September in Gold 2026

In Treffort, in the heart of Isère, you come looking for a race that smells of forest and nature, and you leave with your head full of images 🌲.

September in Gold is a local playground just the way we like it: rolling trails, shady woods that cool you down, and that little taste of adventure just a stone’s throw from the village ✨.

You choose your dose: 8 km to enjoy yourself without burning out, or 12 km to keep the good times going and snag a bit more green ⛰️.

And after the effort, stick around: take a trip to Lake Paladru for a swim or an ice cream, head up to Chartreuse for a panoramic walk, or make for Grenoble for a drink on a terrace and a city break 🍻.

If you’re coming as a duo or with family, it’s a no-brainer: a stroll by the water, a little snack in the village, and a sunset over the ridges — enough to turn your race into a mini getaway! 😎
