Route from Prudhoe Bay, Alaska up to Quetzaltenango, Guatemala. Not even halfway! I´ll try to update this every month or so; it´s somewhat awkward.
In reality it´s around 13000 kms so far since the three straight lines are included in the graph where I had to take a ferry, bus and sailing boat; I couldn´t emit these sections from the elevation profile. Even so I think the http://www.ridewithgps.com software did well to handle all the data since it´s a long way!
Interactive version is here (where you can find the GPX if you ever want to do it!): http://ridewithgps.com/routes/2642376
