Ultramarathoner Dean Karnazes has run across deserts, mountains, and time zones. But his most meaningful marathon? Fatherhood. The legendary endurance athlete shares his take on parenting, purpose, and why leading by example is the real finish line.


Meet Dean Karnazes

From: California + Greece
Kids: Two (ages 27 and 30)
Gig: Full-time adult and part-time legend

If you’ve ever read Ultramarathon Man or seen footage of Dean running through the night, you know this guy doesn’t do “average.” But talk to him about being a dad, and the conversation shifts from medals to meaning. “You only have one crack at parenthood,” he says. “Don’t screw it up.”


The Hardest Part

Even for a world-class runner, parenting came with its own kind of fatigue.
“The hardest part was not stressing over money when the kids were young,” Dean says. “Every day was hectic, crazy, and beautiful.”

Sound familiar? Whether you’re juggling deadlines or diapers, it’s the same balancing act: showing up, staying steady, and hoping the kids see you doing your best.


The Reward

“The lessons we’ve taught each other,” Dean says simply. That’s the real trophy.

He’s quick to point out that his parents have also found joy in the process — grandparenting included. “I’ve enjoyed my kids immensely, but so have my parents. The grandparent experience is special.”


The Wisdom

If Dean has one rule for modern dads, it’s this: lead by example.
“Kids are quick to spot hypocrisy,” he says. “You can’t tell them to exercise and eat well if you’re not doing the same.”

It’s not about being perfect — it’s about being consistent. Whether you’re lacing up for a jog or putting down your phone at dinner, they’re watching.

“A parent must maintain their own life,” Dean adds. “Yes, family consumes most of your time and energy. But don’t lose your outside interests.”

For him, that means running, reading Homer, eating souvlaki, and sipping ouzo. “What more is there to life?” he laughs.


The Takeaway

Dean Karnazes’ parenting philosophy is simple but powerful: don’t just tell your kids how to live — show them. You don’t need to be an ultramarathoner to apply it. Just be the kind of man your kids want to mirror. Be the one who still chases things, still laughs, still finds joy in the daily miles of fatherhood.


Dad Day Takeaway

Be the dad who runs his race, literally or not. Your kids don’t need perfection. They need your pace, your passion, and your presence.
