Starting and ending in Leer, Germany, the EuroTour 2013 is a Velomobile circuit tour covering about 2500 kilometers passing through The Netherlands, Belgium, France, Switzerland and Germany over the course of three weeks. Starting date is July 21, 2013.
Quoting from the front page of the tour website: "Participants in the tour are a multinational group from several European countries, Australia, Canada and America. Registration for the tour is still open. We expect between Approximately 150 riders and support crew. At the moment, we have 136 registrants from 14 countries.
...Due to the great efficiency of velomobiles, we could cover 200 km or more per day. However, we will likely keep daily distance between 100 km to 150 km. The higher cruising speeds of the velomobile will let us visit more countries, experience a broader range of cultures and cuisine (and beer & wine!)."
