Lys Triathlon 2026

The Lys Triathlon is your ticket to a sporty adventure between nature and the city center in Aire-sur-la-Lys, in Pas-de-Calais. 🌿.

Here, you string together the three disciplines in an accessible, punchy format, with just the right amount of challenge to make you smile at the finish line… and make you want to do it again 🏁.

The playground is varied: an urban vibe for the crowd’s energy, and waterside spots like a refreshing break to keep a cool head (yes, the Lys will make you feel at ease… without “leaving you high and dry”) 🌊.

If you’re coming with family, it’s even better: the event also caters to kids & juniors, perfect for turning the weekend into a mini sports festival where everyone finds their happy place! 👨‍👩‍👧‍👦

After the effort, I’ll guide you just steps from the start: take a stroll through the historic center of Aire-sur-la-Lys to wander around, stop by the Saint-Pierre Collegiate Church for a real visual wow moment, then head to a terrace on the Grand-Place before a walk along the banks and nearby waterside spots ☀️.
