Walking (also known as ambulation) is one of the main gaits of locomotion among legged animals, and is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the number of limbs - even arthropods, with six, eight or more limbs, walk.
In the United Kingdom and Ireland, the term walking includes activities such as walking in a park and trekking in the Alps. However, in Canada and the United States the term for a long, vigorous walk is hiking, while the word walking covers shorter walks, especially in an urban setting.[1]

Difference from running
Main article: Running
See also: Jogging
Racewalkers at the World Cup Trials in 1987
The word walk is descended from the Old English wealcan "to roll". In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal species, there are numerous gaits which may be termed walking or running, and distinctions based upon the presence or absence of a suspended phase or the number of feet in contact any time do not yield mechanically correct classification.[2] The most effective method to distinguish walking from running is to measure the height of a person's centre of mass using motion capture or a force plate at midstance. During walking, the centre of mass reaches a maximum height at midstance, while during running, it is then at a minimum. This distinction, however, only holds true for locomotion over level or approximately level ground. For walking up grades above 9%, this distinction no longer holds for some individuals. Definitions based on the percentage of the stride during which a foot is in contact with the ground (averaged across all feet) of greater than 50% contact corresponds well with identification of 'inverted pendulum' mechanics and are indicative of walking for animals with any number of limbs, although this definition is incomplete.[2] Running humans and animals may have contact periods greater than 50% of a gait cycle when rounding corners, running uphill or carrying loads.
Speed is another factor that distinguishes walking from running. Although walking speeds can vary greatly depending on many factors such as height, weight, age, terrain, surface, load, culture, effort, and fitness, the average human walking speed is about 5.0 kilometres per hour (km/h), or about 3.1 miles per hour (mph). Specific studies have found pedestrian walking speeds ranging from 4.51 kilometres per hour (2.80 mph) to 4.75 kilometres per hour (2.95 mph) for older individuals and from 5.32 kilometres per hour (3.31 mph) to 5.43 kilometres per hour (3.37 mph) for younger individuals;[3][4] a brisk walking speed can be around 6.5 kilometres per hour (4.0 mph).[5] Champion racewalkers can average more than 14 kilometres per hour (8.7 mph) over a distance of 20 kilometres (12 mi). An average human child achieves independent walking ability at around 11 months old.[6]
Health benefits of walking
Main article: Physical exercise
Regular, brisk exercise of any kind can improve confidence, stamina, energy, weight control and life expectancy and reduce stress. It can also reduce the risk of coronary heart disease, strokes, diabetes, high blood pressure, bowel cancer and osteoporosis. Scientific studies have also shown that walking, besides its physical benefits, is also beneficial for the mind, improving memory skills, learning ability, concentration and abstract reasoning, as well as reducing stress and lifting spirits. Sustained walking sessions for a minimum period of thirty to sixty minutes a day, five days a week, with the correct walking posture,[7][8] reduce health risks and have various overall health benefits,[9] such as reducing the chances of cancer, type 2 diabetes, heart disease, anxiety and depression.[10] Life expectancy is also increased even for individuals suffering from obesity or high blood pressure. Walking also improves bone health, especially strengthening the hip bone, and lowering the harmful low-density lipoprotein (LDL) cholesterol, and raising the useful high-density lipoprotein (HDL) cholesterol.[11] Studies have found that walking may also help prevent dementia and Alzheimer's.[12]
The Centers for Disease Control and Prevention's fact sheet on the "Relationship of Walking to Mortality Among U.S. Adults with Diabetes" states that those with diabetes who walked for 2 or more hours a week lowered their mortality rate from all causes by 39 per cent. "Walking lengthened the life of people with diabetes regardless of age, sex, race, body mass index, length of time since diagnosis, and presence of complications or functional limitations."[13] It has been suggested that there is a relationship between the speed of walking and health, and that the best results are obtained with a speed of more than 2.5 mph (4 km/h).[14]
Governments now recognize the benefits of walking for mental and physical health and are actively encouraging it. This growing emphasis on walking has arisen because people walk less nowadays than previously. In the UK; a Department of Transport report[15] found that between 1995/97 and 2005 the average number of walk trips per person fell by 16%, from 292 to 245 per year. Many professionals in local authorities and the NHS are employed to halt this decline by ensuring that the built environment allows people to walk and that there are walking opportunities available to them. Professionals working to encourage walking come mainly from six sectors: health, transport, environment, schools, sport and recreation, and urban design.
One programme to encourage walking is "The Walking the Way to Health Initiative", organized by the British walkers association The Ramblers, which is the largest volunteer led walking scheme in the United Kingdom. Volunteers are trained to lead free Health Walks from community venues such as libraries and doctors' surgeries. The scheme has trained over 35,000 volunteers and have over 500 schemes operating across the UK, with thousands of people walking every week.[16] A new organization called "Walk England" launched a web site in June 2008 to provide these professionals with evidence, advice and examples of success stories of how to encourage communities to walk more. The site has a social networking aspect to allow professionals and the public to ask questions, post news and events and communicate with others in their area about walking, as well as a "walk now" option to find out what walks are available in each region. Similar organizations exist in other countries and recently a "Walking Summit" was held in the USA. This "assembl[ed] thought-leaders and influencers from business, urban planning and real estate, [along with] physicians and public health officials," and others, to discuss how to make American cities and communities places where "people can and want to walk".[17]
Origins
It is theorized that "walking" among tetrapods originated underwater with air-breathing fish that could "walk" underwater, giving rise to the plethora of land-dwelling life that walk on four or two limbs.[18] While terrestrial tetrapods are theorised to have a single origin, arthropods and their relatives are thought to have independently evolved walking several times, specifically in insects, myriapods, chelicerates, tardigrades, onychophorans, and crustaceans.[19]
Judging from footprints discovered on a former shore in Kenya, it is thought possible that ancestors of modern humans were walking in ways very similar to the present activity as many as 1.5 million years ago.[20][21]
Variants of walking
- Scrambling is a method of ascending a hill or mountain that involves using both hands, because of the steepness of the terrain.[22] Of necessity it will be a slow and careful form of walking and with possibly of occasional brief, easy rock climbing. Some scrambling takes place on narrow exposed ridges where more attention to balance will be required than in normal walking
- Snow shoeing—A snowshoe is footwear for walking over the snow. Snowshoes work by distributing the weight of the person over a larger area so that the person's foot does not sink completely into the snow, a quality called "flotation". It is often said by snowshoers that if you can walk, you can snowshoe. This is true in optimal conditions, but snowshoeing properly requires some slight adjustments to walking. The method of walking is to lift the shoes slightly and slide the inner edges over each other, thus avoiding the unnatural and fatiguing "straddle-gait" that would otherwise be necessary. A snowshoer must be willing to roll his or her feet slightly as well. An exaggerated stride works best when starting out, particularly with larger or traditional shoes.
- Nordic walking is a physical activity and a sport, which is performed with specially designed walking poles similar to ski poles. Compared to regular walking, Nordic walking (also called pole walking) involves applying force to the poles with each stride. Nordic walkers use more of their entire body (with greater intensity) and receive fitness building stimulation not present in normal walking for the chest, lats, triceps, biceps, shoulder, abdominals, spinal and other core muscles that may result in significant increases in heart rate at a given pace.[23] Nordic walking has been estimated as producing up to a 46% increase in energy consumption, compared to walking without poles.[24][25]
- Pedestrianism is a sport that developed during the late eighteenth and nineteenth centuries, and was a popular spectator sport in the British Isles. By the end of the 18th century, and especially with the growth of the popular press, feats of foot travel over great distances (similar to a modern Ultramarathon) gained attention, and were labeled "pedestrianism". Interest in the sport, and the wagering which accompanied it, spread to the United States, Canada, and Australia in the 19th century. By the end of the 19th century, Pedestrianism was largely displaced by the rise in modern spectator sports and by controversy involving rules, which limited its appeal as a source of wagering and led to its inclusion in the amateur athletics movement. Pedestrianism was first codified in the last half of the 19th century, evolving into what would become racewalking, By the mid 19th century, competitors were often expected to extend their legs straight at least once in their stride, and obey what was called the "fair heel and toe" rule. This rule, the source of modern racewalking, was a vague commandment that the toe of one foot could not leave the ground before the heel of the next foot touched down. This said, rules were customary and changed with competition. Racers were usually allowed to jog in order to fend off cramps, and it was distance, not code, which determined gait for longer races. Newspaper reports suggest that "trotting" was common in events.[26]
- Racewalking is a long-distance athletic event. Although it is a foot race, it is different from running in that one foot must appear to be in contact with the ground at all times. Stride length is reduced, so to achieve competitive speeds, racewalkers must attain cadence rates comparable to those achieved by Olympic 800-meter runners,[27] and they must do so for hours at a time since the Olympic events are the 20 km (12.4 mi) race walk (men and women) and 50 km (31 mi) race walk (men only), and 50 mile (80.5 km) events are also held. See also Pedestrianism above.
- Power walking or speed walking is the act of walking with a speed at the upper end of the natural range for walking gait, typically 7 to 9 km/h (4.5 to 5.5 mph). To qualify as power walking as opposed to jogging or running, at least one foot must be in contact with the ground at all times.(See also Fitwalking).
- Beach Walking is a sport that developed from the Beach Run competitions of the 1960s. It can take place on either compact or non-compact sand and involves a specific walking technique.
Biomechanics
Human walking is accomplished with a strategy called the double pendulum. During forward motion, the leg that leaves the ground swings forward from the hip. This sweep is the first pendulum. Then the leg strikes the ground with the heel and rolls through to the toe in a motion described as an inverted pendulum. The motion of the two legs is coordinated so that one foot or the other is always in contact with the ground. The process of walking recovers approximately sixty per cent of the energy used due to pendulum dynamics and ground reaction force.[28][29]
Walking differs from a running gait in a number of ways. The most obvious is that during walking one leg always stays on the ground while the other is swinging. In running there is typically a ballistic phase where the runner is airborne with both feet in the air (for bipedals).
Another difference concerns the movement of the centre of mass of the body. In walking the body "vaults" over the leg on the ground, raising the centre of mass to its highest point as the leg passes the vertical, and dropping it to the lowest as the legs are spread apart. Essentially kinetic energy of forward motion is constantly being traded for a rise in potential energy. This is reversed in running where the centre of mass is at its lowest as the leg is vertical. This is because the impact of landing from the ballistic phase is absorbed by bending the leg and consequently storing energy in muscles and tendons. In running there is a conversion between kinetic, potential, and elastic energy.
There is an absolute limit on an individual's speed of walking (without special techniques such as those employed in speed walking) due to the upwards acceleration of the centre of mass during a stride - if it's greater than the acceleration due to gravity the person will become airborne as they vault over the leg on the ground. Typically however, animals switch to a run at a lower speed than this due to energy efficiencies.
A leisure activity

Main article: Hiking
Many people enjoy walking as a recreation in the mainly urban modern world, and it is one of the best forms of exercise.[30] For some, walking is a way to enjoy nature and the outdoors; and for others the physical, sporting and endurance aspect is more important.
There are a variety of different kinds of walking, including bushwalking, racewalking, beach walking, hillwalking, volksmarching, Nordic walking, trekking and hiking. Some people prefer to walk indoors on a treadmill, or in a gym, and fitness walkers and others may use a pedometer to count their steps. Hiking is the usual word used in Canada, the USA and South Africa for long vigorous walks; similar walks are called tramps in New Zealand, or hill walking or just walking in Australia, the UK and the Irish Republic. Australians also bushwalk. In English-speaking parts of North America the term walking is used for short walks, especially in towns and cities. Snow shoeing is walking in snow; a slightly different gait is required compared with regular walking.
In terms of tourism the possibilities range from guided walking tours in cities, to organized trekking holidays in the Himalayas. In the UK the term walking tour also refers to a multi-day walk or hike undertaken by a group or individual. Well-organized systems of trails exist in many other European counties, as well as Canada, USA, New Zealand, and Nepal. Systems of lengthy waymarked walking trails now stretch across Europe from Norway to Turkey, Portugal to Cyprus.[31] Many also walk the traditional pilgrim routes, of which the most famous is El Camino de Santiago, The Way of St. James.
Numerous walking festivals and other walking events take place each year in many countries. The world's largest multi-day walking event is the International Four Days Marches Nijmegen in the Netherlands. The "Vierdaagse" (Dutch for "Four day Event") is an annual walk that has taken place since 1909; it has been based at Nijmegen since 1916. Depending on age group and category, walkers have to walk 30, 40 or 50 kilometers each day for four days.[citation needed] Originally a military event with a few civilians, it now is a mainly civilian event. Numbers have risen in recent years, with over 40,000 now taking part, including about 5,000 military personnel.[citation needed] Due to crowds on the route, since 2004 the organizers have limited the number of participants. In the USA there is the annual Labor Day walk on Mackinac Bridge, Michigan, which draws over 60,000 participants; it is the largest single-day walking event;[citation needed] while the Chesapeake Bay Bridge Walk in Maryland draws over 50,000 participants each year.[citation needed] There are also various walks organised as charity events, with walkers sponsored for a specific cause. Thes walks range in length from two miles (3 km) or five km to 50 miles (80 km). The MS Challenge Walk is a 80 km or 50 mile walk which raises money to fight multiple sclerosis, while walkers in the Oxfam Trailwalker cover 100 km or 60 miles.
In Britain, The Ramblers, a registered charity, is the largest organisation that looks after the interests of walkers, with some 139,000 members.[citation needed] Its "Get Walking Keep Walking" project provides free route guides, led walks, as well as information for people new to walking.[32] The Long Distance Walkers Association in the UK is for the more energetic walker, and organizes lengthy challenge hikes of 20 or even 50 miles (30 to 80 km) or more in a day. The LDWA's annual "Hundred" event, entailing walking 100 miles or 160 km in 48 hours, takes place each British Spring Bank Holiday weekend.[33]
Walkability
Main article: Walkability
Gauchetière Street, Montreal, Canada
There has been a recent focus among urban planners in some communities to create pedestrian-friendly areas and roads, allowing commuting, shopping and recreation to be done on foot. The concept of walkability has arisen as a measure of the degree to which an area is friendly to walking. Some communities are at least partially car-free, making them particularly supportive of walking and other modes of transportation. In the United States, the active living network is an example of a concerted effort to develop communities more friendly to walking and other physical activities.
An example of such efforts to make urban development more pedestrian friendly is the pedestrian village. This is a compact, pedestrian-oriented neighborhood or town, with a mixed-use village center, that follows the tenets of New Pedestrianism.[34][35] Shared-use lanes for pedestrians and those using bicycles, Segways, wheelchairs, and other small rolling conveyances that do not use internal combustion engines. Generally, these lanes are in front of the houses and businesses, and streets for motor vehicles are always at the rear. Some pedestrian villages might be nearly car-free with cars either hidden below the buildings or on the periphery of the village. Venice, Italy is essentially a pedestrian village with canals.The canal district in Venice, California, on the other hand, combines the front lane/rear street approach with canals and walkways, or just walkways.[34][36][37]
Walking is also considered to be a clear example of a sustainable mode of transport, especially suited for urban use and/or relatively shorter distances. Non-motorised transport modes such as walking, but also cycling, small-wheeled transport (skates, skateboards, push scooters and hand carts) or wheelchair travel are often key elements of successfully encouraging clean urban transport.[38] A large variety of case studies and good practices (from European cities and some worldwide examples) that promote and stimulate walking as a means of transportation in cities can be found at Eltis, Europe's portal for local transport.[39]
The development of specific rights of way with appropriate infrastructure can promote increased participation and enjoyment of walking. Examples of types of investment include pedestrian malls, and foreshoreways such as oceanways and also river walks.
The first purpose-built pedestrian street in Europe is the Lijnbaan in Rotterdam, opened in 1953. The first pedestrianised shopping centre in the United Kingdom was in Stevenage in 1959. A large number of European towns and cities have made part of their centres car-free since the early 1960s. These are often accompanied by car parks on the edge of the pedestrianised zone, and, in the larger cases, park and ride schemes. Central Copenhagen is one of the largest and oldest: It was converted from car traffic into pedestrian zone in 1962.

The first successful attempts at walking robots tended to have six legs. The number of legs was reduced as microprocessor technology advanced, and there are now a number of robots that can walk on two legs. One, for example, is ASIMO. Although robots have taken great strides in advancement, they still don't walk nearly as well as human beings as they often need to keep their knees bent permanently in order to improve stability.
In 2009, Japanese roboticist Tomotaka Takahashi developed a robot that can jump three inches off the ground. The robot, named Ropid, is capable of getting up, walking, running, and jumping.[40]

Horses
Main article: Horse gait
The walk, a four-beat gait
The walk is a four-beat gait that averages about 4 miles per hour (6.4 km/h). When walking, a horse's legs follow this sequence: left hind leg, left front leg, right hind leg, right front leg, in a regular 1-2-3-4 beat. At the walk, the horse will always have one foot raised and the other three feet on the ground, save for a brief moment when weight is being transferred from one foot to another. A horse moves its head and neck in a slight up and down motion that helps maintain balance.[41]
Ideally, the advancing rear hoof oversteps the spot where the previously advancing front hoof touched the ground. The more the rear hoof oversteps, the smoother and more comfortable the walk becomes. Individual horses and different breeds vary in the smoothness of their walk. However, a rider will almost always feel some degree of gentle side-to-side motion in the horse's hips as each hind leg reaches forward.
The fastest "walks" with a four-beat footfall pattern are actually the lateral forms of ambling gaits such as the running walk, singlefoot, and similar rapid but smooth intermediate speed gaits. If a horse begins to speed up and lose a regular four-beat cadence to its gait, the horse is no longer walking, but is beginning to either trot or pace.
Elephants
An Asian elephant walking
Elephants can move both forwards and backwards, but cannot trot, jump, or gallop. They use only two gaits when moving on land, the walk and a faster gait similar to running.[42] In walking, the legs act as pendulums, with the hips and shoulders rising and falling while the foot is planted on the ground. With no "aerial phase", the fast gait does not meet all the criteria of running, although the elephant uses its legs much like other running animals, with the hips and shoulders falling and then rising while the feet are on the ground.[43] Fast-moving elephants appear to 'run' with their front legs, but 'walk' with their hind legs and can reach a top speed of 18 km/h (11 mph).[44] At this speed, most other quadrupeds are well into a gallop, even accounting for leg length.
Walking fish
A mudskipper, a type of walking fish, perched on land.
Walking fish, sometimes called ambulatory fish, is a general term that refers to fish that are able to travel over land for extended periods of time. The term may also be used for some other cases of nonstandard fish locomotion, e.g., when describing fish "walking" along the sea floor, as the handfish or frogfish.
