Have you always dreamed of running in the Land of the Rising Sun? 🌅 In September, pack your bags 🧳—we’re inviting you to Japan 🇯🇵, in the Osaka Prefecture, in the Yodogawa district for the Yodogawa Ecomarathon 🏃♀️.
If you’re more of a solo type 🧍♂️, come run the half-marathon or the timed 10 km; if you’re more into family running 🧑🧑🧒🧒, a parent-child 5 km race is organized. The races will start at exactly 11am 🕚, in the heart of Osaka, along the Yodo River. You’ll follow its riverbed via the bike path 🚴♂️. As the route is flat, easy, and fast ⚡️, the race is open both to novice runners and seasoned runners looking to beat their personal record 💪. With a participant cap of 300 people, you won’t have to elbow your way through at the start 😝.
Alongside several other sporting events organized, particularly in the prefectures of Saitama, Osaka, Hiroshima, Kyoto and Kumamoto (but mainly in Tokyo 🌸), the Ecomarathon positions itself as an organization concerned about the environment 🌳 and committed to various causes 🎗️. This year, it is possible to donate to the international refugee support organization : Second Harvest Japan. As Japan’s first food bank, the organization is committed to ensuring that everyone has access to food 🍲.
The city of Osaka has a complex history, but has managed to evolve and reinvent itself over the years while maintaining its importance as a central and important city in the country. It is a very touristy destination that combines traditional and modern culture 🎐. Whether you're interested in gastronomy, shopping, culture, or entertainment, you should find what you're looking for in Osaka 😍. If you choose to extend your stay, why not visit the Shin-Osaka Station Museum to learn more about the trains that connect the prefecture. If you're looking for 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 answer all your questions 🧐.
So, tempted? Book your ticket ✈️, lace up 👟—we’ll be waiting for you at the Yodogawa Ecomarathon 🎏.
