the best in the world for runners to train their legs

“You will encounter scenery that will leave an impression in your heart.” Naoko Takahashi (Runner)
You will encounter scenery that will leave an impression in your heart.
It’s warm even in winter, as if it were always spring in Izu Oshima. This island, which is famous for Oshima Camellia flowers, is a pleasant place to walk and run. The Camellia Road, which is lined with as many as three million trees of 500 species, is representative of Izu Oshima. When passing through the camellia tunnel, you will be embraced by comfortable warmness.
The Palm Road runs along the seashore. The sky changes its expression every day. When you go on this road while always feeling the wind from the sea, you can see Mt. Fuji showing its sharp form over the pine trees. In the evening, the sun is reflected on the sea surface to produce an extremely beautiful scene.
When you climb Mt. Mihara, you can clearly notice marks that were left by flowing lava. The ground has no grass. You can only see the sea and mountains that are not green, and you feel the threats of nature.
Various roads allow you to enjoy various kinds of nature. When you are tired of walking and running, you can revive yourself by bathing in a spa. Across the spa, you can see the Pacific Ocean spreading out. Izu Oshima is a place where you can encounter impressive scenery at any moment whenever you visit the place in any season.

“Road for Making Runners’ Legs” Yuko Arimori (Runner)
I think that this Oshima course is the best in the world for runners to train their legs. I have continued to use this course since training for my first marathon. This course is good to slowly train your legs on, rather than for sticking to a pace plan. You should go up and down gradually. You might feel comfortable enough to increase your speed on the flat sections but I think it is also important to check your running form and train yourself mentally sometimes. I believe that such training will empower you.
In particular, you should pay attention to the feeling in your knees while running uphill and the position of your legs when running down. The direction of your knees will become important when running up or down. You cannot tell their direction when running on a flat road. When getting tired, people tend to bring their bodies inward to try and hold out. Nobody will ever open out their legs when they start to get tired. On this course, you can adjust your running form by correcting the position of your knees while on the uphill. This course teaches you what to do when you get tired.
This course is very tough even for professional runners. You will be exhausted after running. However, this course is rich in nature, with the ocean on one side and lava landscapes on the other. Camellias, squirrels, and sometimes monkeys can be seen when running on this road. You can relax in a spa after completing your run. On a fine day, you will even be able to see Mt. Fuji in the distance.
