Running at night is good. There are two kinds: one is running before eating, usually around 5 pm, and you can eat after taking a shower; The second is to run after dinner, eat dinner early, run again after an hour, take a bath after running, and have a good sleep at leisure.

When to run has been said above. You can do it according to your choice, but it's not too late. I don't think you should exercise after 9 pm. If you just exercise, the longer you run, the better. It is generally recommended to run for more than 40 minutes and less than 60 minutes. Of course, your previous run can be about 30 minutes. I can control the speed of running by myself, and I don't need to run too fast. I feel a little hard, but I can still stick to my best.
