Scientist have realized that running is not only beneficial to a person's health, but it can also enhance a person's memory. Running makes a person smarter. Running before taking a test not only will relax my muscles but the extra oxygen to my brain helps my mind to be sharper. Running before studying works in the same way and even running before writing an essay. If I run before sitting down to write an essay, the ideas seem to just flow without hindrance.
Runners have different reasons for running.
I enjoy long distance running not because of being able to compete with other runners but because of being able to compete against myself. Throughout the race it's as if there are two people within me, talking to me the whole time I run the race. One personality is negative and the other is positive. These two personalities either talk me out of finishing the race or into completing the race. Other runners have this experience, also.
