Imagine lacing up for seven grueling marathons over the span of seven days, each on a different continent. For many, running even one marathon is a monumental task. But for Estefanía Unzu, the Spanish influencer known as Verdeliss, this was not only a challenge but an opportunity to etch her name in history. She emerged not just as the first woman to win the entire World Marathon Challenge in 2025 but also broke a Guinness World Record in the process.

Estefanía embarked on this odyssey, enduring continents’ extremes—from the icy chill of Antarctica to the sweltering heat of Africa’s deserts. Each step tested the limits of human endurance amidst wildly varied terrains and climates. Her secret weapons? An ironclad training regimen and an unbreakable spirit.

Before a single foot landed on a starting line, thorough medical assessments ensured Estefanía’s body could withstand such relentless exertion. Two sports medicine experts weighed in on her success, emphasizing the imperative of gradual training over months and a meticulously balanced diet rich in proteins and carbohydrates. Rest days, vital for recovery, were a luxury Estefanía rarely afforded herself.

The marathon circuit is notorious for its physical toll. Dehydration, microtears, and cramps become constant companions. Yet, it’s the hidden threats like prolonged muscular stress that lurk in the aftermath, with biochemical byproducts that could spike in the blood for weeks.

In Verdeliss, we see fiery determination coupled with physiological advantages unique to women. Studies suggest they recover faster post-race, and Estefanía’s light frame minimized joint impact, aiding her incredible feat. With unparalleled consistency, women often maintain pace better than men, demonstrating resilience over raw speed.

Estefanía’s odyssey across continents is a testament to the human spirit’s boundless potential when fueled by determination and scientific preparation. Her journey doesn’t redefine resilience—it embodies it.
