, but their epic journey is no joke - already they have raised more than $15,000 and still have more than a month to go.
Brothers Freddie and Arthur Gillies and their friends Sean Wakely and Timmy Chen were aiming to raise $1 for every kilometre ridden.
In late March they hit the 15,000km mark and will push on until they reach London on July 28 when the trip will end.
"In September 2016 our Uncle John passed following a long battle with cancer. His final conversation with us was about his travels through Afghanistan and the Khyber Pass.
"He told us 'in life you have your shit days and your good days. It's the shit days that build resilience'."
Chen said that after the trip was finished the men wanted to share their story and get the word out.
