Every year, between the end of March and the beginning of April, the Trail of Josas takes place in Yvelines. The town of Jouy-en-Josas, in Île-de-France 🇫🇷, opens its doors to the Vallée de la Bièvre (⚠️ not to be confused with the "Vallée de la Bière" 👀). Just about twenty km from Paris, you’ll be able to taste a bit of [DEL: hops :DEL] nature away from the hustle and bustle of the capital 🍃.

We hope you have been good this year because Santa 🎅 won't be far from chasing you on the trails of the Josas Fireflies before his big annual tour... 🎁 It's in December, during the Christmas market of Jouy-en-Josas that you'll start this night race 🌙 promising you an extraordinary experience. The Josas Fireflies is the race where fireflies compete with shooting stars 💫. Whether you choose the trail of 8 km or 12 km, you'll run lighting up the gentle forest landscape of the Yvelines, so make sure to choose your costume wisely to shine brightly! 💡 Yes little firefly, to shine there's nothing better than neon! The dress code is stabilo 🖍️. At least, you won't get lost in the dark! 😉
