Kaillie Humphries: Identity is not the same as biology. The Supreme Court agrees

As a three-time Olympic gold medalist , five-time world champion and a proud competitor who has dedicated my life to bobsledding, I’ve had the privilege of competing at the highest levels of sport.

Representing both Canada and the United States on the world’s biggest stage, I became the first woman to ever win gold medals for two different countries. Throughout my career, I’ve witnessed firsthand the power of women’s sports to create opportunities, build confidence, and change lives.

As a professional athlete, my path has been, and will be, written for me. I’ve already experienced immense opportunities that few have — all carried to fruition on the backs of women who came long before me.

The Olympics is a world-renowned event. People from all over the world are drawn in to watch the culmination of years—sometimes a lifetime—of work come to life. The world sees the medals around our necks and podium celebrations, but what they don’t see is the moment before the race, knowing that years of preparation will soon come down to a matter of seconds. It’s in those moments I’m reminded how fortunate I am to be there.

I didn’t achieve those milestones alone. Every opportunity I’ve had exists because generations of women fought for the chance to compete in their own category. Last week, the Supreme Court upheld that Title IX means exactly what it says: to uphold an exclusive category meant for biological women.

Women’s sports were established to exclude men. The exclusivity is what allows girls to earn roster spots, chase championships, secure scholarships, attract sponsorships, and pursue the dreams that girls before Title IX didn’t always get.

Sports aren't only measured by gold medals. Even the 10th place spot can determine someone’s future. Even Justice Kavanaugh acknowledged that sports are a zero sum game.

Every opportunity won by one competitor is an opportunity another loses. For a lot of girls across the country, their spot was bumped because a man came through and took it away from them — and it’s astonishing that this was allowed to happen in the first place.

As athletes, we have a responsibility to protect the legacy of women’s and girls’ sports. Fairness does not mean that there are no boundaries. Fairness means that objectively there is a line that should not be crossed. Equality doesn’t mean that we are all the same in height and speed. It means that women and girls should have equal opportunities within the female category, not a free for all. Sports should never be based on someone's self-proclaimed "gender identity." It should always be based on biology. People have tried to blur the line between the two, but the Supreme Court rightly recognized that they are separate concepts, and that Title IX protects girls because of their biological sex, not because of how someone identifies.

That’s why, when the transgender sports issue began, I didn’t sit on the sidelines—I knew that I had to do something.

This victory was a race of its own. We gathered, we rallied, and we did not stop in the face of the insults and heinous accusations that came our way. Instead, we fought for our rights, just like women did all those years ago.

Someday, another little girl will stand at the starting line that she has dreamed of her entire life. She won’t be thinking about the Supreme Court or the legal parameters of Title IX. She’ll be thinking about the race ahead of her.

My hope is that that little girl who has a dream to compete—from high school to the Olympic stage—will continue to have the chance to compete in a category created for women—biological females—to test the limits of her own ability, and to discover just how far hard work pays off.

Last week’s decision preserves the opportunities that came before me, and if my activism had even a small part in moving the needle on this, that’s a legacy worth leaving.
