Since the last Worlds, Miller-Uibo has given birth, competed in her country's nationals in the heptathlon and entered Worlds in the 400. It's REMARKABLE. Since she gave birth on April 20th, it means Miller-Uibo was almost certainly pregnant at last year's Worlds (280 day gestation period would point date of conception as July 14 and Worlds was July 22.
Meanwhile, Mu and SML have to be begged to compete.
If Miller-Uibo beats SML in Paris, it will be EPIC. Remember she also beat the annointed one Allyson Felix in 2016. If she can take down two of NBC's media darlings, it will be legendary.
