"Our Uncle Chris has been training for the marathon. He's been pretty fortunate with injuries. Last Saturday he went out on a 17½ mile run and all he came back with was a sore left BLANK."

Please send entries to Uncle Chris, and remember, the clue is in the question. The winner will go through to the Supermatch Game.
