It's Christmas early! 🎅 Want to know why? Because in your exceptional runner's advent calendar, a new challenge has been added that will make you drool 🤤 just as much as a delicious Kinder Bueno! 🍫 Plus it's a big novelty, let us introduce you to the first edition of the Ultra Trail Grand Colombier! 💪 To mark its emergence in the highly sought-after world of sporting challenges, it offers no less than 6 distances 🤩. And all this for absolutely everyone, so let yourself be tempted by a new adventure! It will also be an opportunity to visit the department of Ain, as the event has settled in Culoz in the region Auvergne-Rhone-Alpes ⛰️. It's an escape into the heart of nature in the mountains featuring, as the highlight, the col of Grand Colombier 🔥.
Among the 6 proposed courses, their differences are their strengths! The Ultra Trail Grand Colombier starts small, with a 10 km trail designed for a little guided tour of the city of Culoz! 🏘️ The race levels up slightly with the 16 km course while still remaining accessible with a flat track along the Rhône. We continue with a 30 km which begins to require some experience to participate! 🎽 It will make you discover the famous Grand Colombier, while exploring the breathtaking surroundings. But let's move on to the distances only experienced runners can aim to conquer! 👣 The marathon distance, 45 km in the heart of the Bugey, located at the Jura border 🏞️. But wait, passionate enthusiasts can also try to take on the challenge! 🤠 Just avoid arriving for this kind of challenge without training; we see you coming, tourists! 😉 Now, runners eager for adventures will feel involved 😅. It's the Ultra 80 km that opens the floor for great trails! With 3,000 meters of positive elevation 🤯 on this demanding course through dizzying valleys! 🌿 If you're dying to participate but feel that the 80 km might be a bit too tough for you, you can always register for the relay of 3! 🤝 To crown the event 👑, the Ultra Trail Grand Colombier owes its name to the impressive Ultra 120 km! 🔝 Across ridges, forests 🌲, lakes, and waterfalls 🛶, if you take this path, it's truly a blend of all the most beautiful sceneries in the region! With a total of 5,000m D+, it will require determination, patience, and courage! 🤓 This adventure is also offered in a relay of 5, allowing less experienced runners to enjoy such a spectacle 😇.
So yes, at this point, if you can't find satisfaction with the Ultra Trail Grand Colombier, here at Finishers, we're going to run out of ideas... 💡 But if we can keep convincing you that this event is made for you, we can give you a little taste of what happens after the race! Because those who love the effort also love the comfort 😏. For the runners of 120 km and 80 km (outside relays), a nice little dish awaits them at the end of the race to regain some strength! 🥘 They will need it! Once everyone has regained a little health ⚡, a small party is organized to celebrate these great achievements! 🎊
If you're planning a little stay, then let yourself be tempted by some activities. You could, for example, take a refreshing dip at the Lac du Bourget 🏊♀️, which is only 30 minutes away ⏱️, also ideal for a family or friend walk (alone is fine too!) 🤪. If you want to enjoy a moment of peace and relaxation directly, we highly recommend visiting Belley 🥰, a charming historic town with rich architectural heritage 🙌. If your thirst for adventure is still not satisfied, then take your car 🏎️ (or carpool) to the Grottes de La Balme and explore this impressive natural site, you might discover some relics of the past (oh come on, we've all dreamed of being archaeologists)! 📜
So what do you think of all this? Only you are missing to make it all perfect, right? 😎
Have you decided to take on the BIG challenge? Then we hope you are well prepared because 120 km is not a piece of cake!
You will start from Belley at 3:00 AM 😴. The first refreshment station is at Conzieu, at the 15th kilometer (in water) 💦. Then you will head to Lac d'Ambléon at km 25.5, which is also the first relay point of the race, it's also an opportunity to grab a bite before heading back 🍫. You will then pass by the Innimond viewpoint at the 31st km before continuing the stride to Contrevoz for your 4th refreshment. You will (finally) be halfway through the stage when you reach the Sérémond viewpoint (Virieu le Grand), which is at the 60th km. We advise you to gather your strengths for the climb towards km 77, where you will have a slight descent before starting the high elevation section! 🤯 At Lilignod at the 90th km, you will begin the ascent towards the Grand Colombier! Another small descent at km 100, and the serious stuff begins 10 km later, the climb of the pass! Once at the top of the Col du Grand Colombier, there are (only) 14 km separating you from the finish line! 🏁 Fortunately, to reach Culoz, it's all downhill! 🤩
This way to the relay! 😎
Prepare well for the 80 km Ultra challenge with its 3,000m elevation gain!
Starting point at Contrevoz ! Join the Belvédère de Sérémond (Virieu le Grand) at the 13.5 km mark! Then enjoy a downhill stretch until the 2nd aid station 🥤, at the Hauteville Plateau, 30.5 km. A beautiful ascent awaits to take you to Lilignod, 42.5 km, then a nice downhill to the Chalet d’Arvière, 54.5 km. You'll need to be courageous because the most challenging part starts from there. To reach the Col du Grand Colombier 🔥, you will have to climb about ten km! Once up there, it's bliss, a dizzying descent to the finish line, which is in Culoz! 🏘️
