"I never set out thinking I would cross a line, I set out simply wanting to compete, to race my bike and do what I love. And that is exactly what I did, clean. Then, after years of doing things the right way, I was presented with a choice that to me, did not feel like a choice at all. In the environment that I was in, it felt like something I had to do in order to continue following my dream. I crossed the line, and that is something I will always be sorry for," he said.
