Summer 2018. The 1500 km epic biv flight of Damien LACAZE and Antoine GIRARD in the core of Himalaya and Karakorum mountains. This journey is actually a prelude and acclimatization to climb the Spantik (7027m) from the nearest city in two days, thanks to paragliding. Is it really achievable? What are the limits of such an ascent? Can we really come back unscathed?
