Not only is [a half marathon] a good test for the marathon, it is also good for those who feel they were just getting going in a 10K and are physically and mentally primed to go further. A half marathon is a good test of your endurance, without the physical punishment of going the full 26.2 miles.

In addition to the well-known benefits of health and well-being derived from exercise, there are other unique advantages to being a runner. You are more attuned to not only your body but also the world around you. The outdoor life you lead as a runner gives you a special relationship with your surroundings: nature, the climate, the seasons. As you depend on these things to accommodate your activity, you grow to understand and appreciate them.
