I glanced recently at an article on the Olympics by John Piper (here) and I noticed that he has an aside about his great hero "The good Brit C. S. Lewis". He adds "(who’d be happy to see London host the games)". That struck me as a little odd so I looked up C S Lewis and sport on google and the first entry is a wikianswer to the question "What sport did CSL like?" The answer (which sounds right to me) is "C S Lewis did not like any sport very much. He was born without joints in his thumbs and was awkward when growing up, which meant that he had difficulty playing any sport and never got involved in them, either to play or as a fan."
I also noticed a journal article (abstract here) C S Lewis at the 2012 London Olympics a theological analysis of modern professional sport, in particular the modern Olympic Games which sets out to give a theological assessment "in light of some of C.S. Lewis’s writings on pride and humility."
They conclude "by suggesting that the modern professional sports institution and the Olympic movement, while possessing many positive and enriching attributes, requires “wholesale spiritual rehabilitation” due in-part to both individual and national pride. However, we also believe that the modern Olympic Games that are characterised by passionate international sports competition, has many positive and life-affirming attributes and that there is hope of a lasting “legacy”"
