There is spanish guy that has achieved a 1300km trip through all the north brazilian coast without assistance, while recording a documentary by himself. No support, either logistics involved. It's quite inspirational.
It's called La boya feliz (the happy boy) and the rider is Jordi Muns.
Its going to be released soon, but dont know if in english (or at least with subtitles)
A preview of the doc www.youtube.com/watch?v=qxYjiwQ1j3Ehttp://www.facebook.com/unaboyafeliz
