The event in a few words

Have you ever dreamed of running in the Land of the Rising Sun? 🌅 Well, here's the perfect opportunity for you! 🫵

The Tondabayashi Ecomarathon, located in the beautiful city of Tondabayashi, in the Osaka Prefecture, in Japan 🇯🇵, is a must-attend event for any runner 🏃‍♂️. This road race takes place in May 🌞, offering 2 timed races ⏱️ of 5 km and 10 km. Whether you're a beginner or experienced, you'll have the opportunity to run along the bike path that runs beside the Minamikawachi bike path 🎣. If you're here for a family day, a 5 km parent-child race 👩‍👦 is organized. In any case, you'll start at 11 AM, and since the races are limited to 200 participants in total, you won't have to worry about being trampled when the race starts 🤓.

With several other sports events organized, particularly in the prefectures of Saitama, Osaka, Hiroshima, Kyoto, and Kumamoto (but mainly in Tokyo 🌸), the Ecomarathon places itself as an environmentally friendly organization 🌳 and engaged in different causes 🎗️. This year, you can donate to the international refugee support association: Second Harvest Japan. As Japan's first food bank, the organization is committed to ensuring everyone has access to food 🍲.

If you plan to extend your stay and visit the region, Osaka Prefecture is full of attractions for young and old! The Kaiyukan Aquarium is one of the largest in the world, housing a wide variety of marine life 🦈. The Universal Studios Japan are the first to have opened outside the United States, similar to those in Orlando, and have been introducing exclusive attractions for a few years, so you can find manga heroes 🫰 and popular Japanese characters. If you only have one day in the prefecture and don't know what to choose, why not go on an excursion to the city of Kyoto, former capital of Japan and an iconic place of traditional Japanese culture 🎏.

Today, Tondabayashi is a historic city with a strong religious past reflected in its architecture🎐. In the very center, about 250 of the approximately 600 townhouses have remained traditional houses, like the former Sugiyama residence, located southwest of the city, an important cultural heritage listed at the national level! 😍

So, ready to take on the challenge? Warm up, tie your laces, and rush to sign up for the Tondabayashi Ecomarathon! 🚀
