Ding Yi was in front of the three people. Originally, Zhang Qian was in the back of him, but Wang Zhijun then changed positions with him.

"I have to be the one behind him. We can't compare to the veterans. For the same period, I'll beat him up first."

Ding Yi turned his head and said, "Then you have to hurry up and don't eat dust from me."

Ding Yi ran, and Wang Zhijun made preparations. He stared at Ding Yi, and when he rushed over the front a hundred meters and turned around the sign, he rushed to chase him.

In fact, if two people run a 400-meter obstacle, it is not easy to catch up if they stagger a obstacle group, especially at the beginning, after all, they are staggered by 100 meters, even if it is fast, it will take ten seconds to get up and down.

Ding Yi finished chasing and stabbing the flag one hundred times before, and then walked around the flag, which was three steps. It started from here that his speed slowed down.

The three-step piles have five straight 30 cm thick and thirty centimeters that are one punch above the ground. They are arranged in a side w and thirty centimeters and pass through three points in three steps. This may require a certain sprint speed, otherwise you will not be able to step on the top of the pile.

Ding Yi was quite smooth. In addition, the veteran in front had already recorded the rough stride. After passing three steps, he reached a trench with a length, width and depth of 2 meters. The previous time he passed the trench, he jumped directly. This was not unbalanced and difficult for an adult man. Most adult men could jump over two meters in a standing long jump, let alone crossing it.

Jump over the trench and sprint forward a little further and reach the low wall.

The low wall is 2 meters wide and not high, just a little over one meter, with a thickness of one shoe. There is also a wall hole on the left wall of the low wall that is 50 cm wide, 40 cm high, and 60 cm above the ground.

There are two ways to pass through the wall hole. One is to cross the wall, and the other is to cross one leg first and pass through the wall hole.

When he first rushed over the low wall, Wang Zhijun had already chased after him. When he arrived at the three-step pile, he jumped over the three-step pile, and directly crossed the trench, and headed towards the low wall.

At the beginning, he did not think about crossing the wall directly, but used a different method from Ding Yi, and stepped directly through the hole in the wall, and he had to crawl over as soon as he bent his waist. However, because it was the first time, he was not sure and his head was not low enough, so he directly hit his head.

"I'll go, it hurts so much!"

Wang Zhijun shouted, bent his waist down and passed the hole in the wall.

In fact, the most correct order is to rush through the wall hole when you come back. However, in general, the 400-meter obstacle is not as strict as the requirement and must be completed in the corresponding order. The two passes can be replaced.

However, the order can be changed, but the same method cannot be used both times.

For example, when we passed by, we chose to pass through the wall hole, and when we came back, we would pass by the wall as we were. First, we chose to pass through the wall hole when we came back.

The same is true for the cloud ladder, which is completed in two ways, and it is also flew back and forth. One is to pass the cloud ladder with both hands, and the other is to run directly from the cloud ladder.

Because Wang Zhijun hit his head in the wall hole, he naturally extended the distance to chase Ding Yi. However, he was smart. He went through the wall hole at the beginning, completed the slow one first, and then chasing him later, and then he was relaxed.

Of course, this was not the first thing Wang Zhijun thought of. He also saw that the veterans in front did this. As long as they chased the people in front and those who were closer, they chose to pass through the holes in the wall first. He followed suit.

Ding Yi did not dare to look back, and he did not expect that Wang Zhijun would chase him so quickly. In order not to catch up with him, he could only speed up and rushed to the next obstacle and jumped to the high board.

There are three high plate jumping platforms. The highest one is 1 meter 8, the length is 2 meters, the width is only 50 cm, the thickness is 5-8 cm, the height in the middle of the row is 1.5 meters, the length and width are 1 meter each. The lowest one is length, the width and height are 1 meter each. The three jumping platforms are 1 meter apart.

When jumping over the high-end shift, just be careful and pay attention to your feet. There is still no problem. It is easy to complete, but the speed is nothing more than the speed.

In order to increase his speed, Ding Yi was not sure when he was on the last low jump, so he stepped on the air and jumped in front, almost twisting his foot.

He paused here, turned his head and looked back, and was about to continue rushing forward quickly.

At this moment, even the last Zhang Qian had already chased the low wall, only one obstacle away from Wang Zhijun.

After passing the high-board jumping platform, it is a single-plank bridge.

The single-plank bridge should be considered to be a difficult obstacle to pass. It is 5 meters long, 1 meter 3 high, and 20 cm in diameter. The bridge plane that lands at the top is only 10 cm in width. The inclined board that hits the single-plank bridge is 2 meters long and 20 cm wide.

When you passed by, you rushed over the bridge, and when you returned, you passed by the spacing piles under the bridge.

The order this time cannot be changed, because the slope only has one side, and only when you come over can you climb the bridge along the slope.

Ding Yi ran the 400-meter obstacle for the first time because he would not make any mistakes again. Unexpectedly, when he rushed forward, he did not do his balance well. He just ran two steps and did not step on the right position and jumped down directly.

When the company commander saw it, he shouted to him: "Next time, I'll be careful. I'll run to the finish line. Pay attention to the bridge. Just keep a close eye on the bridgehead and run in a straight line."

Company Commander Qi Hai was also tolerant of Ding Yi for the first time, and he didn't expect Ding Yi to make mistakes once and never show up for the first time.

In fact, when he ran here, Ding Yi had already started to breathe heavily. Although the distance was not long, he ran at the speed of the sprint, but it was not better than five kilometers at all.

After crossing the single-plank bridge, the next obstacle is the high wall. This requires skills and even more sprint speed. If the speed cannot be increased, a lot of time will definitely be wasted here.

The high walls are made of wooden boards with width, height and thickness of 20 cm. To be honest, they are not high and cannot stop an adult man.

However, if the time to pass the high wall in a 400-meter obstacle exceeds three seconds, it is a very unqualified result, which requires running and jumping the bridge.

Ding Yi accelerated his speed and passed the high wall in just two moves. However, after he landed on the ground, his legs were a bit abnormal in his first two steps.

This is a definition that when the stronger he is, the error occurred. His knee hit the high wall. It hurts a lot, and he almost fell down as soon as he lands.

At this moment, he never dared to look back at where Wang Zhaojun was chasing him. He knew very well that he had made two or three mistakes. If he stopped rushing the time, Wang Zhijun behind him would definitely catch up with him.

He raised his foot and rushed directly towards the next low pile net that would delay speed!
