Let me preface this by saying I'm rooting for Wiley, partially because Astro drove me to really look into her past results and I'm convinced that she's either clean or at least could be running these times clean so I 100% give her the benefit of the doubt as I do with all athletes that have very consistent results and have never tested positive.
But when it comes to epo, it's not sophisticated and it's not expensive unless you have cancer and your insurance provider is in cahoots with amgen pretending it's totally ok to pay an arm and a leg for something that anyone can get from China for a couple hundred bucks. If you want to do epo and know how to use the internet, it's there for the taking, no doubt about that.
The thing is that her results have been way too consistent in my opinion for her to be doping, especially given that she's been tested multiple times at big meets where she raced well.
As JWH was suggesting earlier, maybe one of these gals medals in another sport altogether, such as triathlon. I can't imagine Valby swimming very well, same for Tuohy she's so tiny. Wiley has been a multi-sport star athlete her whole life, so maybe she's already a decent swimmer or could pick it up. She'd be a monster on the bike. But yeah of course I don't actually see her transitioning to tri given her potential in the 1500 and 5000, the latter of which I think may be her best event by 2028.
