5 Athletes Run World's Highest Marathon at 22,614 Feet

Five runners just completed a marathon on top of Earth's highest active volcano, battling 62 mph winds and minus 22-degree temperatures at nearly 23,000 feet above sea level.

The grueling 16 to 18-hour race down Chile's Ojos del Salado volcano shattered the previous high-altitude marathon record by over 3,000 feet.
