La Comboitise - Seyssins 2026

La Comboitise is a 10 km trail race in Seyssins, in France’s Auvergne-Rhône-Alpes region. It is usually scheduled for early July, starts in the morning, and packs 320 meters of climbing into a short format, making it more punchy than flat-road 10K racing. The route is a loop mixing urban trail sections with forest paths around Seyssins. Organizer Triple Effort Enthusiasts describes it as a test against gravity, and the terrain requires both endurance and footwork rather than simple road speed. The race uses chip timing, shares entries and practical details through its official site, and is listed in the Jogging International trail and running calendar.
