Run with love

Today, more than ever, we need to express love.
To live in harmony with nature and all human beings on this planet may not be the easiest task,
but the most important one. Acts of kindness and trust, and to love and care for one another,
will always overcome hate and fear. So let’s spread the energy of love! 

This is why we love Ultra Running
When we run, we challenge ourselves. And in every challenge there is a possibility for change.
If you manage to go outside of your comfort zone, even if it’s just in running,
you continue through life with the new experience that you can grow. And change things to the better.
Ultra Interval Challenge offers a huge challenge, and who knows, if you dare take on this challenge,
maybe together we can change the world?

Why "Run with Love”?
We hope to inspire you to share the warmth and energy you get from running.
From being brave, from achieving your goals and from growing. 
We hope to inspire you to Run with Love.
