The event in a few words
Close your eyes and imagine for a moment: a trail race in Italy 🇮🇹, on the shores of the splendid Lake Como, located north of the metropolis of Milan 😍, in Lombardy.
We’re heading to the Trail Grigne Sud, a sporting event held in Mandello del Lario 🗺, a town located 200 m above sea level, on the shores of the lake. A race setting in the heart of majestic mountains with postcard-worthy views 🖼️, and a race with a demanding and very technical course 🧐. It’s no coincidence that the event counts toward the UTMB World Series circuit... The start line will be competitive! 💪 Two courses are offered by the organizers: you can choose between a trail of 42 km, the "TGS Extreme", and a trail of 22 km, the "TGS Sprint" 👟. For the boldest who choose the "TGS Extreme", plan for 3,700 mD+ 🥵—you’ll see for yourself that it lives up to its name! 🫢 It’s also a reminder that vertical races were born in Italy; the French 🇫🇷 aren’t the only ones enjoying the exceptional Alps massif ⛰️. Promoting inclusivity and trail running for all, the TGS also offers a course dedicated to children in situations of disability: the "TGS Intrepid"! With 400 mD+ over 6 km, it’s a real challenge awaiting the youngest among us 🔥.
The race takes place at the very beginning of autumn, in the month of September, when the Indian summer often shows up and lights up nature 🌸. So this short trip to northern Italy will let you extend the summer illusion and feast your eyes! 👀 If you want to make the most of your Italian stay and do a bit of sightseeing, Milan, located an hour’s drive away, remains an unmissable major city with its beautiful cathedral ⛪️! Beautiful Verona, the city of Romeo and Juliet 🫶, is a bit farther but well worth the detour too! And if you decide to stay and explore the wonders of Lake Como, there are a few gems not far from there—starting with all the renowned villas, some of which can be visited. We can’t help but mention Villa Carlotta, a magnificent 1690 residence that houses a vast art collection 🎨 and an exceptional botanical garden 🪴, which is one of Italy’s great gardens.
So, are you in? 👢 Head to northern Italy for an unforgettable trail moment 🤩.

A word from the organizer:
"The TGS is a very demanding race due to its significant elevation gain, but it offers a well-maintained course with unforgettable views over the lake and the Grigna mountains. A large team of volunteers, stationed at aid stations and out on the course to mark the route, are there to support runners every step of the way."
