"I'm just really excited about it. I don't think people really expected me to get on the podium, so to get silver, that is something," Muhammad told USA Track and Field's website.
"You know I tried to get out good and hard, but not go out too fast and die at the end. I was really able to run my own race being in lane six. I didn't really have anyone in front of me to push me along. My mom came out to support me, so I'll probably just be celebrating with her tonight."
