JUST ONE MORE LOOP

Welcome to a unique ultra-running adventure, where the threads of resilience, community, and adventure intertwine in the heart of Romania.

This challenge is unlike any other – instead of counting kilometers, we reset the timer every hour and count those who remain standing.

Pushing your limits forward into the unknown, this will be the race of your life. You will run till only one stands. But we will live every moment together. One challenge. One community.

We are the Underdogs. But one of us will prove the odds wrong.
