The intensity level of endurance sports is rising. It’s the natural  progression of these sports that allows todays athletes to achieve feats  unthought of fifty years ago. In ultramarathons, people are now racing  for 100 miles. That’s a big deal. But I think this phenomenon is even  more obvious in climbing. The alpinists of today move lightning fast  over terrain that once stymied the best climbers in the world. To do so,  they give up certain elements of protection in favor of speed, meaning  mistakes have more consequences. Among the best, this is a reasonable  trade because the athletes are extraordinarily confident and capable.  The problem is that the 99% who aren’t the best see these  accomplishments and want to achieve similar feats themselves. They  forget about the progression.
