There is no track and field field for a lap of 800 meters

There are very few track and field fields with a meter lap, and the standard track and field field is a 400-meter lap; There are also non-standard 200m, 300m, or 800m ones.

2. The standard track and field field is a semicircular 400m runway. When the radius of the inner curve is 36m, the length of the two curves is long, and the radius of the inland sea course is 240m and the length of the two straights is 160m. The inner edge of the runway is built"Protrusions", the width is not less than 5cm, the height is one, if the protrusion is not built, the 5cm wide mark line should be drawn.

The track and field field with a circumference of 800 meters covers a large area, the international standard is 400 meters in circumference, and a standard football field is placed in the middle of the field!

The venues are built according to professional runways, only 400 meters, if 800 meters are built, it will require a considerable sports venue, and the middle configuration of the venue is also a problem.

The standard playground is 400 meters on the first lap; 2nd Lap Meter; 3rd Lap Meter; Fourth Lap Meter; 5th lap of rice; Sixth lap of rice; 7th lap of rice; Eighth lap of rice.

The stadium refers to an outdoor track and field field with a 400-meter track (including a football field in the center), a fixed track and teeth, more than 6 tracks, and fixed stands. The stadium is divided into more than 25,000 people in Class A, 15,000-25,000 people in Class B, 5,000-15,000 people in Class C, and less than 5,000 people in Class D.

Precautions. 1. When entering the stadium of the sports center, please be sure to take care of the venue and facilities, and please do not move or debug the equipment and facilities in the stadium at will.

2. Maintain environmental hygiene, please do not smoke, spit, or spit gum in the venue. Please put fruit peels, paper scraps, drink bottles and other sundries in the trash, consciously abide by public morality, and take care of public property.

3. Please do not chase and fight in the venue, and consciously maintain public order. Persons with pets and intoxication are not allowed to enter.

4. Please take good care of your belongings when entering the event.

The size of the lap of the marked track and field field is 400 meters. The field is mainly used for sports training, sports activities, sports competitions, etc., and is a venue for track and field sports. There are two types of track and field fields: standard track and field field and non-standard track and field field.

The interior of the track and field has a circular track consisting of two curves and two straights, and each non-grinding area is the same. The track and field is a semi-circular track, and when the radius of its inner curve is 36m, the length of the two curves is and the length of the two straights is. If the radius of the inside curve is 240m, the length of the two curves is 240m, and the length of the straight is 160m.

The straight white line on the track and field is the finish line and the starting line for the 100 and 110 meters. The white stepped lines are the starting lines for the 200 and 400 meters. The Zhengzhi white arc is the 1000m, 1500m and 3000m and 3000m steeplechase.

The yellow line with the hook is the 4x100m relay and the blue line is the 4x100m starting line. The green arc is the lane grabbing line.

The IAAF Handbook stipulates that the standard semi-circular track and field track is 400 meters long and consists of two straights and two curves. At present, international and domestic track and field competitions usually use the following rules and regulations.

a) An athletic field with a radius of 36 meters along the inner protrusion.

The calculated radius of one lane is meters, the length of the line of one curve of one lane is meters, and the length of the calculated line of two curves is meters. The length of one straight section is meters, the length of two straight sections is meters, and the length of the calculation line is 400 meters. Such as Beijing Workers Stadium, Liaoning Anshan Stadium, Shanghai Hunan Stadium, etc.

2) Athletics field with a design radius of meters along the inner protrusion.

The calculated radius of one lane is meters, the length of one curve is 120 meters, and the length of two curves is 240 meters. One straight section is 80 meters, two straight sections are 160 meters long, and the length of one lane and one circle calculation line is 400 meters. Such as the track and field field of the Beijing National Olympic Sports Center, the track and field field of the Shenyang Sports Center, and the track and field field of the 24th Olympic Games in Seoul, South Korea.

3) Athletic field with a design radius of meters along the inner protrusion.

The calculated radius of a lane is meters, the calculated line length of a curve is meters, and the length of the calculated line of two curves is meters. One straight section is meters, two straight sections are meters long, and the length of the calculated line is 400 meters. Such as Dalian Stadium, Guangzhou Olympic Athletic Stadium, Changsha ** Stadium, 23rd Olympic Games Los Angeles Athletic Stadium, etc.

4) The width of the track for the race.

The track is m to m (eight lanes) or m to m (six lanes) wide, each lane is m wide (including the right lane separation Hongtong line), the width of the lane line is 5 cm, and all lanes should be the same width. Except for the grass runway, the inner side of the runway should be demarcated by a protrusion made of suitable materials, with a height of about 5 cm and a minimum width of 5 cm; If drainage can be done, the protrusion can be up to centimeters, but not exceeded; If there is no protrusion, a 5 cm wide marker line should be drawn.

v) Record-breaking runways.

The rules stipulate that the radius of the outer track of a record-breaking runway must not exceed 50 meters. Unless the arc is formed by the larger of the two radii of the curved section of the site, the curve at 180° does not exceed 60°

vi) The inclination of the runway.

The maximum right-left inclination of the runway shall not exceed one hundredth (1:100), the total inclination of the running direction shall not exceed one thousandth (1:1000), and the lateral inclination of the new runway shall be inclined inward (low inside and high outside).

7) Obstacle course.

The obstacle course can be on the inside of the runway (radius 36 meters, meters) or the outside of the runway (radius meters, 36 50 meters), and it is best to be located on the outside of the runway outer protrusion, but it covers a large area.

8) The longitudinal axis of the athletic field.

The longitudinal axis (i.e., the middle line) of the track and field field should be in the north-south direction, avoiding the dominant wind direction, and the angle between it and the meridian should not be greater than 5 10 degrees, and there should be a certain buffer area in front of the end line.

<> 400 meters. The "Handbook of the National Athletics Federation" stipulates that the total length of the standard semi-circular track and field track is 400 meters, and the spring is composed of two straights and two curves, with a semi-pure lifting and laughing diameter of meters, 8 lanes, and a width of the road, and the dividing line of the outermost circle.

Long meters, the real running line is long meters. The straights should run in a north-south direction to avoid the dazzling effects of the sun when the sun is low. There should be 8 runways in the corners, each in meters wide and 10 runways in the straights.

The safety area on the inside of the runway shall not be less than 1 meter, and the safety area on the outside should be 1 meter, the starting area shall be at least 3 meters, the sprint buffer section shall be at least 17 meters, the maximum inclination of the left and right sides of the runway shall not exceed 1:1000, and the downward inclination in the direction of running shall not exceed 1:1000.

The IAAF Handbook stipulates that the total length of the standard semi-circular track and field track is 400 meters, which means that the track and field track is 400 meters in one lap. The track and field track is an oval design, consisting of two straights and two curves, and a standard track and field track is generally set up with 8-10 lanes, each lane is meters wide.

Under normal circumstances, one lap of the track and field track is 400 meters, and when the radius of the inner curve of the standard track and field track is 36 m, the radius of the two curves is long, the radius of the two straight courses is 240 meters, and the length of the two straights is 160 meters.

At the same time, a standard track and field field is generally composed of three parts: the outfield, the midfield and the old base field of the inner tour, the track is distributed in the midfield, and the radius of its innermost circle is 36 meters. Generally, there are 8-10 lanes, and the width of each lane is meters. The track is covered with a plastic surface layer to increase friction and thus improve the level of competition of athletes.

The reason why the track and field track is oval

Many people are curious about why the design of the track and field track is oval instead of rectangular, the main reason is that the design of the track and field track is fully considering the exercise habits of the human body, and the oval track can better save the physical strength of athletes. Whereas, if it is rectangular, the athlete exerts more stamina when turning.

The size of the basketball court is 28 meters long, 15 meters wide, and the circumference is (28 + 15) 2 = 86 meters, 800 86 =, about running laps.

Summary. Hello, glad to answer for you. For a 250-meter lap, the three laps are 750 meters, close to 800, and for 50 meters, you can run a fifth of the playground to complete the 800 meters, so you only need to run three laps plus a fifth of a lap.

Hello, very high wear pants and happy for the blind trace of your answer. A lap of 250 meters, three laps is 750 meters, close to 800, and there are 50 meters, and then run one-fifth of the playground to complete 800 meters, so you only need to run three laps plus one-fifth of a lap to be a pure ant.

Of course, many playgrounds will be marked at 50 meters and 100 meters of the circle of Changzhao Ju Hu, and you can look at the standard under your feet. Hope the above helps
