Everest and Lhotse Without O2 in Single Push

"Forty-eight hours after summiting Lhotse, Piotr Krzyzowski of Poland has reached the top of Everest. He did both without oxygen or sherpa support and without descending lower than Camp 4.

At the time of writing this story, Krzyzowski was still on his way back to Camp 4. We will update as soon as we have news.

Krzyzowski has always climbed toting his own tent and supplies. Last weekend, he also helped rescue a Macedonian climber on his way to Camp 4."
