Introducing the Obscura Series: A New Way to Race in 2027
We are shaking things up for the 2027 race season, and we think you are going to love what's coming.
In June 2026, we introduced something completely different with Ultra Obscura in Sutton, Quebec. It was a new kind of ultramarathon that combined endurance, strategy, and a little bit of mystery. We had great feedback, and it started us thinking… Why stop at one race?
For 2027, we are taking the Obscura concept even further with a three-race series that will challenge runners to rethink how they race, how they compete, and just how far they are willing to push themselves.
What Is an Obscura Race?
No fixed distance. No need to commit in advance. Just you, the trails, and the question: How far can you go?
The Obscura race format combines the best elements of a traditional loop race and a timed ultra, with a twist that changes everything. It is designed for both crushers and new ultra runners.
Each race features three different stages that are repeated in order. Solo runners can now decide how many stages they want to complete; you do not have to decide your distance before the race starts. Teams still run the full course as described in the race rules.
Feeling great? Keep going. Having a tough day? Finish the stage you are on and call it a race. Want to see if you can push beyond your longest distance ever? Here's your chance. You can keep it to just a couple of stages, or go farther and break the 50km barrier for a full ultra. As long as you complete at least one stage, you will earn an official finish time. This is going to mean a lot more finishers as we try and push you a little farther. But here's where things get even more interesting…
