Mongolia to Sweden on quadbikes, 12000 km
If you're interested, here's a link to a trailer from a trip me and a friend of mine did 6 months ago. There will be 4 episodes in total. We traveled with ATV's and started the journey in Mongolia, then Russia, Kazakhstan, back to Russia, Ukraine, Poland and finally finished in Sweden 12000 km later.
We recorded most parts of the trip with handcameras, for our own interest. Apparently we had enough photage to make these small episodes (produced by a production company). The first episode will be released the 25th of january.
