From Depression to Ultramarathons: David Hooper on Mental Toughness
David Hooper went from clinically depressed and morbidly obese to ultramarathon runner — and built a business from the same quiet resolve that got him off the floor.
In 2017, David Hooper had spent his entire career working toward one dream job. He got it — and then lost it. What followed was six months of avoidance: not leaving the house, an 80-pound weight gain, clinical depression diagnosis, and a Christmas dinner where his shirt was too tight to eat. At that moment, he looked in the mirror, and made a decision. The spiral had to end. He was so unhappy. And that moment laid the foundation for everything that followed.
What David did took true courage. He faced his own pain and looked at his life with true honesty, and—with some help from his pets, and his wife—compassion.
He reframed each of his three main challenges — his weight, his lost job, and his depression — and found an opportunity inside each. His obesity became a chance to rediscover the athlete he’d been as a kid. The job loss became the push to start his first company. And his depression led him to explore what actually made him feel fulfilled. Over the next six months, he lost 80 pounds and started running — the first time collapsing within 45 seconds, still in sight of his garden gate — and eventually became an ultramarathon runner.
One thing he said has stuck with me: when you think you’re completely exhausted, you’re only at 40% capacity. The mind quits before the body has over 60% to go!
We also discussed AI through a lens I hadn’t heard before — not just as a productivity tool, but as something uniquely useful for introverted leaders. David uses AI as a thinking partner that helps him draw his personality out. A partner to reflect with, challenge assumptions, and help him turn his business ideas into executable plans. What struck me is how well this fits the introvert experience. Many of us have rich inner lives that don’t always make it cleanly into the world. AI can help surface, sharpen, and organize those thoughts without some of the social friction that gets in the way.
This episode is worth a full listen. David is generous, honest, and speaks from the heart.
