2005 was a year of great changes for track and field competitions.

This year, the IAAF officially integrated some of the previous competitions and unified them into the IAAF World Athletics Tour. There are two main athletics competitions at different levels: the first is the IAAF Golden League and the IAAF Super Grand Prix, the second division is the IAAF Grand Prix and some regional franchise events.

Each year, the World Athletics Tour features a total of 25 top-notch athletics events, including: six Golden League, five Super Grands Prix and fourteen Grand Prix.

Athletics athletes earn points at these designated IAAF World Athletics Tour events, depending on the level of the tournament and the athlete's ranking. The Golden League and Super Grand Prix have twice as many points as the Grand Prix, and athletes can also earn extra points at certain IAAF-sanctioned regional events.

The athlete with the highest score at the end of the season on the World Athletics Tour can compete in the World Athletics Finals, which are the climax of the year's World Athletics Tour and come with a significant prize money.

Since 2010, due to the restructuring of the IAAF, these major events will be replaced by the IAAF World Challenge and the IAAF Diamond League.

But in 2005, the IAAF World Athletics Tour, which had just been launched, was still more influential.

Originally scheduled for early May, Su Zu and his entire team set off from the magic capital to Osaka, Japan, for the IAAF Grand Prix.

However, just a few days before he was about to leave, Su Zu received a special invitation. His original middle school, Yangxin Middle School, invited him to attend the inauguration ceremony of the school's new track and field field and teaching building.

Originally, according to the plans of Li Zhizhong, Zhang Pingqiu and others, he was now in the preparation period and could not attend.

But in the end, at Su Zu's insistence, Zhang Pingqiu and Yu Yaling accompanied him to quietly leave Shanghai and return to Yangxin Middle School in Wuxing County, which was lying in Ronghai.

The whole event was very short, Su Zu actually mainly attended the appearance, and then thanked the local government and the education bureaus at all levels for their support.

During this period, Yang Xiaohe, the principal who had visited Su Zu's house, and his physical education teacher Ao Dingping looked at Su Zu and sighed a lot, but they never thought that the ordinary peasant teenagers who had loosened the middle school and sent to the sports school had now grown into world-famous Olympic champions.

After the event, Su Zu did not leave immediately, but walked around the side of the track and field and ran twice.

He always remembered that afternoon when he woke up in the classroom, that gym class.

Because it is adjacent to the bank of the river, there is a vacant lot, and the original playground has been expanded several times. The 200-meter cinder track has long since disappeared, and the uneven loess and sand hard ground has been replaced by a completely new plastic playground.

The standard 400-meter track and several basketball courts in the middle of the track are brightly divided in the sunlight.

Su Zu didn't know if there would be the next person who would start from this runway, step by step on the road of sports competition, and run out of his own life. But he thought that being able to change something in advance always proved the value of his existence.

In a rural primary school in Hunan Province, a special physical education teacher formed a women's basketball team composed of left-behind children there, and led them to play a small world.

No matter how the story ends, those little people who have fought hard in the arena will never forget that experience.

After finishing the activities of the middle school in the past, Su Zu did not stay too long, and rushed back to the magic capital again without stopping.

On May 4, after a more than two-hour flight, Suzu arrived in Osaka, Japan.

The 2005 Grand Prix will start here, followed by two Grand Prix races in the United States, before heading to Europe for the Golden League and Grand Prix. At the World Athletics Championships in August.

This is the first time to participate in the track and field Grand Prix, because he has not participated in this kind of points competition before, Su Zu is now in the IAAF men's track and field athlete points rankings, still dozens of outside, among which the most points for him are the Olympic Games and last year's World Indoor Athletics Championships.

The current top few are Shahen (Qatar, 3000m steeplechase), Olsson (Sweden, triple jump), Bekele (Ethiopia, long-distance running), Alekna (Lithuania, discus), Liu Yangyu has previously taken the situation of training by competition, and the ranking is not low, currently 15th, and his old opponent Alan Johnson is currently ranked sixth.

May 7, Nagai Gymnasium, Osaka.

The stadium has almost 50,000 seats, was the venue for three matches at the 2002 World Cup and was the main venue for the 2001 East Asian Games. If nothing else, Su Zu's schedule this year also includes the East Asian Games, which will be held in Macau this year.

At 20:30 in the evening, Su Zu appeared at the scene of the gymnasium of the Yongjing Gymnasium.

Night had fallen, but the stadium was brightly lit and more than 50,000 seats were filled.

Before the race, the organizers once again put Suzu to participate in the Osaka Grand Prix, because of the performance of Suzu Yokohama All-Star Game last year, once again broke his own Asian record, and won Gatlin Morris Green and a Japanese star, and it is also very popular in Japan.

Su Zuzu competed in the men's 200 meters, which started at 20:30, and then the 100 meters in 45 minutes. The athletes who can participate in the Grand Prix are all high-level, and the number of them is small, and they are basically one-shot winners, and there are no preliminaries, rematches, etc.

The Osaka Grand Prix was held in Japan, which was far away, and many of the famous players did not attend.

For example, Powell is participating in a major tournament in China at this time, and some of the American stars such as Gatlin, Sean Crawford, and Green are sure to participate in the two Grand Prix in the United States in June, but the Osaka Grand Prix did not come. On the contrary, Scott, who was in the All-Star Game last year, was very active in participating in various competitions because he had just made a comeback.

Standing on the field, Su Zu took a look, most of them were acquaintances, like Stefan Buckland, Kim Collins, Thompson and others at last year's Olympics, plus two famous Japanese players Shingo Sueji and Nobuharu Asahara.

After the men's 200-meter race gunshot, Su Zu ran very easily, from the start has always occupied a certain advantage, after three months of winter training last year, and after the beginning of this year, the first few months of giving up the national indoor competition and the national Grand Prix, there is enough time to train. At this time, the level of performance has surpassed that of the players present.

Of course, it is not to say that the results have improved instantly, the massive increase in flexibility has allowed Su Zu to cope with such a competition more calmly, for example, he can obviously feel easier than before in the corners.

Su Zu's goal at the Osaka Grand Prix this time is also very simple, to win the men's 100m and 200m championships, of which the men's 100m can best set a new record at the Osaka Grand Prix.

The Osaka Grand Prix men's 100m record was 9.91 seconds set by Morris Green on 13 May 2000, while the 200m record was 19.87 seconds set by Frankie Fredericks on 8 May 1999.

The results of the two races were basically not too suspenseful, and in the 200m, Suzu ran a time of 19.98 seconds without any opponents at all. Again he ran into 20 seconds, but it didn't exceed his Olympic level, mainly because there was no opponent who could compete, he ran too easily, and there was a bit of slack in the back. If you really want to break Frankie Fredericks's 19.87 seconds, you still need to be stimulated by competitors of the same level.

In the 100-meter race that started at 21:15, this time Su Zu maintained a relatively high concentration, after all, the 200-meter did not want to be 100-meter, which gave the players a certain margin for error.

9.89 seconds, the same time as his last All-Star Game.

The audience and coaches on the sidelines applauded again and again, and Su Zu was able to run 9.89 seconds in the competition again, which is a very positive thing. At least it says a lot about his level and form.

But Su Zu just shook his head after running, his physical attributes were digitized, and he was able to maintain his state and level, and every time he played, he was at a high level. But without the corresponding opponent's stimulation, there is still no way to reach its own limit.

He clearly knows that during this period of training, the attribute points in all aspects have increased a lot, although after reaching such a level, the attribute points are only quantified and it is difficult to improve easily, but if there are masters to compete, he believes that he should be able to run better than now.

Standing in the middle of the track and field, Su Zu looked at the audience who were applauding him warmly and the flashing magnesium lights from time to time, and felt that if he wanted to go further, he had to point to the Oregon Grand Prix on June 4 and the Reebok Grand Prix in New York on June 11, where the real masters gathered.
