that feels a bit tinfoil hat thesedays tbh, for one there'd have to be a failed test in the system, which anyone who has seen it could leak at any moment, plus why would the UCI be doing any riders any favours , surely theyd want to show theyre willing to punish anyone, as it sends a more powerful message that it doesnt matter who you are we will get you, and that their systems to catch people work.
I feel its either a serious medical issue and we hope that its not, or he has just lost his motiviation for it and the demands procycling places on him vs his personal life, which I think is the most likely.
like I actually think he was almost certainly going into his final year this year anyway, and then when youve made that decision, whats actually keeping you in the mix this year as he's not going to win TdF, he's already won the giro/vuelta, wasnt going for the world championships, what is there left to do except be a good climber for the team, and alot of pro cyclists are saying the peloton feels alot sketchier to ride in safely, he's seen first hand with his team mates your life can change in an instant with a crash. plus you get the impression Visma do push their riders alot harder so that its not so enjoyable
and it might not be Yates himself, when you realise as a pro cyclist you spend 2/3rds of the year away from your family, and you are missing out being there for your family, its quite hard. I saw Lizzie D remarking about her retirement that she was just finding being away from her family, her kids whilst theyre growing up, put alot of pressure/emotional stress on her that being a pro cyclist wasnt filling the gap anymore and almost felt selfish, when again she felt she'd achieved all that she could in the sport results wise. and the mojo has gone, you want to spend more time with your family give back to them whilst you still can and recognise the sacrifices they made to support your career.
