La guillestroise - Guillestre 2026

La Guillestroise is a 12 km trail race starting from the village of Guillestre in the Hautes-Alpes, near the Queyras and Ecrins natural parks. The main race begins at 9:30 AM and involves 260 metres of elevation gain, positioning it as an accessible trail run rather than a mountain-ultra. The course offers runners a concise view of the Guillestre landscape, with sufficient ascent to feel like a trail but not so much that it deters newer participants. Experienced runners, regular joggers, and children are all catered for, as the event includes kids' races alongside the main trail. A refreshment stop is available for participants, and previous years have seen increasing numbers and a welcoming race-morning atmosphere.
