Miller-Uibo had her first child back at the end of April.
She's currently competing in the heptathlon (against her sister too):
100H: 14.60w
HJ: 1.63m
SP: 11.83m
200: 25.31
Day 1 score: 3116
She has a bye to World Championships as the defending champion in the 400m. Will she go to Budapest to try to defend? I doubt she'll get a heptathlon qualifier.
