La Grésylienne is back for its 42nd edition to show you around the area of Grésy-sur-Aix, in the heart of Savoie 📍, in the French Alps, in the region Auvergne-Rhône-Alpes, nestled between the Mont Revard, the Dent du Chat, the Corsuet Forest 🌲 and the Lac du Bourget 🏞️. For this late September, the event pulled out all the stops: new routes, new site 💻, new team of organizers… In short, if you’ve already taken part in La Grésylienne in previous years, forget it all, because a new page is being written by this trail 😎. Their recipe is simple 🤓: a pinch of tradition and a healthy dose of nature and of conviviality 😁.
On an exceptional playing field that will be a treat for your eyes and legs 🦵, you will tread on even more trails 🪨, gain even more altitude gain 📈, and you’ll get to admire even more of the local heritage. Whether you’re a seasoned runner or new to the sport 👶, there will surely be a race that fits you like a glove! 🧤 Three trail courses or long options are offered: the TCC or "Trail Corsuet Crémaillère" from 40.5 km and 1,650 mD+, the TCS or "Trail Corsuet Sierroz" from 25 km and 1,173 mD+, the TBC or "Trail des Balcons Crémaillère" from 15.8 km and 480 mD+ and finally the TBL or "Trail des Balcons du Lac" of 9.5 km and 270 mD+.
