Hilde Dosogne – Marathon Woman 366: Running 366 Marathons in a Year at Age 55 to Break a Guinness World Record

At age 55, Belgian runner Hilde Dosogne set out to break boundaries — and did just that. 

In 2024, she ran 366 marathons in 366 days, earning her the title of Guinness World Record holder for most consecutive marathons in a year. 

What makes Hilde’s journey so extraordinary is not just the distance she covered, but the relentless dedication she showed while working part-time and managing her daily life with laser-focused discipline.

Known as Marathon Woman 366, Hilde didn’t grow up in a sporty family. In fact, she didn’t seriously take up running until her 40s. But once she did, she never looked back — moving from her first marathon with her husband in 2013 to ultra events like the Marathon des Sables and the legendary Spartathlon in Greece.

Inspired by endurance runner Candice Burt, who ran an ultra a day, Hilde set a goal that was bold yet (just) manageable alongside her career — a marathon every single day for an entire year. 

From battling injuries and illness, to running through Belgian storms and even dislocating a finger mid-run, Hilde’s story is one of mental toughness, resilience, and unwavering self-belief.

In this episode, Hilde shares:

• Why she decided to take on this incredible challenge
• How she structured her days and managed recovery
• The highs and lows of running every single day
• The mental strategies that helped her keep going
• Her thoughts on aging, performance, and redefining what's possible at 55
• The deep sense of joy and freedom she finds in running

Hilde’s story is a reminder that it’s never too late to start something extraordinary — and that the only limits are the ones we place on ourselves.
