Risks of Running
The risk of running is primarily to the joints because you hit the ground with two to three times your body weight. You should be cautious if:
For men and women considering more ambitious training, research suggests that running more than 40 miles per week is a risk factor for injury in both genders, particularly in the knee. The risk seems to be higher for men, perhaps because men are heavier.
To reduce ground-impact forces, avoid concrete and run instead on soft, flat ground like a cinder track, boardwalk, grass (watch for holes), or a dirt path. Treadmills are softer than the road, and so if you have an opportunity to use one, you might want to take advantage of that.
No one has a crystal ball when it comes to predicting who will or will not develop knee problems, so again, practice common sense and listen to your body. Don't do it if it hurts, never run through pain, and see your doctor when you do have pain that lasts for more than a few days.

Here are some suggestions for proper form:
