Hi everyone!!!
Since the first ''big news'' broke out today, I guess it is time to start a new thread.

So you're using "false positive" to mean that the compound wasn't actually in the sample at all? Rather than that it was present, but not due to intentional ingestion? In that case, have you ever used a GC-MS^n instrument? The meaning of the "n" is that they look not only for a compound of the exact matching mass (at fairly high resolution) that has the same chromatographic retention time, but also that they fragment the compound and look at the exact masses of the fragments. To get a false positive signal from that instrument in a triplicate assay (as required by WADA) is extremely unlikely.
[Disclosure: I'm a professional chemist with a couple of decades of work on metabolism. I didn't work with human samples or on athletic performance, but I have used the same instruments and techniques to identify and quantitate molecules in biological samples.]
Canada does. My wife's new job involves analyzing who has met the level and making recommendations as to who should be supported. Bec. would definately have hit Canada's criteria.
The support though isn't financial, it is access to resources (nutrition, sports science, mental performance, ect...). The problem that all sport federations face is usually the athletes who need those resources to be sucessful don't hit the criteria to get those resources.

A federation who doesn't, and never has understood MTB racing, and doesn't take it seriously. Track & Road rules for them.......

On a related note, I saw the announcement about USA Cycling setting up and MTB headquarters in Bentonville with money from the Waltons. Will that translate into more resources for US athletes or just marketing for NW Arkansas?
That probably depends on what they were getting when it was out of CO, so maybe something is better than nothing. I'm excited they're coming to my backyard but also bummed, cause last year when the USAC juniors were in town for the US Cup races I went from top 10 to back of the pack in our weekly short track races real quick....

Wereldbeker mountainbike toch niet naar Valkenburg in 2023
In augustus werd Valkenburg nog aangekondigd als startlocatie van de Wereldbeker mountainbike in het seizoen 2023, maar nu is de Nederlandse manche verdwenen uit de definitieve UCI-kalender. De Wereldbeker cross country gaat nu van start in het Tsjechische Nové Mĕsto Na Moravĕ. Aanvankelijk was...

Valkenburg removed from calendar, leaving an 8 round series. I would love to know the reason...I can't recall many updates about it.
😆. Just more money in Jim Miller's pockets for running more and more easily accessible camps under the pretense of development. USAC is a joke. They haven't made a significant change to operational policy, that is anything other than reactionary or an attempted money grab, for years.
Ugh, that's disappointing. I was looking forward to seeing a new venue.Wereldbeker mountainbike toch niet naar Valkenburg in 2023

I wonder how they will do the courses for the XCM. I'd have actually thought Albstadt would be a great XCM course, though I'm only guessing that the surrounding hills/trails are similar to the XCO.
Nove Mesto XCO and XCM is cool!
Only 4 XCM? I assumed each XCO would have a matching XCM race.
All 4 XCM are also going to have amateur racing with no qualification requirements. A bit late for me to plan another trip this coming year, but if that continues in '24 I see an MTB vacation in my future.
I remember in the early 90's, I raced a world cup in Michigan. They had full amateur racing, and all the pros. It was killer. Made for an incredibly fun and worthwhile weekend. I forget which day I raced on, might have been a friday or something. That's why the Norba races were cool, I raced Sport class at every one that came around my area with nothing but a signup.

That definitely confirms they won't be on the XCO course then 😜
Yes, but apparently not very well
The resources that USAC provides is mostly non-financial as LMN had stated in regards to Canada. Unfortunately USAC's philosophy is support only those who have Olympic medal potential and right now that is almost exclusively the track program, which is receiving most of the focus and $ resources right now.

This doesn't answer your question, but Britain funds cycling through the proceeds of lottery. And cycling actually gets the money, (rather than in the US where the lottery money for schools goes through many bureaucrats to buy half a box of staples for the school district)

Both. I understand your faith in the technology, but I have less faith.
Humans are still looking at interpreting the results. For example, with your experience, I'm sure you also know that it is not just Zeranol being tested for. In particular urine is tested for "downstream" (LOL) metabolites / derivatives, and used to support the possible presence of the original.
The decision to label a sample as "positive", in particular was somebody sat down somewhere and decided to go against printed advisory, and rule a "questionable" as a "positive" when it wasn't even close. That decision was100% human, not instrument, which leads to my mentioning "bias".
I have no dog in this fight, I just look at...
Negative
Negative
Negative
Negative
Hair Sample Negative (FWIW)
..and then I lose my trust in the process, and am looking for alternative explanations.
