Running is a method of terrestrial locomotion by which humans and other animals move rapidly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions).[1] This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.[2] A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity.[3] The term "running" can refer to a variety of speeds ranging from jogging to sprinting.

Running in humans is associated with improved health and life expectancy.[4]

It is hypothesized that the ancestors of humankind developed the ability to run for long distances about 2.6 million years ago, probably to hunt animals.[5][6] Competitive running grew out of religious festivals in various areas. Records of competitive racing date back to the Tailteann Games in Ireland between 632 BCE and 1171 BCE,[7][8][9] while the first recorded Olympic Games took place in 776 BCE. Running has been described as the world's most accessible sport.[10]

It is thought that human running evolved at least four and a half million years ago out of the ability of the ape-like Australopithecus, an early ancestor of humans, to walk upright on two legs.[11]

Early humans most likely developed into endurance runners from the practice of persistence hunting of animals, the activity of following and chasing until a prey is too exhausted to flee, succumbing to "chase myopathy" (Sears 2001), and that human features such as the nuchal ligament, abundant sweat glands, the Achilles tendons, big knee joints and muscular glutei maximi, were changes caused by this type of activity (Bramble & Lieberman 2004, et al.).[12][13][14] The theory as first proposed used comparative physiological evidence and the natural habits of animals when running, indicating the likelihood of this activity as a successful hunting method. Further evidence from observation of modern-day hunting practices also indicated this likelihood (Carrier et al. 1984). [14][15] According to Sears (p. 12) scientific investigation (Walker & Leakey 1993) of the Nariokotome skeleton provided further evidence for the Carrier theory.[16]

Competitive running grew out of religious festivals in various areas such as Greece, Egypt, Asia, and the East African Rift in Africa. The Tailteann Games, an Irish sporting festival in honor of the goddess Tailtiu, dates back to 1829 BCE and is one of the earliest records of competitive running.[17] The origins of the Olympics and Marathon running are shrouded by myth and legend, though the first recorded games took place in 776 BCE.[18] Running in Ancient Greece can be traced back to these games of 776 BCE.

...I suspect that the sun, moon, earth, stars, and heaven, which are still the gods of many barbarians, were the only gods known to the aboriginal Hellenes. Seeing that they were always moving and running, from their running nature they were called gods or runners (Thus, Theontas)...

Running gait can be divided into two phases regarding the lower extremity: stance and swing.[20][21][22][23] These can be further divided into absorption, propulsion, initial swing, and terminal swing. Due to the continuous nature of running gait, no certain point is assumed to be the beginning. However, for simplicity, it will be assumed that absorption and footstrike mark the beginning of the running cycle in a body already in motion.


Footstrike occurs when a plantar portion of the foot makes initial contact with the ground. Common footstrike types include forefoot, midfoot, and heel strike types.[24][25][26] These are characterized by initial contact of the ball of the foot, ball and heel of the foot simultaneously and heel of the foot respectively. During this time, the hip joint is undergoing extension from being in maximal flexion from the previous swing phase. For proper force absorption, the knee joint should be flexed upon the footstrike, and the ankle should be slightly in front of the body.[27] Footstrike begins the absorption phase as forces from initial contact are attenuated throughout the lower extremity. Absorption of forces continues as the body moves from footstrike to midstance due to vertical propulsion from the toe-off during a previous gait cycle.


Midstance is when the lower extremity limb of focus is in knee flexion directly underneath the trunk, pelvis, and hips. At this point, propulsion begins to occur as the hips undergo hip extension, the knee joint undergoes extension, and the ankle undergoes plantar flexion. Propulsion continues until the leg is extended behind the body and toe-off occurs. This involves a maximal hip extension, knee extension, and plantar flexion for the subject, resulting in the body being pushed forward from this motion, and the ankle/foot leaves the ground as the initial swing begins.

Propulsion phase

Recent research, especially in the footstrike debate, has primarily focused on identifying and preventing injuries during the absorption phases of running. The propulsion phase, which occurs from midstance to toe-off, is crucial for understanding how the body moves forward.[21][22][28]

In a full stride length model, elements of both the terminal swing and footstrike contribute to propulsion.[23][29] The setup for propulsion begins at the end of the terminal swing when the hip joint flexes, allowing the hip extensors to generate force as they accelerate through the maximal range of motion.

As the hip extensors transition from inhibitory to primary muscle movers, the lower extremity moves back towards the ground, aided by the stretch reflex and gravity.[23] The footstrike and absorption phases follow, leading to two possible outcomes.

With a heel strike, this phase may be just a continuation of momentum from the stretch reflex, gravity, and light hip extension, offering little force absorption through the ankle joint.[28][30][31] On the other hand, a mid/forefoot strike helps in shock absorption, supporting plantar flexion from midstance to toe-off.[31][32]

Actual propulsion begins as the lower extremity enters midstance.[28] The hip extensors continue contracting, assisted by gravity and the stretch reflex from maximal hip flexion during the terminal swing. Hip extension pulls the ground underneath the body, propelling the runner forward.

During midstance, the knee should be slightly flexed due to elastic loading from the absorption and footstrike phases, preserving forward momentum.[33][34][35] The ankle joint is in dorsiflexion at this point, either elastically loaded from a mid/forefoot strike or preparing for stand-alone concentric plantar flexion.

The final propulsive movements during toe-off involve all three joints: ankle, knee, and hip.[28][30][31][32] The plantar flexors push off from the ground, returning from dorsiflexion in midstance. This can occur either by releasing the elastic load from an earlier mid/forefoot strike or through concentric contraction from a heel strike.

With a forefoot strike, the ankle and knee joints release their stored elastic energy from the footstrike/absorption phase.[33][34][35] The quadriceps group/knee extensors fully extend the knee, pushing the body off the ground. Simultaneously, the knee flexors and stretch reflex pull the knee back into flexion, initiating the initial swing phase. The hip extensors extend to the maximum, contributing to forces pulling and pushing off the ground, as well as initiating knee flexion and the initial swing phase.

Swing phase

Initial swing is the response of both stretch reflexes and concentric movements to the propulsion movements of the body. Hip flexion and knee flexion occur, beginning the return of the limb to the starting position and setting up for another foot strike. The initial swing ends at midswing when the limb is again directly underneath the trunk, pelvis, and hip with the knee joint flexed and hip flexion continuing. Terminal swing then begins as hip flexion continues to the point of activation of the stretch reflex of the hip extensors. The knee begins to extend slightly as it swings to the anterior portion of the body. The foot then makes contact with the ground with a foot strike, completing the running cycle of one side of the lower extremity. Each limb of the lower extremity works opposite to the other. When one side is in toe-off/propulsion, the other hand is in the swing/recovery phase preparing for footstrike.[20][21][22][23] Following toe-off and the beginning of the initial swing of one side, there is a flight phase where neither extremity is in contact with the ground due to the opposite side finishing terminal swing. As the footstrike of the one hand occurs, the initial swing continues. The opposing limbs meet with one in midstance and midswing, beginning the propulsion and terminal swing phases.

Upper extremity function

The upper extremity function serves mainly in providing balance in conjunction with the opposing side of the lower extremity.[21] The movement of each leg is paired with the opposite arm, which serves to counterbalance the body, particularly during the stance phase.[28] The arms move most effectively (as seen in elite athletes) with the elbow joint at approximately 90 degrees or less, the hands swinging from the hips up to mid-chest level with the opposite leg, the Humerus moving from being parallel with the trunk to approximately 45 degrees shoulder extension (never passing the trunk in flexion) and with as little movement in the transverse plane as possible.[36] The trunk also rotates in conjunction with arm swing. It mainly serves as a balance point from which the limbs are anchored. Thus trunk motion should remain mostly stable with little motion except for slight rotation, as excessive movement would contribute to transverse motion and wasted energy.

Footstrike debate

Recent research into various forms of running has focused on the differences in the potential injury risks and shock absorption capabilities between heel and mid/forefoot footstrikes. It has been shown that heel striking is generally associated with higher rates of injury and impact due to inefficient shock absorption and inefficient biomechanical compensations for these forces.[24] This is due to pressures from a heel strike traveling through bones for shock absorption rather than being absorbed by muscles. Since bones cannot disperse forces easily, the forces are transmitted to other parts of the body, including ligaments, joints, and bones in the rest of the lower extremities up to the lower back.[37] This causes the body to use abnormal compensatory motions in an attempt to avoid serious bone injuries.[38] These compensations include internal rotation of the tibia, knee, and hip joints. Excessive compensation over time has been linked to a higher risk of injuries in those joints and the muscles involved in those motions.[30] Conversely, a mid/forefoot strike has been associated with greater efficiency and lower injury risk due to the triceps surae being used as a lever system to absorb forces with the muscles eccentrically rather than through the bone.[24] Landing with a mid/forefoot strike has also been shown to properly attenuate shock and allow the triceps surae to aid in propulsion via reflexive plantarflexion after stretching to absorb ground contact forces.[29][39] Thus a mid/forefoot strike may aid in propulsion. However, even among elite athletes, there are variations in self-selected footstrike types.[40] This is especially true in longer distance events, where there is a prevalence of heel strikers.[41] There does tend however to be a greater percentage of mid/forefoot striking runners in the elite fields, particularly in the faster racers and the winning individuals or groups.[36] While one could attribute the faster speeds of elite runners compared to recreational runners with similar footstrikes to physiological differences, the hip, and joints have been left out of the equation for proper propulsion. This raises the question of how heel-striking elite distance runners can keep up such high paces with a supposedly inefficient and injurious foot strike technique.

Stride length, hip and knee function

Biomechanical factors associated with elite runners include increased hip function, use, and stride length over recreational runners.[36][42] An increase in running speeds causes increased ground reaction forces, and elite distance runners must compensate for this to maintain their pace over long distances.[43] These forces are attenuated through increased stride length via increased hip flexion and extension through decreased ground contact time and more energy being used in propulsion.[43][44][45] With increased propulsion in the horizontal plane, less impact occurs from the decreased force in the vertical plane.[46] Increased hip flexion allows for increased use of the hip extensors through midstance and toe-off, allowing for more force production.[28] The difference even between world-class and national-level 1500-m runners has been associated with more efficient hip joint function.[47] The increase in velocity likely comes from the increased range of motion in hip flexion and extension, allowing for greater acceleration and speed. The hip extensors and extension have been linked to more powerful knee extension during toe-off, contributing to propulsion.[36] Stride length must be appropriately increased with some degree of knee flexion maintained through the terminal swing phases, as excessive knee extension during this phase along with footstrike has been associated with higher impact forces due to braking and an increased prevalence of heel striking.[48] Elite runners tend to exhibit some degree of knee flexion at footstrike and midstance, which first serves to eccentrically absorb impact forces in the quadriceps muscle group.[47][49][50] Secondly it allows for the knee joint to contract concentrically and provides significant aid in propulsion during toe-off as the quadriceps group is capable of producing large amounts of force.[28] Recreational runners have been shown to increase stride length through increased knee extension rather than increased hip flexion, as exhibited by elite runners, which provides an intense braking motion with each step and decreases the rate and efficiency of knee extension during toe-off, slowing down speed.[42] Knee extension, however, contributes to additional stride length and propulsion during toe-off and is seen more frequently in elite runners as well.[36]

The runner's posture should be upright and slightly tilted forward.

Upright posture and slight forward lean

Leaning forward places a runner's center of mass on the front part of the foot, which avoids landing on the heel and facilitates the use of the spring mechanism of the foot. It also makes it easier for the runner to avoid landing the foot in front of the center of mass and the resultant braking effect. While upright posture is essential, a runner should maintain a relaxed frame and use their core to keep posture upright and stable. This helps prevent injury as long as the body is neither rigid nor tense. The most common running mistakes are tilting the chin up and scrunching shoulders.[51]

Stride rate and types

Exercise physiologists have found that the stride rates are extremely consistent across professional runners, between 185 and 200 steps per minute. The main difference between long- and short-distance runners is the length of stride rather than the rate of stride.[52][53]

During running, the speed at which the runner moves may be calculated by multiplying the cadence (steps per minute) by the stride length. Running is often measured in terms of pace,[54] expressed in units of minutes per mile or minutes per kilometer (the inverse of speed, in mph or km/h). Some coaches advocate training at a combination of specific paces related to one's fitness to stimulate various physiological improvements.[55]

Different types of stride are necessary for different types of running. When sprinting, runners stay on their toes bringing their legs up, using shorter and faster strides. Long-distance runners tend to have more relaxed strides that vary.

Health benefits


While there exists the potential for injury while running (just as there is in any sport), there are many benefits. Some of these benefits include potential weight loss, improved cardiovascular and respiratory health (reducing the risk of cardiovascular and respiratory diseases), improved cardiovascular fitness, reduced total blood cholesterol, strengthening of bones (and potentially increased bone density), possible strengthening of the immune system and an improved self-esteem and emotional state.[56] Running, like all forms of regular exercise, can effectively slow[57] or reverse[58] the effects of aging. Even people who have already experienced a heart attack are 20% less likely to develop serious heart problems if more engaged in running or any type of aerobic activity.[59]

Although an optimal amount of vigorous aerobic exercise such as running might bring benefits related to lower cardiovascular disease and life extension, an excessive dose (e.g., marathons) might have an opposite effect associated with cardiotoxicity.[60]

Running can assist people in losing weight, staying in shape and improving body composition. Research suggests that the person of average weight will burn approximately 100 calories per mile run.[61] Running increases one's metabolism, even after running; one will continue to burn an increased level of calories for a short time after the run.[62] Different speeds and distances are appropriate for different individual health and fitness levels. For new runners, it takes time to get into shape. The key is consistency and a slow increase in speed and distance.[61] While running, it is best to pay attention to how one's body feels. If a runner is gasping for breath or feels exhausted while running, it may be beneficial to slow down or try a shorter distance for a few weeks. If a runner feels that the pace or distance is no longer challenging, then the runner may want to speed up or run farther.[63]


Running can also have psychological benefits, as many participants in the sport report feeling an elated, euphoric state, often referred to as a "runner's high".[64] Running is frequently recommended as therapy for people with clinical depression and people coping with addiction.[65] A possible benefit may be the enjoyment of nature and scenery, which also improves psychological well-being[66] (see Ecopsychology § Practical benefits).

In animal models, running has been shown to increase the number of newly created neurons within the brain.[67] This finding could have significant implications in aging as well as learning and memory. A recent study published in Cell Metabolism has also linked running with improved memory and learning skills.[68]

Running is an effective way to reduce stress, anxiety, depression, and inflammation. It helps people who struggle with seasonal affective disorder by running outside when it is sunny and warm. Running can improve mental alertness and sleep.[69] Both research and clinical experience have shown that exercise can be a treatment for serious depression and anxiety even some physicians prescribe exercise to most of their patients.[70] Running can have a longer-lasting effect than anti-depressants.[71] The non-threatening environment offered by running generates a sense of achievement and belonging which helps with mental illness.[72]

High impact

Person with a bad running form. Heel striking and leaning forward are some of the most common mistakes and cause of injuries among beginners.

Many injuries are associated with running because of its high-impact nature. Change in running volume may lead to development of patellofemoral pain syndrome, iliotibial band syndrome, patellar tendinopathy, plica syndrome, and medial tibial stress syndrome. Change in running pace may cause Achilles Tendinitis, gastrocnemius injuries, and plantar fasciitis.[73] Repetitive stress on the same tissues without enough time for recovery or running with improper form can lead to many of the above. Runners generally attempt to minimize these injuries by warming up before exercise,[27] focusing on proper running form, performing strength training exercises, eating a well balanced diet, allowing time for recovery, and "icing" (applying ice to sore muscles or taking an ice bath).

Some runners may experience injuries when running on concrete surfaces. The problem with running on concrete is that the body adjusts to this flat surface running, and some of the muscles will become weaker, along with the added impact of running on a harder surface. Therefore, it can be beneficial to change terrain occasionally – such as trail, beach, or grass running. This is more unstable ground and allows the legs to strengthen different muscles. Runners should be wary of twisting their ankles on such terrain. Running downhill also increases knee stress and should, therefore, be avoided. Reducing the frequency and duration can also prevent injury.

Barefoot running has been promoted as a means of reducing running related injuries,[74] but this remains controversial and a majority of professionals advocate the wearing of appropriate shoes as the best method for avoiding injury.[75] However, a study in 2013 concluded that wearing neutral shoes is not associated with increased injuries.[76]


Chafing of skin following a marathon run

Another common, running-related injury is chafing, caused by repetitive rubbing of one piece of skin against another, or against an article of clothing. One common location for chafe to occur is the runner's upper thighs. The skin feels coarse and develops a rash-like look. A variety of deodorants and special anti-chafing creams are available to treat such problems. Chafe is also likely to occur on the nipple. There are a variety of home remedies that runners use to deal with chafing while running such as band-aids and using grease to reduce friction. Prevention is key which is why form fitting clothes are important.[77]

Iliotibial band syndrome

An iliotibial band is a muscle and tendon that is attached to the hip and runs the length of the thigh to attach to the upper part of the tibia, and the band is what helps the knee to bend. This is an injury that is located at the knee and shows symptoms of swelling outside the knee. Iliotibial band syndrome is also known as "runner's knee" or "jogger's knee" because it can be caused by jogging or running. Once pain or swelling is noticeable it is important to put ice on it immediately and it is recommended to rest the knee for better healing.[78] Most knee injuries can be treated by light activity and much rest for the knee. In more serious cases, arthroscopy is the most common to help repair ligaments but severe situations reconstructive surgery would be needed.[79] A survey was taken in 2011 with knee injuries being 22.7% of the most common injuries.[80]

Medial tibial stress syndrome

A more known injury is medial tibial stress syndrome (MTSS) which is the accurate name for shin splints. This is caused during running when the muscle is being overused along the front of the lower leg with symptoms that affect 2 to 6 inches of the muscle. Shin Splints have sharp, splinter-like pain, that is typically X-rayed by doctors but is not necessary for shin splints to be diagnosed. To help prevent shin splints it is commonly known to stretch before and after a workout session, and also avoid heavy equipment especially during the first couple of workout sessions.[81] Also to help prevent shin splints do not increase the intensity of a workout more than 10% a week.[82] To treat shin splints it is important to rest with the least amount of impact on your legs and apply ice to the area. A survey showed that shin splints make up 12.7% of the most common injuries in running, with blisters being the top percentage at 30.9%.[80]


Competitors in the men's 10,000-metre run at the 2012 Summer Olympics.

Running is both a competition and a type of training for sports that have running or endurance components. As a sport, it is split into events divided by distance and sometimes includes permutations such as the obstacles in steeplechase and hurdles. Running races are contests to determine which of the competitors is able to run a certain distance in the shortest time. Today, competitive running events make up the core of the sport of athletics. Events are usually grouped into several classes, each requiring substantially different athletic strengths and involving different tactics, training methods, and types of competitors.

Running competitions have probably existed for most of humanity's history and were a key part of the ancient Olympic Games as well as the modern Olympics. The activity of running went through a period of widespread popularity in the United States during the running boom of the 1970s. Over the next two decades, as many as 25 million Americans were doing some form of running or jogging – accounting for roughly one tenth of the population.[83] Today, road racing is a popular sport among non-professional athletes, who included over 7.7 million people in America alone in 2002.[84]

Limits of speed

Footspeed, or sprint speed, is the maximum speed at which a human can run. It is affected by many factors, varies greatly throughout the population, and is important in athletics and many sports.

The fastest human footspeed on record is 44.7 km/h (12.4 m/s; 27.8 mph), seen during a 100-meter sprint (average speed between the 60th and the 80th meter) by Usain Bolt.[85]

Main article: Track running

A man running with a baton during a relay race.

Track running events are individual or relay events with athletes racing over specified distances on an oval running track. The events are categorized as sprints, middle and long-distance, and hurdling.


Main article: Road running

Road running takes place on a measured course over an established road (as opposed to track and cross country running). These events normally range from distances of 5 kilometers to longer distances such as half marathons and marathons, and they may involve scores of runners or wheelchair entrants.


Main articles: Cross country running, Fell running, and Trail running

Cross country running takes place over the open or rough terrain. The courses used for these events may include grass, mud, woodlands, hills, flat ground and water. It is a popular participatory sport and is one of the events which, along with track and field, road running, and racewalking, makes up the umbrella sport of athletics.


Main articles: Fell running, Mountain running, Skyrunning, Trail running, and Tower running

The majority of popular races do not incorporate a significant change in elevation as a key component of a course. There are several, disparate variations that feature significant inclines or declines. These fall into two main groups.

The naturalistic group is based on outdoor racing over geographical features. Among these are the cross country-related sports of fell running (a tradition associated with Northern Europe) and trail running (mainly ultramarathon distances), the running/climbing combination of skyrunning (organised by the International Skyrunning Federation with races across North America, Europe and East Asia) and the mainly trail- and road-centred mountain running (governed by the World Mountain Running Association and based mainly in Europe).

The second variety of vertical running is based on human structures, such as stairs and man-made slopes. The foremost type of this is tower running, which sees athletes compete indoors, running up steps within very tall structures such as the Eiffel Tower or Empire State Building.



Main article: Sprint (running)

International-level women athletes competing in 100 m sprint race at ISTAF Berlin, 2006

Sprints are short running events in athletics and track and field. Races over short distances are among the oldest running competitions. The first 13 editions of the Ancient Olympic Games featured only one event – the stadion race, which was a race from one end of the stadium to the other.[86] There are three sprinting events which are currently held at the Olympics and outdoor World Championships: the 100 metres, 200 metres, and 400 metres. These events have their roots in races of imperial measurements which were later altered to metric: the 100 m evolved from the 100-yard dash,[87] the 200 m distances came from the furlong (or 1/8 of a mile),[88] and the 400 m was the successor to the 440-yard dash or quarter-mile race.[89]

At the professional level, sprinters begin the race by assuming a crouching position in the starting blocks before leaning forward and gradually moving into an upright position as the contest progresses and momentum is gained.[90] Athletes remain in the same lane on the running track throughout all sprinting events,[89] with the sole exception of the 400 m indoors. Races up to 100 m are largely focused upon acceleration to an athlete's maximum speed.[90] All sprints beyond this distance increasingly incorporate an element of endurance.[91] Human physiology dictates that a runner's near-top speed cannot be maintained for more than thirty seconds or so as lactic acid builds up, and leg muscles begin to be deprived of oxygen.[89]

The 60 metres is a common indoor event and it an indoor world championship event. Other less-common events include the 50 metres, 55 metres, 300 metres and 500 metres which are used in some high and collegiate competitions in the United States. The 150 metres, is rarely competed: Pietro Mennea set a world best in 1983,[92] Olympic champions Michael Johnson and Donovan Bailey went head-to-head over the distance in 1997,[93] and Usain Bolt improved Mennea's record in 2009.[92]

Middle distance

Main article: Middle-distance running

Middle-distance running events are track races longer than sprints up to 3000 metres. The standard middle distances are the 800 metres, 1500 metres and mile run, although the 3000 metres may also be classified as a middle-distance event.[94] The 880-yard run, or half-mile, was the forebear to the 800 m distance and it has its roots in competitions in the United Kingdom in the 1830s.[95] The 1500 m came about as a result of running three laps of a 500 m track, which was commonplace in continental Europe in the 1900s.[96]

Long distance

Main article: Long-distance running

Examples of longer-distance running events are long-distance track races, half marathons, marathons, ultramarathons, and multiday races.
