I rode this crazy event back in June, 1200km along the old inner German border. We slept in the woods and rode for 14hrs or more per day, existing on a diet of whatever we could buy in Lidl or the bakeries we occasionally passed. At the time I hated it; looking back, I've mellowed to the experience. It was epic, and by far the most extreme thing I've ever done.
We featured the race in issue 11 of Privateer, with words by Aidan Harding - he sums up the event brilliantly. There's more photos on my Flickr too.
