From the Promoter:
The V2B Gravel is a self-supported Gravel Adventure Bike Ride
Departing in the south of Germany near the City of Karlsruhe and following the Traverseé du Massif Vosgien in France down to Mulhouse. From there it passes through the Basel/Rhine region of Switzerland and goes back to Germany in Bad Säckingen where it follows the Black Forest bike X-ing to the north.
The V2B follows fast rolling gravel roads and some quite technical MTBtrails in between. At a distance of 1,000km the ride has an elevation gain of 17.000m and runs 85% on gravel roads, singletrack and forest paths.
