“I am not doing Grand Tours anymore, but I am still a bike racer" - Not even incurable cancer will stop Serghei Tvetcov competing in the peloton
Cycling
For many years Serghei Tvetcov has spent his professional career riding in the peloton and competing at a very high level. In September 2022 however, his world was rocked by a diagnosis of incurable blood cancer.
“You think you are healthy, an athlete, and you never get anything, and then the doctor tells you you have cancer,” the 34-year-old, three-time Romanian national road race champion explained in an interview Velo. “That’s a shock.”

“It was my low power numbers that revealed something was wrong,” Tvetcov explains. “I was lucky. Sometimes with cancer, you do not realize something is wrong until it is too late. Because I am an elite athlete, I could tell my body was off right away.”
In the end, doctors found it to be a rare form of blood cancer called Chronic Myelogenous Leukemia. Although it may be rare, Tvetcov isn't the only cycling name currently battling this disease, former Tour de France winner Greg Lemond also suffering the same form of cancer. “I was diagnosed with cancer in September 2022. It was a shock, not just for me but for my entire family,” recalls Tvetcov. “It’s not possible to cure chronic leukaemia, but treatment can control it. I am still on meds.”

Throughout the whole ordeal though, Tvetcov has remained steadfast in his determination to continue racing. “I am not doing grand tours anymore, but I am still a bike racer, and I am still competitive. I won the national title of Romania this year. That was a very emotional victory for me,” he explains.
“I want to do a project in gravel racing and I want to spread the word. The earlier you can check the better. It’s like a snowball effect. First you’re healthy, and then you can know if something is wrong. I want to spread the word you can do it," a message we at CyclingUpToDate wholeheartedly reiterate. “The main idea of the project is to send a message and inspire people with the same or similar diseases through cycling, both for them and their families.”

Dariusz08-11-2026 - Uwielbiam patrzeć, jak wyjeżdża na czoło peletonu i zaczyna się rzeź...
Dariusz08-11-2026 - 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
