Kipyegon has been absolutely money for years. She never has a bad race. Other athletes burst out with wicked times then absolutely crap the bed. Invincible to also rans. That's a big mark for me that Faith is clean. She was insane as a junior, insane early career, and insane now. Nearly always perfect tactically too. When she runs fast times it's cause she's well paced, even, and often following someone else letting them do the work. None of this going out crazy from the gun solo front running stuff.
I think I'd be more suspicious of someone who never has bad days. Also how long can someone legitimately hold their peak racing form? Can she hold 3:51 form for a month? Does she even need to?
