Fresh off their sixth straight U.S. title in the 1,500 meters, Nikki Hiltz isn’t just celebrating a championship season, they’re celebrating themselves.
On August 6, just four days after winning the national title in a tactical, gutsy 4:03.15 at the USA Track and Field Championships in Eugene, Hiltz took to Instagram to share something they’ve kept private for nearly a year, they underwent top surgery last September, one month after competing at the 2024 Paris Olympics.
“For those who may not know, top surgery is a form of gender-affirming care,” Hiltz wrote. “On Sept 13, 2024 I underwent a surgical procedure to make my chest flatter so that it aligns more with my gender identity.”
Hiltz, who came out as nonbinary in 2021 and uses they/them pronouns, said the decision to go public now had nothing to do with seeking attention, and everything to do with creating space for joy, visibility, and belonging.
“I’m not sharing this for validation or opinions (good or bad) because honestly I don’t care,” they wrote. “I love my new chest and that’s all that matters.”
While gender-affirming care and the rights of transgender athletes have become lightning rods in U.S. political discourse, Hiltz’s post was less a political statement and more a deeply personal affirmation.
They described the physical and emotional weight of years spent binding their chest to feel more at home in their body.
“Before surgery I never met a mirror that was my friend when it came to my chest,” they wrote. “Since September, I’ve been so happy in my body, I find myself holding my head just a little bit higher.”
The post was also a message to others in the trans community, “Even though they are banning a lot of things in order to make our lives far more difficult than necessary, one thing they can never ban is our trans joy. No matter what they do to our community I’m going to keep on showing up and keep on shining and I hope you join me in doing the same.”
That message hit at a time when access to gender-affirming care is increasingly under threat. More than 20 U.S. states have enacted bans or restrictions on such care for transgender youth, with some targeting adult care as well.
According to the Human Rights Campaign, 2023 and 2024 saw a record number of anti-trans bills introduced across state legislatures, and many passed. In this context, Hiltz’s visibility matters.

Hiltz is currently training for the 2025 World Athletics Championships in Tokyo, set for September.
While they’ve claimed silver at the World Indoors and made it to the Olympic stage, a major international title has remained elusive. Their win over Sinclaire Johnson at nationals, a final-lap showdown that saw Hiltz kick away over the last 100 meters, suggests they’re peaking at just the right time.
But for Hiltz, racing is only part of the story.
“Gender affirming care is life changing and life saving,” they wrote. “I’m grateful for my Emma, my family, my friends, my surgeon, and for all the beautiful trans people who came before me and showed me the way.”
In a world that often politicizes trans bodies, Nikki Hiltz continues to insist on joy, and to back it up with world-class performances.
