Triathlon and Duathlon of the Audomarois 2026

In Arques, you come for a triathlon… and you leave with a real breath of fresh Hauts-de-France air, between calm water, greenery, and a mood that’ll put a smile on your face 🏊‍♂️.

The Triathlon and Duathlon of the Audomarois is the perfect event if you want to enjoy yourself without taking things too seriously, with formats to challenge you at your own pace: 12.9 km to get started, then 25.75 km and 27.5 km to add a little more spice to the day 🚴‍♀️.

Here, nature is part of the bib: you’ll make your way through lakes and ponds, and you can feel that you’re not just “racing,” you’re out for an epic big-day adventure… except there are cheers and a finish line waiting for you 🏁.

And if you come as a family, it’s even better: the event also caters to kids & juniors, so everyone gets their dose of adventure, from the smallest to the most motivated (you) 😉.

Once you’ve got the medal in your pocket, don’t rush off too fast: just nearby, you can go for a stroll in the Audomarois Marshes to extend that “nature” vibe, head over to Saint-Omer for a nice city break, or go see the Fontinettes Boat Lift, the spot that reminds you that around here, even the boats gain elevation… without breaking a sweat 🌿.
