‘Grenzerfahrungen’ (Borderline Experiences) documents a self-supported cycling journey along the European Green Belt. Born and bred in Germany, Markus Stitz travelled 700km along the former Iron Curtain on a gravel bike through the federal states of Thuringia, Lower Saxony, Hesse, Bavaria and Saxony in October 2020, shortly after the 30th anniversary of the German reunification. The film launches the Iron Curtain Gravel Trail, a new bikepacking route mapped by the round the world cyclist, which is available to download for free.
