The official US record from USATF for Hannah’s age group is 11.35 by Angela Williams (born 1/30/1980, set on 7/28/1995).
Angela Williams won FOUR NCAA Championships in the 100m at USC and went on to win international medals. That’s what Hannah should be looking at. Hannah is larger, which likely hurts her is the start, but if she works on her start some (especially staying down longer in her drive phase) she may be able to get close. I think she will surpass Jodie Williams’ time at the same age (which I think is 11.56), but 11.35 for a female is a different world.
