According to the information you provided, I have a cold and a bad cough, and I will do strenuous exercise tomorrow. First, I am afraid that I will be exhausted after catching a cold, and I will have a fear of the outside world. I will catch a cold again after running, which will aggravate the cold.

Guiding opinions:

Suggestions should be based on your situation. If you don't have a fever, general weakness or soreness, you can attend. If you feel exhausted, you should discuss with the teacher and try not to participate. If the heart is bad because of strenuous exercise, it is quite dangerous.
