Triathlon du Sénonais 2026

If you want a triathlon that makes you travel without leaving France, the Triathlon du Sénonais in Sens ticks all the boxes: water, the city, and an atmosphere that gives you a boost 🏊‍♂️.

Here, you get the best of both worlds: the lakes & ponds side to get you in the swim, and the through-town section to enjoy the Sénonais scenery without doing slow-motion sightseeing 🏛️.

You pick your format: the 10.3 km to have fun without freaking yourself out, the Triathlon S solo or relay to come with your crew, or the Olympic (M) if you want a real day of adventure to brag about 🚴‍♂️.

And if you come with family, it’s even better: there are kids & juniors courses, so everyone gets their moment of glory, from the mini-champion to the loud-clapping supporter 👨‍👩‍👧‍👦.

After the finish, stick around: go catch your breath by the Sens Saint-Étienne Cathedral, take a look at the Synodal Palace, stroll through the historic center, and finish with a drink on a terrace near the quays or in a lively square—because here, they also know how to “recover” in style! 🍷
