I was watching a TedX video where Michael Marckx from California claims to have been on the US national triathlon team and won an amateur world championship when he was 23. A 5 minute google search didn't turn up anything, so I was wondering if any of our historians here know anything about it. I am guessing it would have been about 1987 or 1988.
