As well as soothing his soul, running has also brought Singh unexpected fame -- he appeared in an Adidas advertising campaign along with soccer superstar David Beckham and boxing legend MuhammadAli in 2004.
Neiman's powerful imagery of the boxing ring, including fight posters and program covers for the historic Muhammad Ali-Joe Frazier fights, earned him a spot in the International Boxing Hall of Fame in 2007.
After a screening, Mr. Roach said he was surprised to see how much his hands shook from his Parkinson's, a condition likely caused by punishment he sustained as a fighter. (Muhammad Ali suffers from it.) He may be the top boxing trainer in the world now.
