The one and only


The OCR Series is the biggest obstacle course racing tournament. The tournament is executed by Strong Viking under the supervision of our Race Director and trained independent OCR marshals.

What’s OCR Series?

The OCR Series is the best way to test your physical and mental strength and endurance. Are you an obstacle runner, trailrunner, crossfitter/bootcamper or another all-around athlete? Conquer our 19km obstacle course race with over 40 obstacles under the supervision of specially-trained OCR marshals. We make a distinction between mandatory (A) obstacles and penalty (B) obstacles. If you fail at one of our B obstacles there is no tapping-out. You get back up do your penalty and keep trying until you make it to the finish. In the meantime your opponents may pass you, so don’t waste any time focusing on your setbacks. However, if you’re not capable of completing our mandatory (A) obstacles, you’re out of the race. Check out all the mandatory and penalty obstacles in our  rulebook.

The penalties vary at every obstacle, from running an additional lap, battle ropes, burpees and so on. You can also find the list of all penalties in the rulebook.

The past season was unfortunately different than others due to COVID-19. But we are going for a fresh start in 2022! This year we will organize one OCR series race in each country where Strong Viking organizes events (Belgium, Germany & the Netherlands). We start in Ghent (BE) in April, to continue to Frankfurt (DE)in May and then go to Wijchen (NL) in June. After the summer we will end the season with an OCR Finals in Ghent (BE).
