A half-marathon is 21.0975 kilometers, or 13.1 miles.
Marathon running is a very popular international long-distance running competition, the distance of 26 miles and 385 yards, equivalent to 42.195 kilometers (also said 42.193 kilometers). Sub full marathon, half marathon and four points marathon three. The full marathon is the most popular, and general references to the marathon refer to the full marathon.
The half-marathon is equivalent to half the distance of a full marathon, so it is more suitable for the majority of people to participate in, because not everyone can run a full marathon, the half-marathon participation will be a little higher. The half-marathon is currently the fastest growing international running program in terms of audience. The length of the half marathon is challenging and not as demanding as a full marathon.
Preparation for running a half-marathon:
1, know your ability. Before you consider training for a half-marathon, running coaches recommend that you must be able to run 16 to 24 kilometers in a row for a week. If you're just starting out and haven't built up the ability to run this mileage, you'll have to wait until you have enough endurance to actually sign up for the race.
2. Start early. Half-marathon training can take months, so choose to enter a race that is not held in the near future to allow time for adequate preparation. If you're a beginner runner, plan to train for 20 weeks before the race. If you're an intermediate runner, give yourself 16 weeks. If you're an advanced runner, train for 12 weeks.
How long does it take to finish a half-marathon:
The maximum time for a half-marathon is just about 3 hours. If it's an amateur runner's first attempt at a marathon, it's perfectly fine to not think about the time or how high a goal you're setting for yourself. Just think about the feeling of trying a marathon and completing a challenge to yourself will do, if you go to the race with this mindset, you may receive unexpected results.
The marathon is a long-distance running sport that tests endurance. The required length is now 42 kilometers and 195 meters or 26 miles and 385 yards. More than 800 marathons are held around the world each year, and the larger events usually have tens of thousands of participants, mostly for fitness and recreational purposes
Marathon was originally a place name in Greece. It is 30 kilometers northeast of Athens. Its name is derived from the Phoenician word marathus, meaning "aniseed", because of the many aniseed trees that grew here in ancient times. The marathon, a sport, is named after it. It was not until 1920 that 42.195 kilometers became the official marathon distance.
The sport of marathon and the legend are inseparable, while the history of the marathon is also debated. The standard length of the marathon was officially established by the International Association of Athletics Federations (IAAF) in 1921 as 42 kilometers and 195 meters or 26 miles and 385 yards. Because the marathon is run on roads, the course conditions are different, and therefore there was a long period of time when there was no "World Record" but only a "World's Best" (or "World's Best Performance"). For a long time, there was no "world record", but only the "world's best time" (or "best time") as a runner's record. It was not until 2004 that the IAAF officially adopted the world record for the marathon, leaving behind the era of world best times.
Rules:
A runner's physical condition must be recognized by the race's medical body before he or she can participate in the race.
The marathon starts and finishes on an athletic field, and the vast majority of the run takes place on the highway, usually on a turnaround or loop route, either a round trip that starts and finishes in the same place or a one-way route that does not start and finish in the same place.
Milestones, drink stations and signposts are provided along the route. The race route should be a flat thoroughfare, avoiding crossing railroads and downtown areas. Drinking stations will be set up every 5 kilometers and time will be reported. Water points will be set up between two drinking stations.
Sports appeal:
One of the charms of the marathon is the openness of the race course. Other sports, as long as it can be used for competition, is either a piece of déjà vu, or a commonplace circle, while the marathon site is mostly selected from the city roads, for the participants, every step and every section is a different landscape.
The second charm of the marathon is the inclusion of participants. Other sports, only equal players can compete on the same field, amateurs are almost impossible to pk with professional athletes, while the marathon is different, no matter the professional athletes or amateurs, everyone can squeeze together to race.
There are obviously more than two attractions to the marathon, but it is undeniable that it is the two reasons of openness and inclusiveness that make the marathon bring more joy to people.
Runner requirements:
Physical conditions:
(a) Being undersized and underweight is not a disadvantage.
Marathon runners are generally of somewhat lower stature than runners in other competitive events.
(ii) The chest index should be large.
Bust index = (bust/height)*100%.
A large bust index means that the heart and lungs located in the chest cavity are very well developed, so it can be assumed that being born with a large bust index is one of the natural conditions that make you fit to be a marathon runner in terms of stature.
(3) Superb respiratory circulatory system.
Height, weight, and chest index are cosmetic features, but the more important aspect of a marathon runner's fitness is the respiratory-circulatory system, i.e., the functioning of the lungs and heart.
(d) The lung capacity to body weight ratio should be large.
Lung capacity to body weight ratio index = (lung capacity/body weight)*100%, and those with a naturally high lung capacity to body weight ratio index are suitable for long-distance running programs. This conclusion also holds true for a runner's suitability to run a marathon.
About lung capacity, the amount of air the body takes in and out of the lungs when quiet is about 400ml (one breath), on top of which it can inhale hard and hard to take in about 1700ml more (a preparatory inhalation), and after exhaling it can be exhaled even further to 1600ml (a preparatory exhalation). Lung capacity is the sum of these items,
Lung capacity = one breath + preparatory inhalation + preparatory exhalation.
Lung capacity is not a direct indication of respiratory function, but it is advantageous for athletes to have a large lung capacity. The average adult man has a lung capacity of 3000-4000ml, and the adult woman 2000-3000ml.
The lung capacity of track and field athletes is particularly high for throwers, with some exceeding 6000 ml.
(v) Strong stomach and liver.
In the marathon training and competition to consume a lot of energy, in order to replenish energy need to have a good function of digesting food, strong stomach and intestines is very favorable. Among the nutrients that people absorb. Sugar (carbohydrates) is broken down from glucose into glycogen and stored in the liver and muscles in all parts of the body, during exercise first consume energy within the muscles, followed by glycogen stored in the liver will be given through the blood to replenish.
For marathon runners, the ability to store and replenish energy is extremely important. The strengths and weaknesses of the gut may be innate, but the ability to store and replenish energy can be improved through training.
Basic ability:
Marathon running can be considered the ultimate goal and the other side of the river for aspiring distance runners. There are many unknown possibilities there and it is possible to imagine the joy of accomplishing one's ambitions as an athlete.
But for young athletes and athletes without systematic training, marathon running is a very tough race, so long-distance runners in the marathon, must be systematically trained, have the ability to run long distance (speed and durability), and in the adjustment of the physical and mental state to participate in the race, and should not be just a determination or a vision of the marathon to go to the race. You should not go to a race just because you are determined or have a vision of running a marathon. Runners who go to the race without adequate preparation may be disappointed or have a wrong perception of marathon running due to the fact that they have shattered their own dreams.
Mental strength:
The most important thing to be a good runner, no matter what the sport is, is to have the endurance to be able to withstand all kinds of mental and physical pains and the self-control to be able to control oneself, and to always show fresh enthusiasm for competition and keep the emotion of constantly striving towards one's ultimate goal.
But it is rare for a person to be born with that kind of high spirit, and it is through the athlete's own experience, or through the influence of teachers, coaches, old-timers, and movies and books, that the athlete grows spiritually and develops the character that is expected of him or her as an athlete.
Additionally, through the daily routine of training, the regularity of daily life, and the experience of competing in competitions, further mental torture develops into a confident and humble state of mind.
It has been said that "the marathon is a lonely race, a struggle against oneself". The marathon requires no athletic equipment, only the athlete's own body, and is equal in terms of competition conditions, the judges are completely fair, and the strongest always win.
Mental strength is not something that you are born with, but it is something that you gradually develop through training, as a kind of social nature later in life.
Mental strength is a big part of the marathon, and it is one of the basic conditions for becoming a good runner.
Spectator etiquette:
In the marathon, spectators can cheer for the athletes on both sides of the track, but must also pay attention to some spectator etiquette.
Can't just hand water to the athletes.
When watching the race, some spectators will pass water to the athletes out of kindness, which is strictly prohibited, because athletes can't just drink water or drinks that are not provided by the organizing committee. Instead of helping the athletes, the spectators' gesture of handing them water could lead to a foul or even a foul out of the game.
Can't just cross the line.
As with watching a race in a stadium, spectators are not allowed to just cross the line, rush onto the track or cross it.
Civilized cheering without uproar.
When athletes run past, spectators should applaud, cheer and holler, not clap backward and not make noise. Watching the process is not loud, shouting, hollering to civilized language, enthusiasm and generosity.
No balloons and kites.
Because the TV media will broadcast live during the race, and sometimes even need helicopters for aerial photography, it is strictly prohibited to hang or fly balloons and kites at the starting point and along the perimeter of the track during the race. Households along the track should not dry their clothes outdoors.
Be careful not to crowd or trample.
The marathon will be conducted accordingly traffic management, during which in addition to hold the marathon vehicle permit motor vehicles, pedestrians, non-motorized vehicles, motor vehicles are strictly prohibited to cross the race route. Spectators are strictly prohibited from crowding, trampling; strictly prohibited in the race route to occupy the road business, stalls, parking; strictly prohibited to the race route to throw objects, to keep the road clean.
Olympic marathons through the years:
The idea of a marathon in the first modern Olympics came from the French historian Michel Bréal (French: Michel Bréal). The idea was strongly supported by the founder of the modern Olympics, Coubertin. The Greek Spyridon? Louis (Σπυρ?δων "Σπ?ρο?" Λο?η?) won the first Olympic marathon in 2 hours 58 minutes and 50 seconds. The women's marathon was included in the official competition program at the 1984 Summer Olympics in Los Angeles. Joan Benoit of the United States? Joan Benoit won the race, becoming the first women's marathon champion in the modern Olympics. Her time was 2 hours, 24 minutes and 52 seconds. Since the first modern Olympics, it has been a tradition to run the men's marathon at the end of the day, with the finish in the main stadium. The 2004 Summer Olympics marathon reverted to the route of the first Olympics, from the town of Marathon to Athens, with the finish in Panathinaiko Stadium (Παναθηνα?κ? στ?διο), and scheduled the awards ceremony for the closing ceremony. The men's marathon record was 2 hours 03 minutes 23 seconds. It was set by Kenya's Wilson K. Kiprotich (Wilson Kipsang Kiprotich) at the 2013 Berlin Marathon. In the first four Olympic marathons, the distances were arbitrarily set by the organizers: in Athens in 1896, the marathon was less than 40 kilometers; in Paris in 1900, the distance was about 40 kilometers; and in St. Louis in 1904, the distance was about 41 kilometers. Louis Olympics, the distance was about 41 kilometers. Until the 1908 London Olympics, the marathon started at Windsor Castle and finished at the White City (White City) stadium. The course was 42.195 kilometers long, and all subsequent Olympic marathons have been of that length.History of the China Marathon:
The China Marathon Grand Slam also takes the spread of marathon culture as its responsibility, and will work closely with the member race units and **** the same efforts to provide better race services for the professional runners and the public runners participating in the marathon sport, and build a higher level of communication platforms for the race operators, media and sponsors.
