Ray Zahab has run in some of the most extreme places and conditions in the world. From the Sahara Desert to Death Valley and most of the major deserts in the world, he's crossed them on foot in the hottest parts of the year. On the other extreme, he's done multiple Arctic treks, including a world record to the South Pole.

He uses running and adventure as a way to instruct and inspire students around the world who follow his adventures and interact in real time with him. And he founded Impossible to Possible, an organization that takes students out of the classroom to experience their own adventure challenges.
