"The crux of it is, if this wasn't a selfish, boy's-own adventure, I don't think it would have worked," the 34-year-old former British army captain told the Associated Press. "I am simply doing it because no one has done it before."
The trek cost about $100,000 and was mainly paid for by donations.
Stafford and a buddy came up with the idea over a beer back in England, but about three months into the epic walk his buddy bailed out of the expedition.
Instead he met up with Gadiel "Cho" Sanchez Rivera, a 31-year-old Peruvian forestry worker, who finished the trek with him at the mouth of the Amazon
