BMX rider Chelsea Wolfe will be traveling to the Tokyo Games as an alternate, and in doing so, will become the first transgender Olympian in Team USA history.

Wolfe qualified for the position by earning a fifth-place finish at the World Championships, but will only get a chance to compete in the Olympics if either qualifying rider Hannah Roberts or Perris Benegas drop out.

In an Instagram post, Wolfe reacted to her historic accomplishment.

'It's taking a bit to fully register that after so many years of work we finally have the @teamusa bmx freestyle squad for the @olympics, and that after so much work and overcoming so many obstacles that I've qualified to represent the United States as the alternate rider,'she wrote.

'I am positively a different person than when I set off on this journey and I'm so grateful for every experience along the way and I'm so excited and honored to keep working so I'm ready to shred in Tokyo in case I'm needed.'

Born and raised in West Palm Beach, Florida, Wolfe began racing competitively when she was just 6, spending her evenings riding around her local skate park.

When she turned 15, she traded in her regular bicycle for a trick bike and started riding freestyle. For many years, she competed with male athletes, hiding her identity as a trans woman.
