Race Across America RAAM

I reckon this one would be good to have a go at, way cheaper as well as its unsuported, I think Mat Chester attempted it fixed one year although he might of dropped out

I've heard about that one before, there is some guy who has done it fixed a few times. If we are on about unsupported off road races the Iditarod race in Alaska although shorter needs some serious rep for the conditions.
