I used to live down the street from John Tracey, back in East Greenwich, Rhode Island, when he was training for Barcelona and what not. And being a runner myself it was pretty cool to know him. Actually my entire family has become quite good friends with theirs, all being at the same schools and town, and still stays in contact. My sister actually went over to ireland to visit his daugher, one of her best friends, and my mom talks with his wife every so often.
I do know that he has moved back to ireland and is living there with his family. i do not think he is still training for anything special, but he has taken up golf and does a lot to promote the sports involvement for kids in ireland. hope this info helps. the link AM Runner gave gives a history of him and stuff. If I find out more I will post it so you can all know.
