62-463: Vivian Jepkemoi Cheruiyot (born 11 September 1983) is a Kenyan long-distance runner . She represented Kenya at the Summer Olympics in 2000, 2008, 2012, and 2016, winning the silver medal in the 5,000 metres and bronze in the 10,000 metres at the 2012 London Olympics as well as gold in the 5,000 m and silver in the 10,000 m at the 2016 Rio Olympics , setting a new Olympic record in

124-532: A historic method for hunting among the San of the Kalahari , American Indians , and Aboriginal Australians . In this method, the hunter would run at a slow and steady pace for between one hour and a few days, in an area where the animal has no place to hide. The animal, running in spurts, has to stop to pant to cool itself, but as the chase goes on it would not have enough time before it has to start running again, and after

186-410: A marathon runner's ability to sustain higher intensities for longer periods of time. The prolonged sustenance of running intensity is attributed to a high turnover rate of fatty acids that allows the runner to preserve glycogen stores later into the race. Long-distance runners generally practice carbohydrate loading in their training and race preparation. The maintenance of core body temperature

248-565: A mascot follows on from the mainstream success of the 2009 World Championships in Athletics mascot – Berlino the Bear . The IAAF extended live audio and video coverage of the championships to the internet for certain countries, including a deal with IEC in Sports which saw events available live and on-demand via Dailymotion . This was the first deal of its kind for the competition. Anna Alminova ,

310-730: A means to improve cardiovascular health. Endurance running is often a component of physical military training . Long-distance running as a form of tradition or ceremony is known among the Hopi and Tarahumara people , among others. In the sport of athletics , long-distance events are defined as races covering 3 km (1.9 mi) and above. The three most common types are track running , road running , and cross country running , all of which are defined by their terrain – all-weather tracks , roads, and natural terrain, respectively. Anthropological observations of modern hunter-gatherer communities have provided accounts for long-distance running as

372-504: A number of outdoor 5,000 m titles that year, becoming Commonwealth Games , African and Continental Cup champion, as well as winning the Diamond League title. She is a three-time Diamond League champion, having also won the 2011 and 2012 editions. She is the Kenyan record holder for the 2,000 m and 10,000 m. In 2012, Cheruiyot was voted Laureus World Sportswoman of

434-591: A place in the Kenyan squad and, in contrast to her successes on the track, she was looking to win her first cross country medal on the world stage. Her rival Masai led the initial charge at the World Cross Country Championships, but Cheruiyot broke away on the final lap to secure the gold medal and lead Kenya to the women's team title. She started 2012 with a win at the World's Best 10K and improved her best on

496-425: A race, and the amount of hemoglobin in the blood. Other physiological factors affecting a marathon runner's aerobic capacity include pulmonary diffusion , mitochondria enzyme activity, and capillary density. A long-distance runner's running economy is their steady state requirement for oxygen at specific speeds and helps explain differences in performance for runners with very similar aerobic capacities. This

558-459: A result of these factors, weather can play an integral role in racing conditions. Cross country is both an individual and team sport, as runners are judged on an individual basis and a points-scoring method is used for teams. Competitions are typically races of 4 km (2.5 mi) or more which are usually held in autumn and winter. Cross country's most successful athletes often compete in long-distance track and road events as well. The history of

620-453: A time of 2:18:31. She took second place in the 2018 New York City Marathon , finishing in 2:26:02 far behind winner Mary Keitany in 2:22:48, and 20 seconds ahead of Shalane Flanagan who ran 2:26:22. All information taken from World Athletics profile. Long-distance running Long-distance running , or endurance running , is a form of continuous running over distances of at least 3 km (1.9 mi). Physiologically, it

682-566: A while would collapse from exhaustion and heat. The skeletal structure of a 12-year-old Nariokatome boy has been suggested as proof that early humans from 1.5 million years ago ate more meat and fewer plants, and hunted by running down animals. With developments in agriculture and culture, long-distance running took more and more purposes other than hunting: religious ceremonies, delivering messages for military and political purposes, and sport. Running messengers are reported from early Sumer , were named lasimu as military men as well as

744-457: Is a combination of cycling and distance running. Previous versions of the modern pentathlon incorporated a three or four-kilometre (1.9–2.5 mi) run, but changes to the official rules in 2008 meant the running sections are now divided into three separate legs of one kilometre each (0.6 mi). Depending on the rules and terrain, navigation sports such as foot orienteering and rogaining may contain periods of endurance running within

806-403: Is also found in migratory ungulates and a limited number of terrestrial carnivores, such as bears, dogs, wolves , and hyenas . In modern human society, long-distance running has multiple purposes: people may engage in it for physical exercise , for recreation , as a means of travel, as a competitive sport, for economic reasons, or cultural reasons. Long-distance running can also be used as

868-412: Is crucial to a marathon runner's performance and health. An inability to reduce rising core body temperature can lead to hyperthermia . In order to reduce body heat, the metabolically produced heat needs to be removed from the body via sweating, which in turn requires rehydration to compensate for. Replacement of fluid is limited but can help keep the body's internal temperatures cooler. Fluid replacement

930-407: Is energy consumption during locomotion. While walking, humans use about half the energy needed to run. One's aerobic capacity or VO 2 Max is the ability to maximally take up and consume oxygen during exhaustive exercise. Long-distance runners typically perform at around 75–85% of peak aerobic capacity, while short-distance runners perform at closer to 100% of peak. Aerobic capacity depends on

992-554: Is exclusively found in racing sports . Most of these are individual sports , although team and relay forms also exist. The most prominent long-distance running sports are grouped within the sport of athletics , where running competitions are held on strictly defined courses, and the fastest runner to complete the distance wins. The foremost types are long-distance track running , road running and cross-country running . Other less popular variants such as fell running , trail running , mountain running , and tower running combine

1054-408: Is largely aerobic in nature and requires stamina as well as mental strength. Within endurance running comes two different types of respiration . The more prominent side that runners experience more frequently is aerobic respiration. This occurs when oxygen is present, and the body can utilize oxygen to help generate energy and muscle activity. On the other side, anaerobic respiration occurs when

1116-407: Is often measured by the volume of oxygen consumed, either in liters or milliliters, per kilogram of body weight per minute (L/kg/min or mL/kg/min). As of 2016 the physiological basis for this was uncertain, but it seemed to depend on the cumulative years of running and reaches a cap that longer individual training sessions cannot overcome. A long-distance runner's velocity at the lactate threshold

1178-811: Is physiologically challenging during the exercise of this intensity due to the inefficient emptying of the stomach. Partial fluid replacement can serve to avoid a marathon runner's body overheating but not enough to keep pace with the loss of fluid via sweat evaporation. Environmental factors can especially complicate heat regulation. Since the late 1980s, Kenyans, Moroccans, and Ethiopians have dominated in major international long-distance competitions. The high altitude of these countries has been proven to help these runners achieve more success. High altitude, combined with endurance training, can lead to an increase in red blood cells, allowing increased oxygen delivery via arteries. The majority of these East African successful runners come from three mountain districts that run along

1240-503: Is strongly correlated to their performance. The lactate threshold is the cross-over point between predominantly aerobic energy usage and anaerobic energy usage and is considered a good indicator of the body's ability to efficiently process and transfer chemical energy into mechanical energy . For most runners, the aerobic zone does not begin until around 120 heartbeats per minute. Lactate threshold training involves tempo workouts that are meant to build strength and speed, rather than improve

1302-401: The 1912 Summer Olympics . Fell running , trail running , and mountain running can all be considered variations on the traditional cross country which incorporate significant uphill and/or downhill sections as an additional challenge to the course. The term adventure running is loosely defined and can be used to describe any form of long-distance running in a natural setting, regardless of

1364-653: The 2010 IAAF World Indoor Championships resulted in a silver medal in the 3000 m behind Meseret Defar. Cheruiyot then headed the Kenyan 5000 m challenge at the African Championships in Athletics in Nairobi and beat Defar on this occasion to take the African title. After this, her main focus of the year was the Diamond League . She took victories in the 5000 m at the Meeting Areva and Memorial van Damme and

1426-459: The Great Rift Valley . While altitude may be a contributing factor, a culture of hard work, teamwork, as well as an advanced institutional structure also contributes to their success. "… an evolutionary perspective indicates that we did not evolve to run long distances at fast speeds on a regular basis. As a result, it is unlikely there was a selection for the human body to cope with some of

1488-628: The Summer Paralympics . The World Marathon Majors series includes the six most prestigious marathon competitions at the elite level – the Berlin , Boston , Chicago , London , Tokyo , and New York City marathons. The Tokyo Marathon was most recently added to the World Marathon Majors in 2012. Ekiden contests – which originated in Japan and remain common there – are a relay race variation on

1550-906: The Tuskys Cross Country meeting. She ended the year on a high note with a win at the BOclassic 5K race on New Year's Eve. Cheruiyot began preparing for the World Cross Country Championships in January 2011 and came third at the Great Edinburgh Cross Country before overhauling Linet Masai to win the Cross de Itálica in Seville. A second-place finish at the Kenyan Cross Country Championships guaranteed her

1612-503: The 20th century: the oval running tracks were standardised to 400 metres in distance and cinder tracks were replaced by synthetic all-weather running track of asphalt and rubber from the mid-1960s onwards. It was not until the 1912 Stockholm Olympics that the standard long-distance track events of 5000 metres and 10,000 metres were introduced. Long-distance road running competitions are mainly conducted on courses of paved or tarmac roads, although major events often finish on

1674-719: The United States made road running a common pastime and also increased its popularity at the elite level. The marathon is the only road running event featured at the World Athletics Championships and the Summer Olympics , although there is also the World Athletics Half Marathon Championships held every two years. The marathon is also the only road running event featured at the World Para Athletics Championships and

1736-400: The United States, men race 8,000 or 10,000 meters, depending on their division, whereas women race 6,000 meters. The Summer Olympics features four long-distance running events: the 3000 metres steeplechase (which also involves jumping over barriers and water), the 5000 metres , 10,000 metres and marathon (42.195 kilometres, or 26 miles and 385 yards). Humans have been considered among

1798-528: The Year . Vivian Cheruiyot is trained by Ricky Simms. She was born near Keiyo in the Rift Valley Province , coming from the same village as another female runner Alice Timbilili . Her breakthrough year came in 1999: at the age of fifteen she took the junior silver medal at the 1999 IAAF World Cross Country Championships behind Werknesh Kidane . At the 1999 World Youth Championships in Athletics she won

1860-459: The best distance runners among all running animals: game animals are faster over short distances, but they have less endurance than humans. Unlike other primates whose bodies are suited to walk on four legs or climb trees, the human body has evolved into upright walking and running around 2-3 million years ago. The human body can endure long-distance running through the following attributes: One distinction between upright walking and running

1922-408: The body is deprived of oxygen, and this is common towards the final stretch of races when there is a drive to speed up to a greater intensity. Overall, both types of respiration are used by endurance runners quite often but are very different from each other. Among mammals , humans are well adapted for running significant distances, particularly so among primates . The capacity for endurance running

1984-413: The bronze medal in the 3000 metres . Cheruiyot earned a senior call-up for the 1999 All-Africa Games , where she managed a bronze medal in the 5000 metres . She became the junior champion at the 2000 IAAF World Cross Country Championships . Cheruiyot gained selection for the 2000 Olympic Games and reached the 5000 m final after setting personal bests in the qualifying rounds. She was much slower in

2046-426: The cardiovascular system's efficiency in absorbing and transporting oxygen. By running at your lactate threshold, your body will become more efficient at clearing lactate and reusing it to fuel your muscles. Uncertainty exists in regard to how lactate threshold affects endurance performance. In order to sustain high-intensity running, a marathon runner must obtain sufficient glycogen stores. Glycogen can be found in

2108-469: The carriages of aristocrats around the 18th century, and who also ran errands over distances for their masters. Foot racing competitions evolved from wagers between aristocrats, who pitted their footman against that of another aristocrat in order to determine a winner. The sport became professionalised as footmen were hired specifically on their athletic ability and began to devote their lives to training for gambling events. The amateur sports movement in

2170-499: The challenge of distance with a significant incline or change of elevation as part of the course. Multisport races frequently include endurance running. Triathlon , as defined by the International Triathlon Union , may feature running sections ranging from five kilometres (3.1 miles) to the marathon distance (42.195 kilometres, or 26 miles and 385 yards), depending on the race type . The related sport of duathlon

2232-443: The competition. Variants of adventure racing may also combine navigational skills and endurance running in this manner. The history of long-distance track running events are tied to the track and field stadia where they are held. Oval circuits allow athletes to cover long distances in a confined area. Early tracks were usually on flattened earth or were simply marked areas of grass. The style of running tracks became refined during

2294-460: The context of track and field sports events. These include multiday races , ultramarathons , and long-distance races in extreme conditions or measuring hundreds or thousands of miles . Beyond these, records and stand-alone achievements, rather than regular events, exist for individuals who have achieved running goals of a unique nature, such as running across or around continents (see lists of runners: America , Australia ) or running around

2356-463: The extreme demands runners place on their bodies." The impact of long-distance running on human health is generally positive. Various organs and systems in the human body are improved: bone mineral density is increased, and cholesterol is lowered. However, beyond a certain point, negative consequences might occur. Older male runners (45-55) who run more than 40 miles (64 kilometers) per week face reduced testosterone levels, although they are still in

2418-648: The final and was the last runner to finish. Cheruiyot won the silver medal at the 5000 m final of the 2007 World Championships in Osaka , Japan with a time of 14:58.50, behind Meseret Defar in 14:57.91. In early 2009 she broke the Kenyan indoor 3000 m record with a time of 8:30.53 in Birmingham , and won the World's Best 10K race in Puerto Rico . In May, she won the Great Manchester Run 10K race. Cheruiyot won

2480-466: The first International Cross Country Championships in 1903. The annual World Athletics Cross Country Championships was inaugurated in 1973 and this remains the highest level of competition for the sport. A number of continental cross country competitions are held, with championships taking place in Africa , Asia , Europe , Oceania , North America and South America . The sport has retained its status at

2604-411: The heart enable an individual to achieve a greater stroke volume . A concomitant decrease in stroke volume occurs with the initial increase in heart rate at the onset of exercise. Despite an increase in cardiac dimensions, a marathoner's aerobic capacity is confined to this capped and ever-decreasing heart rate. The amount of oxygen that blood can carry depends on blood volume , which increases during

2666-598: The king's officials who disseminated documents throughout the kingdom by running. Ancient Greece was famous for its running messengers, who were named hemerodromoi , meaning "day runners". One of the most famous running messengers is Pheidippides , who according to the legend ran from Marathon to Athens to announce the victory of the Greek over the Persians in the Battle of Marathon in 490 B.C. He collapsed and died as he delivered

2728-530: The late 19th century marginalised competitions based on the professional, gambling model. The 1896 Summer Olympics saw the birth of the modern marathon and the event led to the growth of road running competitions through annual public events such as the Boston Marathon (first held in 1897) and the Lake Biwa Marathon and Fukuoka Marathons , which were established in the 1940s. The 1970s running boom in

2790-621: The link, which may or may not be causal. Some studies find that running more than 20 miles (32 kilometers) per week yields no lower risk for all-cause mortality than non-runners, although these studies are in conflict with large studies that show longer lifespans for any increase in exercise volume. Elite-level long-distance running is associated with a three to seven times higher risk of the knee osteoarthritis later in life compared to non-runners. The effectiveness of shoe inserts has been contested. Memory foam and similar shoe inserts may be comfortable, but they can make foot muscles weaker in

2852-412: The long term. Running shoes with special features, or lack thereof in the case of minimalist designs, do not prevent injury . Rather, comfortable shoes and standard running styles are safer. Many sporting activities feature significant levels of running under prolonged periods of play, especially during ball sports like association football and rugby league . However, continuous endurance running

2914-453: The marathon, in contrast to the typically individual sport of road running. Cross-country running is the most naturalistic form of long-distance running in athletics as competitions take place on open-air courses over surfaces such as grass, woodland trails, earth , or mountains. In contrast to the relatively flat courses in track and road races, cross country usually incorporates obstacles such as muddy sections, logs, and mounds of earth. As

2976-643: The message "we won". While there are debates around the accuracy of this historical legend, whether Pheidippides ran from Marathon to Athens or between other cities, how far this was, and if he was the one to deliver the victory message, the marathon running event of 26.2 miles / 42.195 km is based on this legend. Typical long-distance track races range from 3000 metres (1.87 miles) to 10,000 metres (6.2 miles), cross country races usually cover 5 to 12 km (3 to 7 1 ⁄ 2 miles), while road races can be significantly longer, reaching 100 km (62 mi) and beyond. In collegiate cross-country races in

3038-486: The normal range. Running a marathon lowers testosterone levels by 50% in men and more than doubles cortisol levels for 24 hours. Low testosterone is thought to be a physiological adaptation to the sport, as excess muscle caused may be shed through lower testosterone, yielding a more efficient runner. Veteran, lifelong endurance athletes have been found to have more heart scarring than control groups, but replication studies and larger studies should be done to firmly establish

3100-540: The region competing in a total of 13 events. The competition set a new high for the number of nations at the World Indoor Championships: 150 countries sent teams to the championships, with a total of 374 men and 283 women athletes entered to compete. The competition mascot was an anthropomorphic caracal named Saham – the caracal is a medium-sized cat which is native to the Middle-East. The inclusion of

3162-667: The roads to 30:47 minutes. She opened the Diamond League circuit with narrow wins ahead of Meseret Defar, first in the 3000 m in Doha and then over 5000 m in Rome. Cheruiyot guaranteed her place at the Olympics by winning the 10,000 m trial in Nairobi in June. At the Olympics, she won the silver medal in the 5000 metres and a bronze at the 10,000 metres. In 2018, she won the 2018 London Marathon with

3224-530: The running surface. It may include river crossing, scrambling , snow, extremely high or low temperatures, and high altitudes. It has both competitive and non-competitive forms, the latter being for individual recreation or social experience. As a result, courses are often set in scenic locations and feature obstacles designed to give participants a sense of achievement. It bears similarities to running sections of adventure racing . A number of events, records, and achievements exist for long-distance running, outside

3286-557: The scholastic level, particularly in the United Kingdom and the United States. At the professional level, the foremost competitions come under the banner of the World Athletics Cross Country Tour . While cross country competitions are no longer held at the Olympics, having featured in the athletics programme from 1912 to 1924, it has been present as one of the events within the modern pentathlon competition since

3348-442: The skeletal muscles and liver. With low levels of glycogen stores at the onset of the marathon, premature depletion of these stores can reduce performance or even prevent the completion of the race. ATP production via aerobic pathways can further be limited by glycogen depletion. Free Fatty Acids serve as a sparing mechanism for glycogen stores. The artificial elevation of these fatty acids along with endurance training demonstrates

3410-513: The sport is linked with the game of paper chase , or hare and hounds, where a group of runners would cover long distances to chase a leading runner, who left a trail of paper to follow. The Crick Run in England in 1838 was the first recorded instance of an organised cross-country competition. The sport gained popularity in British, then American schools in the 19th century and culminated in the creation of

3472-439: The track of a main stadium. In addition to being a common recreational sport , the elite level of the sport – particularly marathon races – is one of the most popular aspects of athletics. Road racing events can be of virtually any distance, but the most common and well-known is the marathon, half marathon , and 10 km run . The sport of road running finds its roots in the activities of footmen : male servants who ran alongside

3534-647: The transportation of large amounts of blood to and from the lungs to reach all tissues. This in turn is dependent on having a high cardiac output , sufficient levels of hemoglobin in blood and an optimal vascular system to distribute blood. A 20-fold increase of local blood flow within the skeletal muscle is necessary for endurance athletes, like marathon runners, to meet their muscles' oxygen demands at maximal exercise that are up to 50 times greater than at rest. Elite long-distance runners often have larger hearts and decreased resting heart rates that enable them to achieve greater aerobic capacities. Increased dimensions of
