One American competitor in the London Olympics has taken a unique approach in his preparation: He's decided to let God be his coach.

Marathon runner Ryan Hall, 29, split with his coach two years ago after he questioned Hall's commitment to win. The young Californian athlete had just been diagnosed with an underactive thyroid.

"Once I knew he kind of lost faith in me a little bit, that was a real shifting point," The New York Times quoted Hall. "My coach has to believe in me. That's the most important thing, probably."

Instead of hiring a replacement, he claimed God as his coach.

"I was sick of saying I'm a Christian but not having a desperation for God in my life," Hall told USA Today. "I wanted to need God. I wanted to make my faith more active in my life."

Hall talked more about his story on the CBN News Channel's Morning News, July 31. Click play to see the interview.
