About this event
Ready to explore the pearl of the Mancelles Alps by running? The Grand Trail of Lac de Sillé offers a 100% trail weekend blending wild nature and heritage, with routes ranging from 8 km to 90 km, including 24, 44 and 90 km with D+ from 150 to 1,700 m. In the heart of the Sillé-le-Guillaume state forest, forest tracks and technical trails provide views of the lake and a friendly and authentic atmosphere around Camping Seasonova and the refueling stations.
Ready to explore the pearl of the Alpes Mancelles while running? 🌲 The Grand Trail of Lake de Sillé invites you to a 100% trail weekend, in a setting of wild nature, historic heritage, and a high-level sporting challenge. If you thought Sarthe stopped at the straight line of the Hunaudières 🏎️, get ready for a serious visual shock. Here, every stride brings you closer to incredible landscapes and an adventure your quads won’t forget 🏔️. We ditch the tarmac and switch to exploration mode in a setting that can rival even the farther massifs. Late September in the Pays de la Loire objectively offers the best weather. The heat is gone ☀️ and winter hasn’t arrived yet ❄️. You’ve got everything you need to perform! 💪
The journey starts Saturday evening with a bright starter. The night trail "À la Découverte de Sillé" offers you a full immersion in the historic heart of Sillé-le-Guillaume 🏰. By the glow of your headlamp 🔦, you’ll weave for 14 km past the city’s finest buildings and iconic sites, in a softly lit atmosphere 🏰. It’s your chance to discover local heritage from a new angle, before enjoying a fuel stop and a gourmet finish to kick off the weekend festivities 😈. On Sunday, the vibe shifts to a new dimension with four formats suited for all levels, from curious beginner to kilometer-hungry ultra-trailer 😍. For the boldest, the "Tour of the Alpes Mancelles" will unfold its 90 km and 1 700 mD+ 📈. It’s a real feat of bravery, disguised as an ultra-trail and labeled ITRA & UTMB INDEX, pushing you to your limits. If you prefer a marathon format, the "Maratrail du Cerf" awaits with its 44 km and 1 000 mD+. If you’re more into speed or mid-range distances ⚡️, the "La Boucle du Cerf" (24 km / 500 mD+) and "La Ronde du Chevreuil" (8 km / 100 mD+) will offer you nerve-wracking and stimulating terrains 🦌. And if you’re insatiable and can’t decide, the "Challenge 2 races" lets youback-to-back Saturday and Sunday to test your endurance over time 🎖️.
The course expertise lies in this careful blend of forest paths 🌳, technical trails and open lake panoramas 🛶. You’ll navigate the heart of the Sillé Forest National Nature Reserve (on foot, not by boat, that would be too easy 🤪), a green treasure you’ll crave (or dread) for another three weeks 😮💨. It’s far from monotonous: terrain changes, ground can slip under your feet, and the lake view keeps reminding you why you signed up 🙃. It’s wild, it’s raw, and that’s exactly what we’re after when signing up for a trail of this caliber 🌲. On-site vibe mirrors the locals: friendly and authentic. Right next to the start village, the Camping Seasonova de la Forêt becomes the runners’ HQ to rest, refuel, or extend the adventure with family ⛺. You’re not just here to run; you’re here to share a moment with other people just as passionate as you 🫣. From team challenges for companies or clubs to rewards for 100 % female collectives 💕, the team spirit is everywhere 🤝.
After enjoying the event, take time to taste the local terroir that has real character (just like the trail, you’re starting to get it...) 😬. We don’t leave Sillé without paying homage to the famous rillettes de la Sarthe, perfect for post-race recovery 🥖. For fans of old stones 🗿, the Castle of Sillé-le-Guillaume, a imposing fortress overlooking the town, is worth a visit after your race. If you still have energy in your legs 🦵, a walk to the Saut du Serf or a boat tour on the lake will finish your weekend in style 🚣. It’s the perfect spot for a total quiet escape, far from the urban rush 🍀.
So, what are you waiting for to join the pack? 🐺 Put away the console, skip your series, and come romp on the Sarthean trails. Your legs may grind, but your spirit will gallop well past the finish line 🏁.
