Infinity trail

Although the figures may be impressive, the format remains accessible to all!

The concept  is simple: run 6.7 km in less than 1 hour, that’s an average speed of 6.7 km/h. Accessible, isn’t it? Whether you’re aiming for 3, 5 laps or more, there’s a place for you! 💪

On the Backyard in Laval, two participants stopped on the 1st lap, and the average for participants was 10.7 laps. No pressure, just the pleasure of surpassing yourself.

This loop format is ideal for testing out longer distances, getting close to ultra trail running or simply beating your own records. Plus, you always return to base camp every hour and are never more than 3km from the start – it’s a safe race, even at night. 🌙

And here’s a statistic that may convince you: 50% beat their distance record and 20% double it!

So what are you waiting for? We’ll see you in 2026!
