First time I ever heard of Ironman

I've always meant to write this story.

I was really young. I must have been in 7th or 8th grade and I was flying to Florida with my family. I was sitting next to this woman who told me all about this race she had just done in Hawaii. Swimming, biking 100 miles, and then running a marathon. She described how people crawl across the line and some people lose control of all their bodily functions while running.

I was hooked. Of course I can't remember exactly when it was, nor can I remember her name. I don't remember what she looked like or anything like that.

I just remember her description of the Ironman.
