Yes you read the title correctly, Dimitri Keiffer is attempting to Circumnavigate the globe by purely human power. Dimitri began his adventure in February of 2005 and is currently in Vernhiy Paren, Magadanskaya Oblast. His goal is not only to circumnavigate the world but also to connect with the peoples and societies he crosses paths with.
Sounds like a very exciting and educational long walk. You can follow along with his trek at his blog Nexus explorer.
