National Geographic Adventurer of the Year, Shannon Galpin founded the nonprofit Mountain2Mountain, which works with women in conflict zones. As a single-speed mountain biker continually focused on breaking gender barriers, in 2009 she became the first woman to mountain bike in Afghanistan, and now supports the Afghan Women's National Cycling Team and is producing a documentary, Afghan Cycles, about the women that dare to ride. Shannon has been featured in Outside Magazine, the New York Times, and on Dateline NBC for her work with women, street art, and cycling. She has authored two books, a photography book, Streets of Afghanistan, and her memoir, Mountain to Mountain, which comes out September 16th, 2014.
