Mount Everest Climb Record
Hans Kammerlander is an Italian mountaineer, who at age 61, managed to set the record for the fastest time climbing Mount Everest. Somehow, he climbed up the mountain in just 16 hours and 45 minutes. While there are trails and proper guides to help one scale the mountain faster these days, you still have to climb 8,848 meters or a little over 29,028 feet. That is difficult on the body, especially when it comes to breathing. This is why many might carry oxygen to help them climb up faster.
Yet Kammerlander never used any supplemental oxygen climbing up Everest or coming down. That makes his climb one of the greatest athletic accomplishments one could hope to achieve. Of course, he has also climbed most of the 8000-meter peaks on Earth now too. That meant his body had been acclimated to the mountain environment. To do this, Kammerlander had to build up his cardio but also his lungs. The air is harder to breathe as you reach higher altitudes, so most treks up Everest take several days so that people can adjust their bodies. Therefore, to do it in less than a day, you need remarkable health.
