Asahi Kasei Corporate Team Files Petition Asking for Reversal of Koki Ikeda's Provisional ABP Suspension


On Nov. 2 the Asahi Kasei corporate team issued a statement denying the allegations of doping regulation violations issued a day earlier by the Athletics Integrity Unit (AIU) in its announcement of the provisional suspension of team member Koki Ikeda, 26, the silver medalist in the men's 20 km race walk at the 2021 Tokyo Olympics and 2022 Oregon World Championships. Team management filed a petition with the AIU asking for the provisional suspension to be reversed and stated that it would "assert and prove to the AIU that no rules whatsoever had been violated."

The AIU claims that Ikeda's biological passport, which collects detailed blood data over time and allows for monitoring of changes, contained suspicious readings that suggested use of a prohibited method. Asahi Kasei management said that after holding a hearing with Ikeda and consulting with experts in the field, they "believe no rules have been violated" and said they would "work diligently to prove Ikeda's innocence."

Ikeda also issued comments expressing his confusion, saying, "I'm now in the situation where I may not be able to compete due to allegations of things of which I have no memory at all. It's extremely frustrating and I don't know what to do. Since getting official notification from the AIU on June 28 I've had help from many medical professionals, officials within athletics, and other experts, and have presented evidence showing my innocence. We will keep working hard to make sure the truth is known and that there is a fair judgment."

Ikeda was 6th at the 2019 Doha World Championships while still a student at Toyo University and went on to win silver at the 2021 Tokyo Olympics, the best-ever placing by a Japanese athlete in his event. He went on to repeat a year later with another silver in Oregon. He was 7th at the Paris Olympics in August. He is the cousin of TV personality Miyu Ikeda, also known as Michoppa.

According to Asahi Kasei management, on June 28 the AIU notified Ikeda that blood tests taken between June and August, 2023 suggested possible blood doping, and that if he had any explanation it should be submitted by a specified deadline. He submitted a statement to them on July 24. On Nov. 1 the AIU publicly announced his provisional suspension.

Asahi Kasei explained, "No prohibited substances listed in the World Anti-Doping Agency's International Standard Prohibited List have been detected in any of Ikeda's samples. In order to detect blood doping, the AIU regularly conducts blood tests on targeted international-caliber athletes like Ikeda to measure levels of hemoglobin and other blood components. If there are changes from past levels detected that exceed limits set for an individual athlete's profile and these changes are believed to be indicative of use of a prohibited substance or method, the athlete will be notified and asked to give an explanation of how the changes were not a result of a violation of the rules. The current case involves blood samples taken from Ikeda in June last year which showed that his hemoglobin and other parameters had exceeded particular limits."

The Asahi Kasei statement went on to say, "After receiving the notification in June this year, Ikeda began assembling a portfolio of information about his lifestyle, training and physical condition as well as his blood test data kept by the Japan Institute of Sports Sciences, and asked for help from sports medicine professionals and medical research experts with extensive knowledge within the field of anti-doping research. The opinion of these experts was that the fluctuations in the readings of Ikeda's hemoglobin and other levels were not a result of blood doping, but were due to intravascular hemolysis and gastrointestinal bleeding due to his training, living environment and physical health and the side effects of medication prescribed at the time. A document explaining this was submitted to the AIU."

Translator's note: Just 5 days before the AIU announced Ikeda's provisional suspension, his Asahi Kasei teammate Masatora Kawano broke the world record in the 35 km race walk at the National Race Walking Championships on Oct. 27.

Osaka Marathon Preview

The Osaka Marathon is Sunday, one of Japan's biggest mass-participation races and the next stop on the calendar for its elite marathoners hoping to qualify for the L.A. Olympics marathon trials in the fall of 2027. Last year it snowed mid-race, but this year is looking warmer than ideal given the season, with sunny skies, almost no wind, and temps forecast to be 11˚ at the start and rising to 19˚ by the time the winners are finishing. NHK is broadcasting Osaka with a heavy emphasis on the men's race, and if you've got a VPN you should be able to watch it from overseas. There's also official streaming on Youtube starting at 8:30 a.m. local time, although it doesn't look like it's the same as what NHK will be showing. Given Osaka's history at the elite level as the continuation of the men-only Lake Biwa Mainichi Marathon, the women's field is small relative to the men's, just enough to tick World Athletics' label requirements and with almost no do...

Arao Becomes 1st Man in 40 Years to Score Back-to-Back Ome Road Race Wins

30 km is an under-appreciated distance, and both of Japan's big races at that distance happened Sunday. At the Ome Road Race in western Tokyo's mountains, Sydney Marathon 6th-placer Masato Arao (ND Software) became the first man since the great Kunimitsu Ito in 1985-1986 to win back-to-back years. Arao, who finished 39th of 40 on his leg at the New Year Ekiden last month, stayed in the pack through 20 km before going on the attack, putting over a minute on New Year Ekiden Sixth Stage CR breaker Yudai Shimazu (GMO). Sub-1:31 winning times are rare on the tough and hilly Ome course, but Arao's 1:30:54 almost equaled his 1:30:50 from last year, making him the first Japanese man ever to do it twice and second only to CR holder Ezekiel Cheboitibin . Next up Arao races the Tokyo Marathon, where he is targeting sub-2:06. Shimazu was 2nd in 1:31:58 and Yuta Nakayama (JR Higashi Nihon) 3rd in 1:32:07. Cheboitibin was only 9th, running almost 8 minutes off his CR in 1:36:42. Shi...

Nagoya Women's Marathon Elite Field

Last year's top 3 Sheila Chepkirui , Sayaka Sato and Eunice Chebichii Chumba are back for this year's Nagoya Women's Marathon on Mar. 8, but things are being set up more for it to be a race between Chepkirui, 2:17:49 in Berlin 2023, Aynalem Desta , 2:17:37 in Amsterdam last fall, and Japanese NR holder Honami Maeda , 2:18:59 at the Osaka International Women's Marathon in 2024. Aynalem has the freshest sub-2:20 of the 3, with neither Chepkirui nor Maeda having done it in 2 years. Maeda's only recent result is a 1:10:07 from Houston last month, but when she ran her NR she didn't have any kind of tuneup race to indicate her fitness so it's probably best not to read too much into that. If it goes out as a 2:18 race those are the only 3 who can probably hang with it. If it turns out to be more of a 2:20 race like when Chepkirui won in 2:20:40 last year then there's a group of 7 at the 2:20-2:22 level who will be in the picture, including Chumba, Selly Chep...
