Daley Thompson, a former British decathlete who won two Olympic gold medals, spoke out against transgender participation in girls and women’s sports in a video for Fair Play For Women.

Thompson’s remarks came amid controversy over transgender females competing against biological women in sports. Last week, British Cycling prohibited transgender female athletes from competing against biological women. The organization will have an "open" category, which will allow transgender women, transgender men, non-binary individuals and those born male and female to compete.

Transgender men who have yet to begin hormone therapy will be able to compete in the female category, while the current men's category will be consolidated into the open category.

"You only get one chance to win that medal, stand on that podium, make a final," Thompson says in the video.

"You wouldn't let a 25-year-old compete in an under 16s race. Why do we want to disadvantage 51% of the population? Why do we want to take away ambition from our daughters?
