Twins Jake & Zane have nearly identical PRs, so doesn't Zane's bust prove either 1) EPO doesn't work or 2) Jake is dirty too?

I am going with option 2. Also because they are good buddies and moved to Kenya to train and live together. Unthinkable that one of them is clean but not the other one.

* I run faster because I believe arena management add pure oxygen.

* I run faster because I believe modern tracks and shoes some how create energy.

* I run faster because I take the same drugs Thoroughbred horses took in 1970's.

Truth: You don't run faster.

I wonder if T&F coaches have given up attempting to produce sub-1:42/sub-1:55 male & female 800m athletes.

Wejo and Rojo are identical twins. I don’t believe that either of them are/were dopers, yet they didn’t have equal running careers.

Are you joking?

Wejo doped and Rojo didn’t.

Not that many cases of twins training together and not being fairly equal. Wejo I believe made most his gains when Rojo had retired.

Caffeine isn’t on the banned list anymore, and even when it was, wejo wouldn’t have been taking it in doses anywhere near the limit.

It genuinely does not prove anything. Zane is guilty. His brother may or may not be. That is all. This is not a direct indictment of Jake Robertson. Zane Robertson was busted.

identical twins rojo and wejo have radically different PR's and neither one is good enough to be a likely doper.

I bet you anything rojo can do a pullup

They don't train together and even lived in different countries for a while.

Ooof.

Fixed now, but I had Jake's 5000m off....their numbers are incredibly close through the distances. If one was doping and one wasn't, wouldn't one have at least a couple of events that are way faster, one? All?

Either they both doped or they both didn't or EPO doesn't work. Or finally, perhaps he only doped at the end for a last final grasp at a pb?

Zane only did EPO once. So I think it's hard to make a legitimate comparison.

One of them should have doped through the roof and the other stayed clean. Then put the location of the clean one on all the whereabouts forms. After each year switch roles.

It's also very likely that Zane only began doping in the last few years - out of desperation, after a string of injuries.

Maybe he saw one too many guys getting away with it, and maybe someone gave him EPO during a moment of weakness, and rather than thinking long term, he thought "well, it's a long way back from here."

But who knows, maybe both were indoctrinated into the doping culture in Kenya fairly early on. It wouldn't be difficult, given that they were 16 went they arrived, and likely very impressionable.

Identical twins often don't have the same PBs. My identical twin was better than me, eventhough I trained better. The doping one could concievably have needed to dope to keep up with his twin, with his twin being clean.

That said, they are both probably doping because they were living and training together and sharing, likely similar personalities (personality is more getetically determined than one thinks), meaning they are likely to have the same personal propensity to want to dope given they are in the same environment. That's the bigger red flag than the PBs being similar.

They haven't been living and training together. They've been living and training in different countries for the better part of 10 years.

It's not clear Zane was doping when he set (any of) those PRs. He may have started doping at the point when he felt catching up to his old PRs would be impossible. Doping to stay in the game, as it were. People say Asbel Kiprop did that, for example.

Imbecile doping apologists say that about Kiprop, the only guy since El Full Throttle to run 3:26.

The problem with this argument is timeline. It’s impossible to say how long Zane had been taking EPO for. It may have been for many years and he’s managed to evade getting caught or it might be very recent. E.g got overly frustrated with all the athletes taking EPO and decided to join the dark side also. All of their best times were set in the order of 6+ years ago so if it was a recent transgression then their similar times makes perfect sense.

Robertson's appeared to do everything together and nearly the same. This positive test essentially implicates the twin too. They train in an area notorious for epo use and distribution. In fact, many runners go to Kenya simply for easy access to dope and discretion/anonymity in doping.
