Shari Bossuyt ends battle against controversial positive doping result - "I simply don't have the strength or money for this"
Cycling
Shari Bossuyt tested positive for Letrozole in March of 2023. The World Champion on the track and current rider of Cayon//SRAM Racing has spent the last 11 months trying to prove her innocence, but it simply was not possible as there isn't an easy way to prove her contamination through food.
This is one of the most unique cases of reported doping in cycling, as both her and cyclocross rider Toon Aerts tested positive for the substance immediately after in the town of Flamanville, France - although racing in different disciplines of the sport. In the space of one month, both tested positive for the substance Letrozole, which is said to inhibit the production of Estrogen - and hence, in men, raise production of testosterone.

Both have received 2-year bans after lengthy battles. Bossuyt's ended yesterday as she announced on social media: “On December 4, I received the decision from the AFLD (the anti-doping agency, ed.) with a proposal for my suspension. As expected, they have proposed a two-year ban. They confirm and acknowledge the fact that the contamination was not intentional. But we cannot, as with Toon Aerts, prove the source of the contamination. For that reason, they cannot limit the punishment further."
It was acknowledged however that Bossuyt, a renowned sprinter in the peloton but also former Madison World Champion together with Lotte Kopecky on the Track, did not intentionally get the substance in her body. However the situation has a dark twist. It is very likely that both riders had contaminate milk in the area of Flamanville, but it is not possible in Europe to conduct a test because on paper the substance is banned from being fed into livestock. The financial burden of having to officially prove the situation, alongside the psychological pressure of the past year, has led her to end this journey of attempting to clean her name officially.

Hence the ban will remain until March of 2025, meaning another year off competition for the 23-year old. “I don't have the strength or the money for this," she tells. "The feeling of fighting a losing battle, the sleepless nights of constantly worrying and the financial suffering of having to spend tens of thousands of euros on an already lost cause, made me decide to leave it at that..."
However, she concludes with a clear message: “I am a 23-year-old girl who was able to turn her hobby into her profession. I am not a doping sinner and have never considered taking any. I will keep repeating this until the day comes when everything is cleared up.”
“No one seems to realize how much impact this has on someone's mental health. My Olympic dream has been destroyed and I have to walk around every day with the label of 'doping sinner'. It's almost unbearable. Fortunately, I find support from the people who really listen to me, who believe me. In the meantime, I will continue to exercise, because it does me good. I will prove that I will come back stronger!”

- Yeah, unreal.
parisbound0008-11-2026 - there needs to be space in life for pointless comments!Ketterechts08-11-2026
- That is a very lazy way of putting it but so far on this website it seems like everyone is happy to look at everything lazily, even things that annoy them intensely. All they want to do is state their feeling and position but ask most to analyse a problem or come up with solutions or improvements and you’re stunned by silence. Nobody even really knows how this all happens. It’s very simple and quick to just say the UCI did it but I bet you they didn’t, I bet you not more than 2 people were involved, more likely just 1. The UCI may be ultimately responsible but it is not their decision, this is about hierarchy, power and delegation. The fact that protest is possible also means it isn’t over and that MORE people could get involved for a thorough review which could throw up anything. It is highly likely it was a sole commissar who decided and has that power in a first round. Therein might lie the problem the UCI has to consider, is it acceptable to give so much authority to one single person when it is quite possible for them to have a natural bias or be too easily susceptible to imposed bias. Who is to say an individual in this position isn’t susceptible to collaboration with outside players with interests in the results, nations, families, teams, betting companies, etc. On the one hand we have sports where these problems have been worked on way more to reduce such problems, on the other hand we have sports with far stricter and more draconian rules not even concerning safety or obstruction that nobody really questions like false starts or stepping out of lane or zones in athletics. If cycling hastowork on itself, it would be good if protagonists (all kinds) would start doing a little more than just moaning over outcomes.Jumpyjohn08-11-2026
- Yes, so why not make comments less pointless?Jumpyjohn08-11-2026
- What a race! I didn't expect Vanthourenhout to collapse like that, and Wyseure did take the fight to Nys, but there was no doubt at the end. I also wonder what Aubin Sparfel would be capable of were he to race in the elites now. In the U23 ranks he is making good work of Giel Lejeune, who himself is among the better riders in the elites, and a top 10 contender in the big races (3rd at Kleebergcross, 8th at Berencross and 5th at Heerderstrand). In the French Cup, Sparfel is significantly better than Romain Debord (8th at Koppenbergcross and 10th at the Euros) and Rémi Lelandais (12th at Koppenbergcross and 19th at the Euros).
Rafionain-Glas08-11-2026 - There really was nothing in it. Schreiber was so much faster, and Brand was fighting to stay in the wheel in the sprint. Schreiber did move a bit, but to say she closed the door doesn't make sense because Brand couldn't enter it anyway, abd she wasn't impeded.
Rafionain-Glas08-11-2026 - He should have been allowed to go to Movistar. Right now both arent a good fit for each other and are just wasting each other's time and effortabstractengineer08-11-2026
- Thibau Nys does exactly what Iserbyt is calling for
Rafionain-Glas08-11-2026 - i did not see it. was the relegation justified or an overly hard decision? and don‘t cross riders deviate from straight lines all the time? bumping into each others when they cut corners, etc … why being more strict with the rules on the finish sprint?Ketterechts08-11-2026
- seems like we are advertising the website with pointless comments…Ketterechts08-11-2026
