Watch Harrington and Ballinger Climb Cho Oyu in 14 Days

Americans Adrian Ballinger and Emily Harrington climbe Cho Oyu in 14 days last fall from California to California. Cho Oyu is the sixth tallest mountain in the world at 8,201 metres and is in Tibet.

The two strong climbers trained at home before travelling to the Himalayas. The two used supplementary oxygen from camp two to the summit, nine days after leaving America, and then skied back to base camp.

Most climbers spend a few months in the area to acclimatize, but Harrington and Ballinger used hypoxic tents at home. They mention this technique prepared their blood to handle the fast 18-hour push.
