Biking the Danube - For my Masters Degree Research!

I am writing my Masters thesis on the practice of cycling touring. I will be riding between Passau and Vienna on weekends throughout August and the first half of September. I would love some people to join me for rides during long weekends (Thursday-Tuesday) I am flexible with your schedule. In addition to being riding buddies, I will also interview you for 20-60 mins and ask some questions along our route. However, first and foremost I just want to have a good time and meet some new riders :) I am happy to ride any length distance per day up to about 100 KM
