Εna athletics is proud to welcome to our team Constantine (Dean) Karnazes, one of the most influential figures in global endurance running. With a career that has redefined what it means to be an ultrarunner, Dean joins ena as our Global Ambassador, helping to strengthen our international presence and championing core values such as endurance, consistency, and personal growth through running.
Recognized by TIME as one of the “100 Most Influential People in the World,” Dean Karnazes has completed 50 marathons in 50 states in 50 consecutive days, raced at the South Pole, crossed the Sahara, and won the Badwater Ultramarathon — one of the world’s toughest ultra-distance events. Through his achievements, books, and speaking engagements, he has inspired a global community of runners to redefine their limits. Dean is also a passionate advocate for initiatives that encourage more children to embrace physical activity.
This partnership is built on shared values: dedication, consistency, and respect for the journey—principles that have been at the heart of ena since day one.
Alongside Maria Polyzou and Kostas Chouvardas
With Dean Karnazes joining, ena’s ambassador team grows even stronger, alongside two standout figures from the world of distance running and athletics: Maria Polyzou and Kostas Chouvardas.
Maria Polyzou is the holder of the Greek national marathon record and the first Greek woman to complete the iconic 524 km Athens–Sparta–Athens–Marathon route, paying homage to the legacy of Pheidippides. She has played a pivotal role in advancing the running movement in Greece.
Kostas Chouvardas, both a dedicated runner and coach, is a model of consistency and integrity in long-distance running. He continues to push his boundaries, most recently taking on the “EPTA” challenge—seven marathons in seven weeks, each finished in under three hours.
Εna proudly stands alongside all three ambassadors, recognizing the unique paths they have taken and the strength that comes from their diverse journeys.
A partnership for the future
Our collaboration with Dean Karnazes is rooted in shared values of endurance, consistency, and respect for the journey. In the months ahead, this partnership will unfold naturally, through selected events and initiatives that reinforce ena’s mission: to highlight running as a personal journey with meaningful benefits for both body and mind. Our products, crafted with precision and a focus on performance, are designed to support runners at every stage—from training and racing to the demands of everyday life.
