The event in a few words

"And it goes on and on..." as our dear friend Francis would say 🎤.

"... it's just the beginning, alright, alright" : that's for sure! 😬 The starts won't be lacking, and you'll even miss traditional races, you know, the ones where you run continuously from start to finish ➡️. One starting line, one effort, one difficulty ... ahhh the good old days 🙄. The challenge of the Endurance Backyard 95 is much more than that. At a minimum, you'll line up for 1 start, but at a maximum for 48 starts 🤯. And all in one go, no question of taking 48 bibs 😂. The advantage is that you won't be alone in this jam: the 339 other participants of this edition will be wondering just like you why they signed up for this odd challenge 🤦‍♂️. Perhaps to explore the Val-d'Oise department, or simply to get some fresh air in this pleasant month of October, who knows? 🍂 But let's focus a bit on the race, we tell you more just below: 👇

The "Backyard", has nothing to do with the famous trilogy "Back to the future" (although you will have a rough idea of what your 48 next hours 🕰️ will be like), it is actually a running concept imported by our good old neighbors Americans 🇺🇸. Yes, when it comes to finding challenges that test the body and make you suffer for hours and hours, it’s often the country that gave birth to "Fast & Furious" and Dwayne Johnson to get all the credit 🎖️. Although we are not in the United States but rather in Taverny, in Île-de-France, the concept of the Backyard remains the same ✅. The idea of the race, brutal but simple enough, is to be the last runner standing 🧍‍♂️. All participants will start at 5 PM sharp for a supposedly "endless" race ♾️. From the start signal, you have 60 minutes to complete a loop of 6.76 km and 36 mD+, on a trail-like path 🌱. Once back at the camp, the time remaining on the 60 minutes is left for you to attend to your affairs 😴. But as soon as the second start is signaled, you need to be standing at the line again, and set off without flinching 😎. It seems easy when put like this, but over time, you quickly reach 161 km after 24 hours, the equivalent of a 100 miles event 💥. To avoid blocking everyone for an entire week (we know you have reserves), the organizers have here limited the race to 48 loops 🔁. This way, you're sure to set yourself up in your couch on Sunday evening by 7 PM, and start your favorite show 📺.

After spinning for 48 hours in the same spot, how about enjoying the surroundings a bit? 🤩 This nature race that takes its start in Taverny is surrounded by forests, castles, and watercourses 💦. Perfect for a change of scenery and extending your stay in the area. Now that you know the Bois de Boissy like the back of your hand 🌳, why not tackle the vast Forêt Domaniale de Montmorency 🪵. With the many wonders it holds, the best option is to go without a specific plan and let yourself be carried by its features: 😋 ponds, viewpoints, streams, castles 🏰, fountains, or even stables set everywhere in the forest 🐎. You’ll see: it’s a bit like a treasure hunt, but you do not yet know what the final treasure 🎁 is. And if you really want to put yourself in the shoes of a brave adventurer, you can always come disguised 🥸. Just a few kilometers away, you’ll also find the Château d'Écouen, a true Renaissance jewel 💎, perfectly maintained and accessible for visits. If stars interest you more than old bricks 🧱, you can also head towards Le Bourget in less than an hour by car 🚗, to discover the Museum of Air and Space. Your few miles covered previously will seem infinitely small compared to the size of the universe 😳. Finally, for our budding artist poets, the Van Gogh House is just minutes away heading toward Beauvais, more precisely in Auvers-sur-Oise 🧑‍🎨.

So if you are looking for a new sports challenge, come face the Endurance Backyard 95 at the end of October 🍁, and you'll see your heart go way beyond 95 bpm 🫀.

4 reasons to join this race

Know the neighborhood like the back of your hand 🛍️
By going around in circles, you can be sure no detail will escape you. You can name the plants and greet the locals 👋. It's almost as if you grew up here. The only thing to be wary of is not losing track of time: you're engaged in a race after all! 😅
A good excuse 🗣️
In this event, 99% of participants do not finish and are marked as DNF 🏁. So you'll have all the excuses in the world to say you didn't conquer the Endurance Backyard 95 monster. And if you're the last one standing, you can always say you knew it 🏆.
A race at your level 💪
You choose if you want to continue, but you also choose when you want to stop. For this, it's very simple, you just need to stay comfortably seated on one of the camp chairs 🏕️. The advantage is that everyone can run together, and at their level 👌. If you're looking for competition, you just need to keep going, but if you want to commit just for 2 or 3 laps, you can do that too 😉. Here, everyone manages their own race!
A psychological battle 🧠
More than a simple sporting event, the goal is also to mentally weaken your competitors. During the first 10-15 loops, everyone is friendly, but wait, as you'll see it will start to become a bit competitive, like "will you break before me?" 👀, "do you have any juice left?" 🧃, "I'm the strongest", and that's when you have to know how to be strategic ♟️. Play on fatigue, simulate a burst of energy, or deliver the final blow when least expected: it's a race won with your head as much as with your legs 🦵.
