If you think you're hardcore because you survived our recent snap of intensely cold weather, wait until you hear the story of Hilaree O'Neill. The veteran mountaineer climbed both Everest and Lhotse in a 24-hour period (seriously), and in this talk she'll be sharing the story of her ascent of Burma's Hkakabo Razi. Filled with tales of hypothermia, gale force winds and perilous gendarmes, O'Neill will surely keep you on the edge of your seat.
