At one point when he was in college at Kansas State University, Jon Smith would jog as many as 20 miles a day.
“If I wasn’t in the library and not in class,” he says, “I was running.”
But Smith was far from healthy.
His over-the-top regimen was a manifestation of an eating disorder known as purge-type anorexia, hints of which first surfaced when weight gain from migraine medication made Smith a pudgy fifth-grader. His training obsession began two years later during preparations for the Junior Olympics.
