Finnish Guinness world record holder Teemu Virtanen is preparing for one of the most ambitious challenges of his career: a non-stop roller skiing journey of over 700 kilometers from Vilnius, Lithuania, through Latvia to Tallinn, Estonia, without sleep and with minimal rest. No one has ever completed such a feat before.

Virtanen holds the 24-hour Nordic skiing world record with a distance of nearly 476 kilometers, placing him among the most remarkable endurance athletes in the world. He has also received three nominations for an internationally recognized award in Hollywood. Now he is setting his sights on something even bigger.

The Baltic crossing will take him through traffic, across changing terrain, and through unpredictable weather conditions, pushing both body and mind far beyond conventional limits. The attempt will be completed without sleep, meaning that as the hours accumulate, the physical and psychological demands will intensify in ways that are impossible to fully prepare for.

A documentary that goes deeper

The challenge forms the centerpiece of a new documentary film, “Across the Finnish Line: The Iron Finn Teemu Virtanen,” directed by Harry Choreus. With more than 30 years of filmmaking experience and a growing focus on psychological themes, Choreus is not interested in simply documenting a sports record. He wants to understand what drives a person to keep pushing.

The film asks difficult questions: what motivates Virtanen to continuously seek out more demanding challenges, and at what point does passion become compulsion? It explores how intergenerational experiences shape the bond between a father and his child, and how extreme fatigue can strip away psychological defenses to reveal something that might otherwise remain hidden.

Choreus is the creator of the ‘Mirror on the Big Screen’ concept, and his work is known for tackling complex and rarely discussed subjects, including the transmission of shame across generations.

A father and son on the road

Joining Virtanen on the journey is his teenage son, Neo-Vilmeri. While his father endures the physical extremes of the challenge, Neo-Vilmeri observes the world and his father with curiosity, critical thinking, and occasional humor. As the kilometers accumulate, an unscripted father-son dynamic unfolds in real time, with fatigue, conflict, small victories, and quiet moments of understanding all playing out on camera.

The documentary asks whether a shared extreme experience can bridge the invisible boundary that exists between generations, or whether some questions will remain unanswered even after 700 kilometers.

“I always want to push the envelope, and after setting the world record for 24-hour Nordic skiing, I set my sights on new adventures. I’m currently working on two extremely ambitious challenges: roller skiing across the USA and Australia, and this Baltic endeavor serves as a springboard for even larger projects. This is something I haven’t done before, and I’m excited — but also a bit nervous — to see how far beyond 24 hours I can go, especially since I’ve completed that duration several times in the past,” Teemu Virtanen tells ProXCskiing.com.

The younger Virtanen admits that his father is an unusual character, but he is thrilled to be part of the father-son journey.

“I have always followed my father’s challenges from the sidelines, but now I finally get to join him on this adventure. This will be a unique experience for both of us and something completely different for us to do together. I’m a bit concerned about the fact that anything can happen on public roads,” Neo-Vilmeri Virtanen shares his thoughts.

Teemu Virtanen and Harry Choreus have previously worked together in Hollywood, and the documentary director is excited to reunite with his former colleague once again.

“Teemu and I have filmed in many legendary locations in the past, so now it’s time to make a documentary about him as a record-breaking legend. It naturally raises the question of what truly drives someone to push themselves all the way to the edge,” Harry Choreus says.

Live coverage and message beyond sport

The project will also be broadcast live through multiple cameras, with audiences able to follow along and engage via social media. The team is currently seeking technical and production partners for the live broadcast.

Beyond the sporting achievement, Virtanen and Choreus want the project to carry a wider message: that age, background, and past experiences do not define what is possible. What matters is the courage to pursue your own goals and to understand why you are doing it.

For Virtanen, this is not a final destination. He describes “Across the Finnish Line” as only the first chapter of a longer journey toward ever more ambitious challenges.

A teaser for the documentary is available on his YouTube channel.
