Lyell Grunberg is a professional slackline performer from Switzerland.

Having 7 years of experience, he has grown to be a versatile athlete and performer also being part of the best trickliners worldwide. Lyell is slacklining as a full-time career since June 2016.

100+ performances, shows, workshops, courses and talks in 20+ countries, traveling and meeting the slackline community worldwide - he is well-known for his never-dying motivation and his will to teach and learn something new everyday.


In the talks I give generally close with the following:

My favorite quote comes from the book Into the wild, the story of this young man who leaves to the most remote places of north Canada hoping to escape from society, in search of true freedom. It is at the moment of his death, alone, poisoned and far from all human life that he shares his most important discovery:

Happiness is only real when shared.

This is how I feel every time I get off the line.

My mission as a slackliner is to inspire people to balance every single aspect of life. Walking on the line is only a practical way of seeking balance in everything I do.

Our dreams and biggest projects become true a step at a time and it is often a long and hazardous process to achieve them. We always try to focus on the present moment, to stay grounded while being sometimes hundreds of feet off the ground.

Things always seem impossible until their done.

These challenges motivate us to spend every free moment on the slackline and enjoy the diversity, magic and uniqueness of this sport and art to its fullest.

Perfect balance and immobility can never be attained. On a slackline we are constantly falling. I believe it is the same for us in life and each and one of us has to learn to balance and use each opportunity to learn something new everyday.
