I was perusing my copy of Race Results weekly this morning and was stunned to see that at the The Run O' the Mill 5-K over the weekend that the outright winner of the women's race was 8-year old Ava Johnson who ran 19:11.
Update: It looks like she's 9 so we've changed the title
I went to the race website and it's a certified USATF event.
I'm assuming that it's an age 8 world record although the age group site I go to doesn't list an 8-year old WR.
Here are the age rankings for women that I'm aware of. See the link to the site below.
