The former Olympian penned a blog post on Monday titled "How I Conquered My Biggest Fear at the ESPYs" about overcoming her fear of public speaking and stepping onstage in a custom Versace gown to accept the Arthur Ashe Courage Award.
"Getting glamorous for the ESPYs was a big process to go through, but it was amazing and so much fun," Jenner wrote. "I really wanted to feel real comfortable up there (although there was a corset under that dress, so I don’t know how comfortable I was!). I wanted to feel good. I wanted to feel pretty. I wanted to be myself."

Jenner admitted that she was nervous about walking onstage in her floor-length gown (which was designed for her by Donatella Versace), but that U.S. Women’s Soccer star Abby Wambach, who introduced her award, helped make sure she didn’t stumble. She also admitted that the hardest part of her speech was talking about her family, and that it was "a little difficult" to watch her speech when she rewatched the awards later.
"While I felt like I looked great and that the gown looked fabulous, I still have a voice issue," she wrote. "It’s not quite right compared to my feminine appearance. That bothers me a little bit. However, I hope that people don’t listen to the pitch of my voice, but listen to what I have to say. That’s important to me."
Jenner said she was finally able to relax at the ESPY after-party, calling the celebration with family and friends "a wonderful moment."
"Thank all of you for your support," Jenner concluded. "Getting up there on stage in front of the whole world was no easy feat, but I so appreciate your encouragement and love. We’re changing hearts and minds one at a time."
