about the race

Now in its 24th edition, the Osaka Yodo River Citizens Marathon (or as we call it unofficially, the Osaka Yodo River Citizens Marathon and Half Marathon) takes place almost entirely along a riverbank. Having skipped the 2020 and 2021 editions due to COVID, the race organizers are ready to welcome runners back after three years!

This is a great warm-up for Japan’s marathon season and is easily accessible by public transportation from downtown Osaka and Kyoto. Both distances are out-and-back with very little elevation. While most of the course is on road or sidewalk, some segments are of varied terrain, including gravel, pebbles, and dirt.

Since 1997, the people of Osaka have come together to host this event for women and men of all ages to enjoy. This year, entry is limited to approximately 7,000 in the half marathon and 6,000 in the marathon respectively – entries close once maximum capacity is reached. A late 9am (half) and 9:40am (full) start will assure runners plenty of time to fuel before the race and stake their spot at the start line. 

As per usual in the past few years, Naoko Takahashi will be present on race day. A former national elite runner, Ms. Takahashi was the first woman from Japan to win a gold medal in track and field during the 2000 Sydney Olympics. She was also the first woman to break a then-world record to win the 2001 Berlin Marathon.
