Running is the fastest means of locomotion for animals with legs, including humans without a vehicle or other tool. Defined in sporting terms as a gait in which at some point all feet are off the ground at the same time.

Running is a form of aerobic exercise.


Jogging is a type of slow running that became common in the 1970s in the West. Jogging fell from favor as it is a "high-impact" exercise that places strain on the body, notably the joints of the knee. This is one of the whole ideas of the exercise, as the impact drives growth processes in the body, but many had dropped jogging to take up "low-impact" exercises such as stair climbing.

Competitive running

Perhaps the most basic of athletic contests, running races are simply contests to determine which of the competitors is able to run a certain distance fastest. Today, competitive running events make up the core of the sport of athletics.

Running competitions have probably existed for most of humanity's history, and were a key part of the ancient Greek Olympics, as well as the modern Olympic games.

Running events are usually grouped into several classes, each requiring substantially different athletic strengths and involving different tactics, training methods, and types of competitors.
