About the Event

Experience the thrill of running through breathtaking terrain at the "High Plateau" Marathon, where runners will navigate both the iconic flatlands of Tainai and its legendary steep slopes. This challenging course offers a unique blend of elevation changes that test endurance while providing stunning views.
The event starts on the expansive plateau known as Tainai Plain, offering participants an initial stretch of relatively flat terrain before transitioning into sections with significant inclines. The route winds through picturesque landscapes, showcasing local flora and fauna along its path. As runners ascend and descend various hills, they will encounter several steep ascents that are a hallmark of this challenging race.
In addition to the main marathon distance, there is also a shorter fun run option available for those looking to enjoy parts of the course without committing to the full challenge. Both events cater to different levels of experience and fitness, ensuring an enjoyable yet demanding day out on the trails.
Registration fees are set at 4500 yen for adults participating in the marathon (3500 yen for the fun run), while high school students pay 3500 yen and middle and elementary school runners can enter for 3000 and 2500 yen respectively. This inclusive pricing structure aims to make the event accessible to a wide range of participants, from seasoned marathoners to young athletes.
Join us at this exhilarating race that combines scenic beauty with rigorous physical demands, making it an unforgettable experience for all who take part.
For those seeking both picturesque scenery and challenging terrain, the "High Plateau" Marathon offers an unparalleled opportunity to test your limits while immersed in Japan's natural splendor.
