Routes created by runners themselves

I recommend training in the grassy areas of the park which are full of trees, an idea I originally had after seeing some local runners running on the grass in another park and thinking to myself “Hmm, it’s possible to create your own running course on the grass too.” This has changed my perspective, and I have found that my nearby park is a wonderful training ground.
In summer, when everyone is in the pool, you can run on a shady cross-country course. I do everyday training on a cross-country course in Kazo Hanasaki Aquatic Park. This park has a wonderful atmosphere thanks to its abundance of trees—so many that a bird-watching group regularly holds meetings here—and with the large pool located in the center, it is a place that everyone can enjoy in their own way in summer.
The course I run is more than 2km long; it is a little difficult to describe, but it winds its way along in the shade, does a circuit around the lake and weaves in and out between the trees. There are also courses of 1km and 1.5km in length along the paved road, but the cross-country course is my ideal training course: the grass is very neatly maintained, the course is skillfully laid out to ensure that over 90% of your running is in the shade, it is kind on the legs, and provides your muscles with all kinds of training due to having just the right degree of ruggedness.
