The child should not be competing in the girls race due to the competitive advantage they have. If the child wants to identify as a different gender than what they were born, then that’s fine. However, their choice should not negatively impact others. Now if the child has gone through hormone therapy, then that is a different story.
"Hormone therapy" for the distressed, gender-focused and confused children of this age who are unfortunately being labelled "trans" these days would mean GnRH agonists like Lupron (the cancer drugs now used off-label to block maturation in kids rebranded as "puberty blockers") and - in the case of males - exogenous estrogen as well. In the US, today boys unhappy with their sex/gender are being put on GnRH agonists at 9-11; girls as early as 8. Once on the GnRH agonists, males start estrogen at 11-12. Jazz Jennings began both "puberty blockers" and estrogen at 11.
But even when male children who say they "identify as" the opposite sex are put on these drugs this early, it won't remove all the physical advantages they have over females that make a difference in sports. USATF youth records, and the records of other youth sports, all show that males consistently outperform females in all events starting in the youngest age bracket for which records are kept - which is age 7-8. The data from the USA's Presidents Physical Fitness tests that many American school kids age 6-16 used to take in the 1950s-70s shows the same.
Part of the reason is probably the physical changes that occur, or are set in motion, during the 5-month long male "mini puberty of infancy" that occurs in the first six months after birth. Starting about 4 weeks after birth through the 6th month, baby boys have T levels as high as their T levels will be in the puberty of adolescence. This causes males right off the bat to develop physical characteristics that give them a significant edge over female children in most sports - such as more lean mass, larger and more powerful lungs and hearts that lead to greater cardiovascular capacity and much higher hemoglobin levels, greater bone density, more muscle, faster twitch fibers and so on. During the puberty of adolescence, male hearts grow so they are 25-38% larger than the hearts of females of the same height; but many years before that, the all-important left ventricle in boys is already be 6-8% larger and more powerful than in girls.
That's how it is across the board: the physical advantages males have over females that matter in sports become enormous, innumerable and unmistakable during and after the puberty of adolescence - but boys still have marked advantages before the puberty of adolescence.
Also, by the time a boy is in 8th grade, he probably will already be in the puberty of adolescence since most boys begin puberty around age 12 - and many start as early as 10.
