OCR SERIES

Strong Viking’s OCR Series

The OCR Series by Strong Viking, named the Best OCR Series in Europe, brings together the top obstacle course racers from around the world. Are you a trained athlete ready to compete against the best? Sign up for the competition wave, aim for a top ranking, and you might even qualify for a championship!

With time tracking and 40 OCR-certified marshals ensuring fair races, missing an obstacle could result in a penalty round or physical penalty that affects your final result. This pushes every participant to give their all. Do you dare to take on the challenge?

19 km with exclusive obstacles

The OCR Series is the perfect way to measure your fitness, strength, and techniques. During our Beast distance of 19km, you’ll face 40+ obstacles, including exclusive (hardcore) obstacles specifically for the OCR Series. The OCR Series starting wave is always the first to begin at Strong Viking events and has a limited number of spots available.

At the end of the races, the winners of the event will be announced during the podium ceremony. For more information, visit www.ocrseries.com.
