Trail Grigne Sud

About the Event

Nestled within the heart of Lombardy's stunning Alpine landscape lies the Grigne Sud Trail. This challenging yet captivating race offers runners an unforgettable journey through the southern slopes of the majestic Grigne range, where nature and adventure converge.
Participants can opt for either the long route, stretching 42 kilometers with a daunting elevation gain of over 3,700 meters, or the shorter but equally scenic course at 22 kilometers with 1,800 meters of ascent. Both routes start from Mandello del Lario and wind their way through verdant valleys and along the shores of Lake Como before ascending to breathtaking heights beneath Sasso Cavallo.
The trail is a true test for both body and mind as it navigates rugged terrain dotted with ancient forests and craggy peaks, offering runners panoramic views of shimmering lakes and snow-capped mountains. Along the way, competitors will have the rare opportunity to spot chamois, graceful mountain goats that call these trails home.
This event is not just a race but an exploration into the heart of one of Italy's most picturesque regions, where every step reveals new wonders of nature’s beauty and grandeur.
Runners can expect challenging climbs and technical descents as they traverse through varied landscapes. The route features well-marked paths that wind around historic villages, passing by charming lakeside towns before reaching the summit trails.
The Grigne Sud Trail promises an immersive experience for trail runners seeking a blend of physical challenge and natural splendor.
Whether you are drawn to its scenic beauty or the thrill of conquering steep ascents, this race offers a unique opportunity to connect with nature while pushing your limits on some of Italy's most spectacular trails.
