highlight consecutive duplicates only if they repeat a specific number of times

Is there a way to count only when the data repeats a certain number of times in a row? For example, I need a formula to highlight cells only if the duplicate value occurs 30 or more times consecutively.
I have been using either "=COUNTIF(A1:A3,A2)>1" or "=OR(A2=A1,A2=A3)" in conditional formatting to highlight all consecutive duplicates. However, I have been unsuccessful in modifying these formulas to only highlight consecutive duplicates that occur 30 or more times in a row.
