Title: I am Colin O'Brady - pro endurance athlete at Everest Base Camp - AMA!
My short bio: Hi Reddit! This is Colin O'Brady, answering questions from Everest Base Camp at 17,600ft above sea level. In the last four months I have skied the last degree to the North and South Pole and climbed Mt. Vinson, Aconcagua, Kilimanjaro, Carstensz Pyramid, and Mt. Elbrus (5 of the 7 summits) all in an attempt to become the fastest person to complete the Explorers Grand Slam. Only Everest and Denali remain to complete. I'm also raising $1M for the Alliance for a Healthier Generation to promote the importance of healthy, active kids.

Edit: Thanks for all of your amazing questions. I'm headed up the Khumbu Icefall in the morning and I need to get some sleep. Follow @beyond_72 for daily updates on snapchat and Instagram
