Istr'M 2026

With Istr’M, you come to seek a true breath of fresh air between city, nature, and seaside vibes, all located in Istres, in the heart of the Bouches-du-Rhône 🌊.

You have a choice between two formats: the XS (solo or relay) to fully enjoy yourself without overdoing it, or the M (solo or relay) for a longer, more intense adventure 🚴 .

And if you're coming with a group, it's perfect: there are also kids & juniors courses, so everyone gets their moment.

After the finish line, stay around: take a breath by the Étang de Berre, tour the city center of Istres for a drink on a terrace, climb up to the Castellan for the view, or head towards Fos-sur-Mer if you want to extend the seaside experience.
