Running is great, but running while defending a cause is even better! 🌟 This month of October, the Testathlon is making its big comeback. Lyon Sud Hospital 🏥 is mobilizing with the DigestScience Foundation and the hepatogastroenterology department (yes, we dare you to pronounce it on the first try 🥵) to organize a charity race benefiting research into digestive diseases and Chronic Inflammatory Bowel Diseases (CIBD) 💙. And they’ve thought of everyone ! Whether you’re here to beat your record or simply to enjoy the atmosphere, several formats await you: a timed 7 km, 14 km, and 21 km, as well as a walk of 5 km. With all that, you’ve got options 😁.
But the Testathlon isn’t just a race! 🏃 All day long, an activity village and awareness area awaits you, with plenty of surprises to help you better understand digestive diseases, meet the people involved in research, and share a friendly moment with participants and their supporters 🫂. Last year, nearly 600 runners came together for this wonderful show of solidarity. In 2026, they’re aiming even higher with an ambitious goal: double the turnout and bring 1,200 participants to the starting line! 🫨
So you can come with your friends, your family, well, as many people as possible, several distances are announced. We start strong with an "almost half-marathon" called "The Big Challenge"—a 21 km Lyon-style version 🔥, in a more-than-pleasant setting! Parc de Parilly will have you going up and down during your race 🏃, so we hope your legs are ready to handle the elevation gain! Otherwise, there’s a 14 km, "The Path of Courage," and you’ll need it for this top-quality challenge 💥. Around Lyon too—it’s always nice. Stopwatch running or just here to enjoy, "The Loop of Hope," 7 km in a nature 🍀 park, it’s always nicer to run surrounded by greenery. Walkers are invited too, a 5 km loop, "The Digestive Stroll," in the southern part of the park, amid trees and open plains! A great way to support the cause in a magnificent setting! 💖 Which company will take home the trophy for solidarity mobilization? ⭐️ Yes, you can come with your company to win the inter-company challenge 💼. Build your team and join the Testathlon race! 💪
A little Paris—that’s exactly how the city of Lyon is defined 🤓. Architecture inspired by the upper bourgeoisie, yes ma’am! 💄 There are must-see monuments to visit, so if you still have energy after your run, go for it! Notre-Dame de Fourvière, of course—this hilltop basilica that overlooks the city with a breathtaking view is a must 😍. And we told you it looks like the capital, so right next door you’ll have the Fourvière Metal Tower. Inspired by the third floor of the Eiffel Tower 🗼, it’s even taller than it: it peaks at 372 m thanks to its legs already being at elevation. Such a cheater…🤭 If you head back down a bit, stop by the neighborhoods of Old Lyon—you can’t get more typical than that! Old buildings, cobblestone streets, local shops 🌾 and above all Lyonnais bouchons on every corner 🤤. Food lovers will be well served 🍛. These legendary little restaurants keep Lyon’s culinary traditions alive, offering a simple menu at affordable prices 🤌. Honestly, what more could you ask for? 😜
So, ready to lace up your sneakers and join the movement? They’re waiting for you with bated breath, because at the Testathlon, every kilometer counts! ⭐️
A word from the organizer:
"We will be delighted to welcome you to this sporting and solidarity event dedicated to research into digestive diseases. Whether you are a runner, walker, amateur, or supporter, everyone will take part at their own pace and find their place in this day open to all. On site, you will find an awareness village with activities around digestive health, as well as areas to eat and enjoy the moment. The event is intended to be family-friendly and convivial, designed for runners but also for their supporters (because cheering... makes you thirsty and hungry)!"
For this 21 km course, you'll have the chance to run the 7 km loop, 3 times, to clock a Half Marathon (within 100 m)🤪!
Quick reminder: 7x2 = 14, yes indeed a double loop! You will validate these 14 km by completing the loop that is organized for the 7 km twice 🤗.
A loop with steep uphill trends 📈, but in a really pleasant setting 🤗.
A true labyrinth in the heart of greenery in Lyon 🌳. Starting right in the center of the park, you’ll gently head north. The climb hits from the very start of the route and you’ll go straight to the top ⬆️. You’ll be able to catch your breath a bit and start descending gently 📉 after km 2 in the Bois du Conseil Général. I hope you won’t get dizzy, because you’ll be doing quite a few hairpin turns in the middle of nature! 🔄 Near km 5, head east to take a real full lap of the park! At km 6, the finish is getting close 🏁; you’ll run alongside the Parilly Racecourse just before finishing strong at the 7th kilometer and coming to celebrate your great run! 🥳
Fancy a good digestive walk, 5 km in the Parc de Parilly? 😜 Get your shoes ready—this little loop will be hilly!
With a start in the middle of the park, you’ll be able to discover its southern part with a nice little walk 🚶. Setting off between the racecourse and the stadium 🏟️, you’ll be able to do loops through the middle of the park’s forest. At km 1 you’ll find yourself right at the bottom of the park 🌳, and little by little the climb back up awaits you. But slowly—we don’t want to scare you; you’ll go up in zigzags to make the climb easier to digest 🤗, so don’t panic. After km 4 you’ll start to catch sight of the racecourse in the distance, which you’ll head toward to finish in style 💖.
