The venue used for the competition is the standard speed skating venue. The track in the venue is closed and consists of four parts, namely two straight track and two curved track with an arc of 180 degrees. The width of the track is 5 meters, the outer perimeter is 400 meters, and the inner perimeter is between 333.1 and 333.3 meters. Among them, the two straight runways are 111.98 meters long, the radius of the outer runway is 30 meters, the radius of the inner runway is 25 meters. The dividing line on the runway is made of snow and is 10 cm wide and 5 cm high. The snow line can't be frozen to the ice, it needs to be well-built. Instead of snow, a colored rubber or piece of wood can be used for the snow line, with the finish line in red and all other lines in blue.

Second, the ice skates

The advanced speed skating blades used in the competition are made of high quality high carbon steel and light alloy, and the blade is very wear-resistant. The skates are lower and longer than the skates. The base plate and blade are the main components of the skates. In addition, the skates also include blade tube, front and back blade holder, front and back tray and other components. Thick cowhide is the main material used to make skates. The heel is made of hard material, the sole is hard leather, and the skates are fixed to the sole. The skates are longer in front and back than the skates, with the front end 8 to 9 cm longer than the tip and the back end 5 to 6 cm longer than the heel. The position of the left and right foot skates fixed to the skates is different, which is determined by the direction of the corners in the competition. The athlete's body leans to the left as he comes round the corner.

In order to adapt to the curve, the skate should be loaded with the tip of the left foot between the big toe and the second toe, the tip of the right foot should be in the big toe, no matter which foot, the end of the skate should be in the middle of the heel. Speed skating skates are different from figure skating skates and ice hockey skates. The differences of the three skates are mainly reflected in height, length, thickness, weight and other aspects. Of the three types of skates, the speed skates are in the middle of the other two, neither too high nor too low, and are the longest, thinnest and lightest of the three. To maintain a good straight skate, the blade of the speed skate is flat. Skates and skates are combined together in a complete set, specifically, the size and style of the skates depends on the size of the skates.
