Aaron and Gareth call their expedition Brazil 9000 and it will begin at Monte Caburaí, a 1465 meter (4806 ft) mountain on the border of Brazil and Guyana. From there, they'll travel south by canoe through the Amazon, then by foot across the dense Caatinga forests and along thousands of miles of coastline, before finishing the final stage of the journey by bike, eventually ending in Chuí, a small town on the border with Uruguay.
Once they get under way in a couple of months, we'll be able to follow Aaron and Gareth through updates to their Facebook page and Twitter feed. The boys promise to keep us well informed of their progress and share all kinds of unique aspects of Brazilian history and culture. They estimate that it will take roughly 15 months to finish their human-powered journey across Brazil.
This isn't Aaron and Gareth's first visit to the Amazon. The duo made a great short film of their previous expedition to the Amazon, which you can find below. It's a fantastic look at an amazing part of the world and if this is an indication of what we can expect from Brazil 9000, we're all in for a treat.
