The event in a few words

Have you always dreamed of running in the Land of the Rising Sun? 🌅 In March pack your bags 🧳, we invite you to Japan 🇯🇵, in the Osaka Prefecture, in the district of Yodogawa for the Yodogawa Ecomarathon 🏃‍♀️.

If you're a solo runner type 🧍‍♂️, come run the half marathon or the 10 km timed, or if you prefer family running 🧑‍🧑‍🧒‍🧒, a parent-child race of 5 km is organized. The race start will take place at 11 a.m. sharp 🕚, in the heart of Osaka, along the Yodo River. You will follow its course via the bike path 🚴‍♂️. The course being flat, easy, and fast ⚡️, the race is open to both novice runners and experienced ones looking to beat their personal record 💪. With a limited number of 300 participants, you won't have to elbow your way at the start 😝.

With several other sports events organized, particularly in the prefectures of SaitamaOsakaHiroshimaKyoto and Kumamoto (but mainly in Tokyo 🌸), the Ecomarathon stands as an environmentally conscious 🌳 and committed to various causes 🎗️. This year, donations can be made to the international refugee support association : Second Harvest Japan. As Japan's first food bank, the organization commits to ensuring everyone has access to food 🍲.

The city of Osaka has a complex history but has evolved and reinvented itself over the years while maintaining its importance as a central and important city in the country. It is a highly touristic destination that combines traditional and modern culture 🎐. Whether you are interested in gastronomy, shopping, culture, or entertainment, you should find joy in Osaka 😍. If you choose to extend your stay, why not visit the Shin-Osaka Station Museum to learn more about the trains connecting the prefecture. If you seek a bit more tradition, don't hesitate to try the Sentō (public baths) or Onsen (traditional hot baths). To learn more about Shinto culture, the Kazaki Shrine ⛩️ will provide you with all the answers to your questions 🧐.

So tempted? Grab your ticket ✈️, lace up your shoes 👟, we're waiting for you at the Yodogawa Ecomarathon 🎏.
