How we Stack Up

See how we compare to other obstacle races

The things we do best


All our races are local to Northern Colorado residents. No driving 5 hours to and from the event.


We take community seriously. That's why every event we host gives in some way. We've given to orphanages and local volunteer fire departments.


No hidden fees at checkout or crazy parking and spectator fees. Our races don't break the bank.

Moving Forward

We're a newer race, and our goal is to always be improving. To us, it's all about making obstacle racing a fun experience accessible to all!

Cerus vs The Others

What Experts Are Saying

Absolutely a fantastic setup, vendors, and course! Thank you Cerus for putting on a serious challenge today! And great race to all the racers!
CEO, Corey Rigitello
They grade out very high with their creative blend of OCR, rucking, and ninja style obstacles as well as their new branding and medals. If you are looking for something a little different in Northern Colorado, look no further than a CerusRuk race.
It was a great mix of obstacles that made normal easy obstacles that little bit harder with the ruck. It was nice change to actually run in the mountians for a Colorado race. The race was well organized, easy check in, fun family atmosphere, with challenging obstacles and the weather made an amazing race an epic race.
