Harleysville runner Keith Tindall set out more than a decade ago to run 50 marathons, one in each U.S. state. Jamie Apody, 6abc, reported his reaction to successfully completing that quest.

Tindall crossed his last finish line appropriately in Hawaii, the union’s 50th addition.

“Each medal took about four hours or less. But overall it was about 15 years to earn the whole thing. So yeah, a big deal,” he said.

The varying terrain he’s crossed kept him engaged along the way.

“That’s been the neatest part about it,” Tindall said. “Just getting to see this country, all the states. A lot of them I’ve never been to. There’s flat ones, hilly ones, high altitude, low altitude.”

Receiving his last finishers’ medal was an “emotional” experience, according to Tindall.

“When you put that much work into something … and your whole family is there … I can’t believe I did it.”

Tindall’s not retiring his running shoes, either. His next challenge is a summer run across the entire Commonwealth of Pennsylvania, a 30-day, 460-mile course.

The effort will raise funds for Destiny Rescue, a children’s protective nonprofit in Indiana.

Tindall’s training regimen for that next feat?

“Just run a lot,” he laughed.
