Trail Grigne Sud

About the Event

Challenge yourself on the legendary paths of the chamois at the Trail Grigne Sud on September 26, 2026, in Mandello del Lario. This premier event offers two demanding courses: the TGS Extreme, a 42km UTMB qualifier with 3,700m of climbing, and the TGS Sprint, a 22km route with 1,800m of ascent. The trails carve an epic arc from the shores of Lake Como up to the rugged peaks and dramatic ridges in the shadow of Sasso Cavallo. It's a technically challenging and incredibly scenic journey that requires both strong legs and a determined mind to conquer. Prepare for a pure mountain running experience that showcases the majestic beauty and wild character of the Grigne mountain range.
