The 2024 Tour de France is just around the corner. The biggest cycling event on the planet has been in the center of many riders' year-long preparation. And cycling authorities will be also more than ready. That is - for riders who'd try to use any illegal techniques to make up for insufficient level heading into Grande Boucle. In a press release, UCI explains how the testing will be approached in (and during the run-in to) the grand tour.
All doping controls at the Tour de France will be targeted and performed at any time throughout the three-week race, not only at the finish line. At every stage, the yellow jersey and stage winner will be tested. This year, all samples will primarily be sent to the World Anti-Doping Agency (WADA)-accredited anti-doping laboratory in Lausanne, Switzerland.
While around 600 blood and urine samples will be collected during the race, the period prior to the Tour de France is also key to guarantee a level-playing field during the race. Therefore, the ITA will have conducted around 400 out-of-competition tests in the month leading up to the event.

At the end of the race, the ITA will make a selection of samples that will be kept for potential re-analysis over the next 10 years, and will keep monitoring athletes closely after the Tour de France based on all relevant data it will have collected before and during the race.
When it comes to the fight against technological fraud at the Tour de France, controls for the presence of any possible propulsion systems hidden in bikes will be carried out with the use of several non-intrusive tools available to the UCI such as magnetic tablets. In 2024, a new non-intrusive inspection tool will be added to the UCI's arsenal as part of the improvement of its detection programme using the latest technology. Further information on this subject will be communicated in due course after the 2024 Tour de France.
Before each of the 21 stages, a UCI Technical Commissaire will be at the team buses to check all bikes being ridden at the start of that day’s stage. These pre-stage checks will be carried out using magnetic tablets.
After each stage, checks will be carried out on bikes ridden by: the stage winner, riders wearing a leader’s jersey (yellow, green, polka dot, white), several randomly-selected riders, and any rider who gives rise to suspicion, for example following the pre-stage control, or incidents picked up by the UCI Video Commissaire.

- It would be great if the World Champion's jersey could be rotated among McNulty, Simmons, and Jorgenson. They threaded the needle perfectly. If each hadn't done exactly what he did, exactly when he did it, the race would have gone to one of the more heralded superstars. That said, how nice that this humble and hardworking guy gets his moment in the sun.
MarkFour07-11-2026 - This is a really interesting idea, which, if well prepared could even be very successful. Very little money needs to be involved for a first season and any success could lead to rapid interest from sponsors.Jumpyjohn07-11-2026
- Hmmm, you seem to have a very convenient black and white view of things. Perhaps you haven’t been around much to discover how complex problems can become over time with people who know how to control, manipulate (or worse) others so gradually or subtly that you arrive at an irresolvable situation before you realise. This is how many inconveniences get introduced to the young, naïve, passionate or “desperate”, knowing they are not armed, protected or strong enough to defend themselves once it’s too late. Why do you think omerta culture is so widespread, why do you think so many people continue to go through so many awful things in life that others can’t understand anyone getting into? Life may be far more jolly for you but you would do well to understand (or reflect more on) the real world to refrain from being so quick to criticise those in a hard spot that may have genuine reason for speaking out.Jumpyjohn07-11-2026
- Seriously do you think when somebody gets into a serious accident, the ambulance is called by the hurt person?🤦 there is always a buddy system in place for a risky job. police , firefighters etc so that if someone gets hurt, the other call that in.abstractengineer07-11-2026
- I get the point totally. We live in the snowflake society where some riders forget they are getting paid to ride and get results. When they have a few issues they try to look outside of the real issue instead of themselves. It odd so many of the team are making no complaints and getting on with their job. If you do not like what you do find another job simples. Tough love as my mum would say.paultryan200207-11-2026
- many people advise him to grow slowly and rather do giro and/or vuelta instead of tdf. but i can totally understand that he is not satisfied with taking over once pogi declines, but instead beat him in his prime. so if he goes for tdf again, i‘m all for it. let‘s hope that pogi recovers soon!Ketterechts07-11-2026
- So gracious to offer something no-one would be prepared to pay for. The Giro is not the Tour and doesn’t command the same interest or attract the same “elite” (those willing to pay to be a part of something they consider has ego boosting potential). Roadside viewing will always largely remain free for everyone outside circuits. Introduction of a symbolic entrance to mountain climbs is worthy of exploration. Asking 1-2€ isn’t going to repulse real fans (most will spend 50-100€ on their outing that day all things included) but will prevent a portion of the total knobhead thrillseekers who will join in any large gathering as long as it’s free, just because they’re attracted to crowds, without which it it difficult for them to work up their anti-social behaviour.Jumpyjohn07-11-2026
- How is radio going to help when someone went over a cliff or bridge or off the roadside into a forest unnoticed and is laying there unconscious?Jumpyjohn07-11-2026
- Yep, next we’ll be accusing F1 drivers of avoiding Le Mans.Jumpyjohn07-11-2026
- But on what is that opinion based? Are you holding him to a different standard than others? Are you saying he should do learn to like something he doesn’t Are you saying he hasn’t achieved enough Are you saying he pretends to be better than his results? It’s actually a really strange opinion to oust if you consider it objectively or rationally. Try applying it to others or yourself by asking if not EVERYONE should then be doing more? Nobody in athletics or swimming gets criticism for not expanding their repertoire when a rival or someone else does. In fact, most who move to another event get accused of running from their rival. Opinions are boring, the reasons behind them are what count.Jumpyjohn07-11-2026
