In late October, when the mist clings to the river, Sablé-sur-Sarthe swaps the monks’ silence for the drumbeat of footsteps 🙂. You then head back up the Sarthe to Solesmes, nose in the fog and sneakers following in the Benedictines’ tracks. This trail drops you right into the heart of the Pays de la Loire, where towpaths skim the water without ever hurrying 🌿. Three distances on the menu: 6.7 km, 12 km or 30 km, served with the same dessert: the abbey right on the finish line. The air hovers around 10°C and the valley’s dampness shows up as soon as you wake up 🍂. Plan on layers, because at daybreak, Espace Henri Royer is more chilly than warming 🥶.
The route follows the Sarthe from start to finish 😄. From Sablé, you head upstream along the towpaths, a smooth, flat ribbon between locks and curtains of willows—the kind of section where you could almost run with your eyes closed. The track slips through Juigné, Avoise then Parcé-sur-Sarthe, before pushing through the gates of the Château de Dobert 🏰, a private estate opened to you only once a year 🔑. Then comes the springy woodland, followed by two or three false flats that sting the legs, just to remind you that the word “trail” is definitely hiding behind all this apparent calm 😮💨. The long format lines up 219 mD+, enough to warm up the thighs. The final turn drops you in front of the Saint-Pierre de Solesmes Abbey ⛪.
To each their own penance 😅. The Trail des Copistes over 6.7 km gets you going for the length of a warm-up, the Trail de l'Abbaye over 12 km lets you take in the scenery, the Trail des Bénédictins over 30 km demands a bit more sweat before absolution 🥵. All pay tribute to Prosper Guéranger, a child of Sablé who, in the 19th century, bought back the ruined Solesmes monastery and turned it into one of the greatest Benedictine centers in Europe ⭐️—nothing less. Linking his birthplace to his abbey is closing the loop on his life… in small strides. The organization focuses on heritage rather than the stopwatch, in a laid-back outing vibe 😌. Sunday beginners or sharpened trail runners, everyone finds the right fit.
After the finish, it’s time for a tasty reward 🍽️. Sablé even gave its name to a biscuit, so you can say the post-race refreshment plays at home—provided the local rillettes haven’t already cut your legs out from under you 😋. Push on to the Château de Sablé, now home to the reserves of the National Library, or lend an ear in Solesmes where the monks still raise Gregorian chant 🎶. The valley keeps its locks and riverside taverns to help you come back down gently. In Solesmes, even the calves end up singing in chorus 😄.
The long format lays out the whole program 🥾. From Sablé, you head back up the Sarthe along the towpath, a long, rolling false flat that rewards steady runners. The route then pushes through the gates of the Château de Dobert in Avoise, drops into the Bois des Tailles with its leg-breaking surges, then sends you back toward the water 🥵. The 219 mD+ are swallowed up on winding paths and a few singletracks, without ever pinning you to the wall. The final descent spits you out at the foot of the Saint-Pierre Abbey of Solesmes, where the walls plunge into the river ⛪.
The intermediate format doubles the distance without changing the vibe 🌿. Still that smooth towpath ribbon, punctuated by a few pick-ups and a false flat or two that wake up the thighs. The route flirts with the banks, slips through a short stretch of supple undergrowth, then sends you onto the final section toward Solesmes 😮💨. The 78 mD+ go down gently: ideal for a first trail that’s a bit more serious.
The discovery format starts from the Espace Henri Royer and heads straight along the towpath 🙂. A smooth, almost flat route, perfect for a first race bib or a family outing. You follow the Sarthe right by the water’s edge, between willows and locks, before the small rise that drops you in front of the abbey 😌. The legendary scenery without pushing you into the red.
