Don Berens will present a lecture titled Corsica's GR20 Trail: The Toughest Long Distance at the Adirondack Mountain Club, Genesee Valley Chapter Meeting in the Eisenhart Auditorium of the Rochester Museum and Science Center.

Europe has dozens of long-distance hiking trails, each called a Grande Randonee (French), Gran Recorrido (Spanish), Grote Routepaden (Dutch), or simply "GR." The spectacular 118-mile GR20 traverses Corsica — the French Mediterranean island known as "The Isle of Beauty" and "The Granite Isle", 2/3 of which is comprised of mountains featuring 121 summits over 6600'. To do the GR20 means taking on its 41,000 feet of ascent, and another 41,000 feet of descent.
