TotalEnergies manager calls for end ketones in pro cycling: "It's not good for our sport's credibility and attractivity"
Cycling
Are ketones doping or not? On paper no, but answers will vary from person to person. It is one of the largest grey areas when it comes to current pro cycling's nutrition, but some argue for their ban immediately including TotalEnergies' general manager.
“Ketones are a grey zone in cycling. It's not good for our sport's credibility and attractivity. Everyone is aware ketones are in use among several teams but nobody knows what they really are," Jean-René Bernaudeau said in an interview with Cyclingnews. "It's ironic. Teams who say they take ketones pretend they’re not enhancing performances. So why do they take them?”
Arguably, it is said that there is some sort of benefit for the use of ketones, and that over the past few years several team have taken up their use. Whilst it is not frequently discussed openly, the substance is not banned and it is not yet proven if it carries with it negative consequences in the long-term. However, members of the MPCC (the Movement for credible cycling association) do not allow their riders to take it. Over the past few years, some have commented that it is a peloton racing at 'two different speeds'.
“The UCI isn’t acting as a governing body. UCI should follow the recommendations of the MPCC. The MPCC pushed the UCI to ban Tramadol. Now it’s a great time to solve the ketones case," he adds. “Cycling has the potential to be the world's number one sport but has no real global sponsors."

The French team manager is keen that the non-use of such substances is a request of some sponsors, and that includes TotalEnergies. "The Management Board is very sensitive about ethics issues and it's great to have sponsors with strong values. They have the power to tell their team managers and riders to stop using ketones."

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 forRafionain-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
