Hannah Arensman is an American cyclist who has won 35 times on the national cyclocross circuit, but she is retiring from the sport due to transgender women (biological men) entering races.

Arsensman’s decision to retire due to the emergence of transgender cyclists was shared in an amicus brief filed to the Supreme Court last week. The timing of her retirement is noteworthy as she came to the decision after finishing fourth place in between two transgender females in a race.

“I have decided to end my cycling career. At my last race at the recent UCI Cyclocross National Championships in the elite women’s category in December 2022, I came in 4th place, flanked on either side by male riders awarded 3rd and 5th places. My sister and family sobbed as they watched a man finish in front of me, having witnessed several physical interactions with him throughout the race.”
