Longuenesse Durathlon 2026

The Longuenesse Durathlon is the perfect plan if you want to challenge yourself without taking it too seriously: you alternate running and cycling, you switch pace, you push again, and you won’t see the race go by 🔥.

You run, you ride, you run again… basically you bike & run, and it quickly becomes addictive: zero monotony, just fun and a little “come back for more” vibe 😉.

As for formats, you pick your menu depending on how you’re feeling: 13 km to get started, 20 km to treat yourself, 27 km to earn respect, and 35 km to have a real story to tell at the finish 🏁.

The best part is the nature vibe at the gates of Saint-Omer: you’re in Hauts-de-France, it’s happening, it’s lively, and there’s always a patch of greenery to clear your head when your legs start negotiating a bit 😄.

And if you’re coming with family, it’s even better: the event also thinks of kids & juniors, perfect for turning the day into a sporty family outing 🌿.

After you cross the finish line, stay nearby to keep the fun going: take a trip to the Audomarois marshes (a waterside stroll), swing by downtown Saint-Omer for a walk, check out the Notre-Dame Cathedral of Saint-Omer, and climb Mont Saint-Frieux if you want a breath of fresh air and a beautiful panorama over Pas-de-Calais.
