By the time Luo Xuehuang, Yuan Liying and Jiang Yulu stopped the clock at 45.370 seconds in the women’s team sprint final, the Asian Games had become more useful than the awkward pre-Worlds scheduling exercise they appeared to be beforehand.

China winning was not unexpected. It had already established itself as one of the strongest women’s sprint programmes in the world and arrived in Izu with considerably greater depth than anything else in the regional field. The progression through the competition was more revealing: 46.672 in qualifying, 45.825 in the next round and then 45.370 when the title was decided.

Britain’s world record is 45.186, which makes any immediate China-versus-Britain comparison tempting, although the different tracks, conditions and competitive circumstances make that too simple. Shanghai will provide the comparison that matters. What Izu has already provided is a Chinese ride within 0.184 seconds of the fastest women’s team sprint ever recorded.

Earlier in the season its Hong Kong World Cup victory had come in 46.223. Whatever part track conditions played in the difference, 45.370 is too fast to be treated merely as another regional record.

The men reinforced the same point. China beat Japan in the team sprint final in 42.152, with Japan recording 42.511. In Hong Kong in April, China had qualified in 43.810 while Britain eventually won in 42.278. Those rides belong to different venues and different races, but an improvement of that scale across the same season is hard to separate from the broader progression visible in China’s sprint programme.

Kaiya Ota led individual sprint qualifying in 9.400, Li Zhiwei followed with 9.444 and Azizulhasni Awang rode 9.467. Ota subsequently won the sprint ahead of Li, with Awang taking bronze.

For Ota, 9.400 is confirmation rather than discovery. His 9.348 Asian record from March remains faster, while the 9.658 he produced at the Hong Kong World Cup clearly did not represent his ceiling. Izu showed that he can arrive at the end of a championship programme still operating close to the speed that puts him among the riders who matter internationally.

Li’s ride carries a different sort of interest. He was at 9.707 in Hong Kong; five months later he has ridden 9.444 and been part of a 42.152 team sprint. Taken with the team result, it begins to look less like one exceptional final and more like a programme finding speed across several riders.

The women’s sprint added another layer. Yuan Liying qualified fastest in 10.155, ahead of Mina Sato at 10.209 and Jiang Yulu at 10.352, before beating Sato in two rides in the final. Earlier in the week she had already won the keirin, leading a Chinese one-two with Wang Lijuan, while also riding in the 45.370 team sprint.

Izu was not the first time Yuan had beaten Sato for a major regional sprint title this year; she also defeated her at the Asian Championships.

Sato remains one of the defining riders in the women’s sprint field and Shanghai will place a much deeper group around both of them, but Yuan has now twice turned qualifying speed into a championship victory over the same opponent. Added to China’s team-sprint strength, that gives the programme something more substantial than the familiar argument about depth. Yuan is repeatedly delivering against one of the best sprint riders in the world.

Sato’s own position needs slightly more care. She spoke before the Games about managing a knee problem that had worsened during 2026, while Japan chose not to enter either Sato or Ota in the keirin. There is no basis for attributing the sprint defeat to the knee, although the decision to reduce their programmes becomes relevant with another major championship beginning less than two weeks later.

China made a very different choice with Yuan, asking her to race the team sprint, keirin and individual sprint. She won all three.

China’s pursuit progression

The team sprint times are the obvious numbers to reach for, although the men’s pursuit may ultimately change the Shanghai picture more.

China began the World Cup season with 3:53.228 in Hong Kong. At the following round in Nilai it rode 3:50.331 and then 3:50.318 in the final.

At Izu, Sun Wentao, Yang Yang, Wu Junjie and Pei Zhengyu reached 3:47.621 to break the Asian record and defeat Japan, which itself produced 3:49.005.

Denmark’s 3:39.977 world record from Konya has changed what the absolute top of the event looks like, while Britain, Australia, Italy and New Zealand carry deeper recent championship records than either Asian programme. China does not need to be placed alongside Denmark for 3:47 to matter.

Our earlier Worlds analysis had China among the programmes trying to force their way into the eight-team qualification rather than among those likely to shape where the cut falls. A progression from 3:53 to 3:50 and then 3:47 within one season makes that view much harder to maintain.

Japan’s 3:49.005 makes the same part of the qualification fight tighter again. It was almost five seconds faster than the 3:54.146 Japan recorded in Hong Kong qualifying, so losing the Asian Games final still leaves it with a far more relevant Worlds benchmark than it had in April.

Once Australia, Denmark, Italy, Britain and New Zealand are accounted for, the remaining qualification places were already going to disappear quickly. China arriving with a 3:47 and Japan with a 3:49 removes much of the comfort for the programmes beneath that first group.

The Chinese women followed a similar path, reaching 4:08.818 for another Asian record, with Japan setting a national record of 4:10.424 behind them.

At the European Championships, Germany qualified in 4:06.509, Italy in 4:07.365 and Britain in 4:07.447 before the competition developed further. China has not yet demonstrated the same level as the strongest women’s pursuit programmes, but 4:08 is close enough that another small step in Shanghai would no longer be surprising.

Across the four timed team events, China therefore leaves Izu with 45.370, 42.152, 3:47.621 and 4:08.818.

Japan’s different route through Izu

Japan’s endurance results are harder to carry into the Worlds because the field in Izu simply did not have the strength or depth of the one that will assemble in Shanghai.

Kanta Umezawa won the men’s omnium, Yumi Kajihara retained the women’s title and Japan won both Madisons, but those victories tell us relatively little about how the same riders will fare once the leading European and Oceanian endurance programmes are added. There was not enough international depth around them to draw meaningful conclusions about Worlds form from the results alone.

What Izu did give Japan was more championship racing. Its endurance riders have spent the week making tactical decisions under pressure, dealing with eliminations, point accumulation, Madison changes and the unpredictability that comes with bunch racing rather than completing another controlled training block. For riders who will be asked to do much the same thing again in Shanghai less than two weeks later, that experience has value even if the results themselves are difficult to carry across.

Awang’s week offered a more direct individual signal.

At 38, having qualified third fastest for the sprint and taken bronze, he won the keirin from Li Zhiwei. His 9.467 flying 200 showed that the speed remains, while the keirin showed why reducing his prospects to a qualifying time has never worked particularly well.

Shanghai will contain greater raw speed and more depth through the rounds, but Awang has just spent another championship solving the sort of crowded, imperfect race that usually decides the event.

Twelve days later

Before Izu, the unusual part of this calendar was straightforward enough. China and Japan were being asked to contest a major championship that mattered to their own sporting systems and then turn around almost immediately for the Worlds.

China has not approached the first half of that sequence cautiously. Its women’s team sprint came within two tenths of the world record, its men reached 42.152, the men’s pursuit has moved from 3:53 in April to 3:47 and Yuan has raced three sprint disciplines and won all three.

Japan has managed some of the same problem differently, taking Ota and Sato out of the keirin while still asking both to race deep into the sprint programme, and using the full Asian Games schedule across its endurance squad.

None of that makes Izu a smaller version of the World Championships. The fields were too different for the medal table to travel particularly well, and the tactical events become even harder to compare once the full international field is added.

The more interesting part is how little separation there now is between the evidence and the test.

Shanghai opens on 14 October, with qualifying for the men’s and women’s team pursuits and both team sprints. China therefore goes directly from producing its four most significant Asian Games stopwatch performances into a World Championship programme that begins with exactly the same four events.

There is no meaningful training block left between them: only recovery, travel, sharpening and another starting line.

If 45.370, 42.152, 3:47.621 and 4:08.818 came from a Chinese programme still moving towards its real peak, the opening day in Shanghai could look very different from the one we were anticipating a week ago. If those performances required China to reach that level for Izu, the twelve-day turnaround may be every bit as awkward as it looked when the calendar first put the two championships together.

Shanghai will answer that almost immediately.
