Sunday, April 25, 2027

“Proso Olotachos.”
A historic Greek naval command.
A call of direction, determination and purpose.
A timeless order to move forward, with strength, endurance, vision and unwavering course.

With this symbolic message, the 18th International Poseidon Athens Half Marathon returns on Sunday, April 25, 2027, to the Athenian Riviera, where the sea, sport, culture and social contribution come together in a truly unique international experience.

The Poseidon Athens Half Marathon is far more than just another road race.
It has evolved into an internationally recognized institution with a strong social mission and a distinctive cultural identity, promoting the universal values of exercise, participation, solidarity and quality of life.

At the heart of the event remains its long-standing commitment to raising awareness about Diabetes and Obesity, two of the greatest global public health challenges of our time, highlighting the vital importance of prevention, physical activity and healthy living.

At the same time, the event has become one of Greece’s most important gateways for international runners and visitors after the Athens Authentic Marathon, contributing significantly to the international promotion of Athens and the Attica coastline.

In 2026, runners and participants from 90 nationalities and 67 countries joined the event, confirming its international appeal and steadily growing global recognition. For 2027, participation is expected to expand even further, with projections approaching, or even surpassing, 100 represented countries and an even broader diversity of nationalities.

On Sunday, April 25, 2027, runners and walkers from around the world will once again come together along the coastline of Faliro Bay, following one of the Mediterranean’s most beautiful seaside routes.

A route that connects people, cultures, generations and aspirations.
A route that transforms every step into a message of life.

Proso Olotachos.
Towards people.
Towards health.
Towards participation.
Towards the future.
