According to Wikipedia, jogging is a form of trotting or running at a slow or leisurely pace. The main intention is to increase fitness with less stress than actually running, instead of competition.
The definition of jogging as compared with running is not standard. Dr. George Sheehan, a running expert, is quoted to have said "the difference between a jogger and a runner is an entry blank". Others are usually more specific, defining jogging as running slower than 6mph (10 minute per mile pace, 10 km/h, 6 min/km). In the United States, jogging was also called "roadwork" when athletes in training, such as boxers, customarily ran several miles each day as part of their conditioning.
Jogging is a "high-impact" exercise that places strain on the body, notably the joints of the knee. As a result, some people choose to take up "lower-impact" exercises such as stair climbing, swimming, aquajogging, cycling and walking instead of jogging.
Jogging is often used by serious runners as a means of active recovery during interval training. The runner who may just have completed a fast 400 metre repetition at a sub-5-minute mile pace, may drop to an 8-minute mile pace for a recovery lap.
Like other types of aerobic exercise, jogging is an excellent means of improving cardiovascular health, bone density and physical fitness.
