There's more than just asphalt in Île-de-France, and that's what you'll discover if you participate in the EcoTrail of Paris! The capital opens its doors to fans of responsible sports by offering 9 different distances. So grab your tickets because you are sure to find the distance you need 😏. Yes, you can choose from 7 trail distances (120 km, 80 km, 45 km, 35 km, 30 km, 20 km, 10 km) and 2 Nordic walks (20 km and 10 km). Isn't that great? And you haven't seen anything yet... First, wait to cross the numerous parks, woods, stroll along the beautiful Seine and climb the floors of the Eiffel Tower 😍.
Even though it is clear that the Iron Lady, the Champ-de-Mars and the monuments historical are the stars of the various races, know that you will especially have the chance to enjoy an exceptional natural setting 🌤. Indeed, if you are not familiar with the concept of an EcoTrail, it involves using preserved natural trails to raise awareness among runners and the public of the fragility of the environment. The goal of such a competition is essentially to raise awareness of the climate emergency through an awareness campaign 🤝. Thus, every waste is sorted and collected, trails are cleaned, and the products used are sustainable, local, and seasonal... Mmmh, that makes you want to frolic in the forest, doesn't it? 🍂
But enough about the concept, let's talk about the trails! The race starts will be held in unusual places. Drum roll... 🥁 You can choose from the terrace of the Paris Observatory in Meudon (which is generally closed to the public, what a chance you have!), the Ile de Loisirs de Saint-Quentin-en-Yvelines, the Domaine du Château de Versailles or the Domaine National de Saint-Cloud... 😯 Enough to make you sing the Marseillaise at the top of your lungs as you visit the emblematic places of our heritage 🎙. In fact, the highlight of most races happens to be the Eiffel Tower itself, lucky you. But the races are primarily in nature, composed on average of 85 or 90% green spaces.
So, what motivates you the most? Nature, monuments, or environmental commitment? Whatever your answer, the EcoTrail Paris will satisfy you. So break the monotony of Parisian life and the adage 'metro work sleep'. You won't be disappointed once you understand that it is also pleasant to stroll in the region without suffocating while enjoying its splendid natural spaces! 😄 After your race, we invite you to linger longer to explore more of the city of light and its surroundings 🥐.
When Paris wakes up, Paris is green! 🟢
