Skier and all-around mountain sport expert Greg Hill had a simple but difficult plan: summit 100 peaks without burning fossil fuel to do it. No cars, no planes, no helicopters, no snowmobiles. He could walk, ride a bike, drive an electric car—but no direct gas burning. This short film takes you along on his journey, one that extends far beyond just those 100 miles. Hill’s life changed in the process. At first, it was a challenge, then, a habit, then, just a sensible way to live.
