From my personal life experience, wearing a ponytail is better. Because it is running, the exercise is also more intense. Long hair is definitely not good, it will be better to tie it up. If it is curly, the weight will be concentrated in one place, and it will inevitably shake when running. Therefore, it is more appropriate to tie a middle and low ponytail, and it is also more athletic. Of course, running is still based on comfort and practicality.
