The idea is to go around the world. The route as of now (April 27th 2011) looks something like this..
The first leg is the only one that’s really been given much thought. That’s the trip around the US. A quick play on Google Maps having looked at the Adventure Cycling Association website got me the following map. Most of the letters actually have a reason but L, M and N were put in to get Google Maps to put the course down the coast. It’ll be interesting to see how the route looks compared to this.
