The Trail des Forts de Besançon is a real excursion in the region of Bourgogne-Franche-Comté that will let you discover, among other things, the birthplace of Victor Hugo ✍️, in the heart of the Doubs department 📍. A race in early May 🌼 is really the best in terms of weather conditions! 🌤️ For this edition, the organizers wanted to please as many people as possible by putting 9 distances and 1 challenge on the program, in addition to the traditional kids' races 👧: a 5.4 km "night time trial" with 150 mD+, an 11 km hike and trail with 360 mD+, two guided walks of 8 km and 6 km, a 5 km parasport course, a 17 km duo with 700 mD+, a 22 km with 700 mD+, a 42 km with 1,400 mD+, and a 72 km with 2,800 mD+ that you can run solo 👤 or as a relay. On top of that, there's a 2-day challenge, combining 3 events, for a total of 38 km. You see, there's plenty to do! 😈
Let's start our overview of this great sporty weekend with an event that's not very common in running: the time trial ⌚️. "Do they think they're the Tour de France or what?" 🚴♀️. It's true that it's more often our cyclist friends who face this solitary effort. For this Saturday Night Fever, 5.4 km of urban 🏙️, explosive 💥 and above all brand-new 🆕 terrain await you for a guaranteed show. Whether it's the hike or the 11 km trail, this same course, just hosting a different discipline, will take you through the Citadel of Besançon and along the banks of the Doubs 💦. This circuit is a clever mix of nature 🍃 and heritage 🏰, and is ideal for discovering the city from a new angle 👀.
The 22 km follows the same program, but adds, for your greatest pleasure, detours through the countryside via the Bregille hill and Morre 😁. As for the 42 km, it will give you the chance to cross several forts from the 18th and 19th centuries 🛡️. Finally, the 72 km will link all 12 forts that protect the Vauban city, listed as a UNESCO World Heritage Site. This technical and historic route won't let you miss anything of the richness and diversity of this unique course 👆, which you can also share as a relay 👥. Did we forget something? 🤔 But of course, the "3-Event Challenge"! You'll start with the 22 km on Saturday morning, then the 5.4 km "Time Trial" on Saturday evening, before finishing with the 11 km on Sunday morning. If our math is right, that makes 38 km for a total of 1,210 mD+ 📈. We hope you've prepared your thighs well, because things are likely to heat up a little 🔥. All in all, exceptional panoramas 🤩 await you, whichever event you choose, whether through the landscapes 🏞️ or the rich cultural heritage. The loops around the Doubs will take you through the most beautiful places in Besançon, notably its historic city center, as well as its surroundings 😉.
And after discovering the architecture and the past of Besançon, you can extend your weekend by visiting the Museum of Time 🕰️ or the Museum of Fine Arts and Archaeology 🦴. If your legs are still heavy, don't hesitate to go for a stroll in the Parc Micaud ⛲️ where the trees will welcome you with open branches 🌳. From a culinary point of view 🍽️, you'll take the opportunity to taste local specialties with, on the menu, Comtoise salad 🧀, potée 🥬, veal escalope 🥩, galette and the inimitable cancoillotte 😋.
Really, this trail is great, even very great! 💪
