Former American track superstar Marion Jones is releasing her new book, On the Track, which illustrates her life story, including how she dealt with being stripped of her 2000 Olympic gold medals due to her use of performance enhancing drugs.

But most sports fans already know Jones suffered severe punishment for “unknowingly” using steroids, as she claims. According to The Associated Press, she now wants the world to know how remorseful she is for not only lying about the enhancement drugs, but for also lying to federal authorities about her role in a check scamming fraud that left her imprisoned for six months in 2008.

“I went to federal prison because I lied. That’s my crime,” Jones told {the AP.} “I could look back and I can say, ‘Gosh, I wish I wouldn’t have been so trusting.’ But I really wish I wouldn’t have lied. That’s my regret.”

Jones said she wish she could go back and change certain things in her past, but “then I wouldn’t be who I am today, someone who I’m actually really proud of,” she continued. “If I hadn’t gone through certain things, and because I had those six months or whatever – just a lot of quiet time – if I hadn’t gone through it, I don’t know if I would ever have that much time to reflect. A lot of people don’t.”

Jones spent much of her time locked up in solitary confinement after engaging in a fight with another inmate. She told {the AP} that time alone helped her reassess her life, while also reprioritizing her goals and what she considers success.

“My story is unique, in that the first part of my life, my journey, I hit the pinnacle of my career, and it was a very public career, and then I made decisions that cost me all of that,” Jones said. “And so I was at that low point. But I didn’t give up. I kind of developed a way to get out of that, and I’m on my way back up.”

Jones, still a very skilled athlete, bounced back in professional sports by signing with the WNBA’s Tulsa Shock last season, but the 35-year-old Los Angeles native may be running out of time on her athletic career.

But she can still rejuvenate her life, starting by helping others learn from her own mistakes, she said. “By helping people, it’s a form of healing for myself, because I hurt so many people. I know that,” she told the AP. “I still struggle with knowing that I let a lot of people down. I disappointed a lot of people that love and care for me, worldwide, and when I think about that it kind of gives me the motivation to kind of keep going on.”
