Tomasz Sobania, brand ambassador for NILS, has completed one of the world’s most extreme running challenges. The Polish extreme runner ran 50 marathons in 50 US states in 49 days, setting a new world record. The project began on 10 May on the Golden Gate Bridge in San Francisco and concluded with a grand finale in Times Square, New York.

50 marathons, 50 states and an adventure across the whole of the USA
Tomasz Sobani’s challenge was not only a sporting test of endurance, but also an extraordinary journey across the whole of the United States. Every day, Tomek covered the distance of a marathon in a different state, tackling a new route, changing conditions, fatigue and the need to fully recover before the next stage.
The initial goal was to run 50 marathons in 50 US states in 50 days. However, Tomek completed the project sooner — in 49 days. In the final stage, he ran two marathons within a single day: in New Jersey and New York.
This achievement required immense determination, mental resilience, consistency and flawless organisation. Every day was a story in itself, and every marathon was another step towards the world record.
From the Golden Gate Bridge to Times Square
Tomasz Sobania began his journey on 10 May 2026 on the legendary Golden Gate Bridge in San Francisco. Over the following weeks, he travelled through every US state, including Alaska and Hawaii.
The challenge culminated in Times Square, New York — a place that became the symbolic conclusion to this record-breaking journey. From the west coast to the heart of New York, Tomek proved that a passion for sport can take you a very long way.
NILS ambassador on his way to a world record
For years, the NILS brand has been inspiring people to get moving, enjoy the great outdoors, travel and discover the world on their own terms. Tomek’s challenge fits perfectly with these values — it combines sport, adventure, perseverance and a willingness to step outside one’s comfort zone.
As a NILS ambassador, Tomasz Sobania shows that physical activity can be more than just a workout. It can be a way to explore new places, build character and prove that our limits are often further away than we think.
His record-breaking run across the USA is a story of courage, determination and the power of dreams that don’t just remain plans, but set off on a journey.
Sport, adventure and pushing boundaries
In the ‘50 Marathons in 50 US States’ project, every day was a challenge. Changes in route, climate, terrain and the pace of travel required not only excellent physical preparation but also the ability to adapt.
It is precisely this element that makes Tomek’s feat so closely aligned with the NILS brand philosophy. Whether we’re talking about an expedition, leisure, training or everyday exercise — the most important thing is to set off and see how far you can go.
And in Tomek’s case: how far you can run.
Congratulations, Tomek!
Tomek, congratulations on breaking the world record and completing the challenge of running 50 marathons in 50 US states in 49 days.
It’s an achievement that’s impressive in its scale, but even more inspiring in the sheer determination, courage and hard work that went into every single kilometre.
As the NILS brand, we are proud to support an ambassador who demonstrates that activity, adventure and perseverance can create stories that make their mark on the world stage.
May this record-breaking journey serve as an inspiration to everyone who has their own ‘impossible’ dream in mind.
