There is a particular kind of obsession required to keep returning to the marathon—not simply to finish, but to keep chasing it year after year, long after most runners have stepped away.

For Liam Cotter, a native of Cork, Ireland, it all began almost by accident.

In 2007, Cork’s marathon made its long-awaited return. Cotter was driving through the city with his wife on the way to West Cork when traffic forced them to stop. As runners streamed past, something clicked.

“I remember it vividly,” Cotter says. “I said to myself, I’ll be here next year.”

He was—and with no real strategy. His approach to that first marathon was refreshingly honest: run as far as possible, as fast as possible, for as long as possible. The result was a 3:08 debut.

“I obviously hit the wall,” he laughs. “But it took off from there.”

A year later, the Cork runner lined up at the Dublin Marathon and broke three hours for the first time. Since then, the numbers have quietly mounted: 31 sub-three-hour marathons, including seven under 2:50. Now in his 60s, training under Gary O’Hanlon and John Dillon and racing for St Finbarr’s AC, Cotter continues to produce sub-three performances with striking consistency.

The marathon soon carried him far beyond Ireland. Cotter has completed all six World Marathon Majors—New York, Chicago, Boston, Berlin, London, and Tokyo—three times each.

“My first international marathon was New York,” he says. “To this day, I still think it’s the holy grail. If someone wanted to do just one marathon in their life, I’d say New York.”

That first New York experience in 2010 left a lasting impression.

“The buildup to a foreign marathon, the crowds, the energy—it’s life-changing. Running through the streets of New York gives you a buzz like nothing else.”

Running under 2:50 there only deepened the attraction. And remarkably, Cotter is getting faster as the years go by.

“Since COVID, I hadn’t run a sub-2:50. I had plenty of sub-2:55s and thought maybe those days were over,” he says. “But in 2025 I’ve already run two sub-2:50 marathons. What makes it even more exciting is that I’m over 60 and now getting on the podium at world marathons.”

His recent results underline that point. Cotter ran 2:49 at Valencia, finishing third in his age category, then followed it with another third-place category finish at Berlin, one of the most competitive stages in the sport.

That has sharpened his focus.

“My goal now is to finish on the podium in all six World Marathon Majors,” he says. “I’ve completed them all three times already. This fourth time, I want a top-three finish in each. One is done—five to go.”

With 39 marathons already behind him and no shortage of ambition remaining, Cork’s Liam Cotter shows no sign of slowing. For some runners, the marathon is a phase. For others, it becomes a lifelong pursuit—one that grows more compelling with every finish line crossed.
