Instruction:
Why do people like to run very long distances like marathons?

Response:
As with all endurance sports, long distance running can pose an enjoyable challenge for some people. Some athletes are known to like running for its health benefits, its feeling of calm or meditative relaxation, or companionship with other runners. Whether running for fun or in a competitive race event, the feeling of accomplishment that comes from tackling a long distance by foot brings joy to many people. It may not be the best activity for all people though, and some may find activities such as bike riding or water-sports a more enjoyable way to achieve the same feeling.
