If you’re a pack-a-day smoker who isn’t particularly athletic, perhaps one day you’ll kick the habit and become an elite, long-distance runner. Sound impossible? Ray Zahab will tell you it’s not.  The endurance athlete is known for pushing himself to the limit in some of the most extreme conditions on Earth. In 2009, he crossed Antarctica on foot and snowshoes, setting the world speed record. He has also run across the Sahara Desert and, last summer, he ran 2000 miles across the Gobi desert in Mongolia. If that weren’t enough, Ray is the founder of the Impossible2Possible Foundation, which takes young people on expedition treks around the world. CTV’s Kevin Newman had a chat with Ray about his current trek in the Arctic, which you can watch here.
