"In no organized sport do the participants have to endure days of struggle just to get to the starting line of their event. The option to drop out of a race that is going badly does not exist for a climber halfway up a big route, and may entail more risk than pushing on. A team of volunteers will not be waiting with warm blankets and hot food at the next bivy ledge. When you reach the summit, having overcome the challenges that inspired you for months or years, you are not at the finish line. The race is not over. You can't relax and let your guard down like a normal athlete."
