I assume you will participate in the competition (“have” is ambiguous).

I have an English competition tomorrow, so I won’t be writing today. I'm going to participate in an English competition tomorrow, so I won't be writing today.

These are ways I would say this. If we already know something is going to happen, we usually use "have" by itself: I have school tomorrow. I have a test tomorrow. I have a volleyball game tomorrow. The two verbs we often use for competitions are to "compete" or "participate in."
