If you’ve never heard the name Ed Whitlock, that’s not surprising. He’s not famous anywhere outside running circles, but he’s inspirational to a number of folks in the medical community because he’s still running. Running marathons. Running marathons in times that put him in the top nine percent of marathoners. And he’s 80 years old.

Whitlock lives in Milton, Ontario, Canada, and a recent article in the Montreal Gazette quoted him as saying good genes and dogged determination are the secrets to his success. If you’re someone who agrees that exercise is vital to well-being, and helps to slow down the aging process, you’ll really enjoy the article.
