Sentence Fragment? "The [adverb] [noun] [verb], the [adverb] [noun] [verb]."

I apologize if this has been asked before, but I cannot find a clear answer.

I am analyzing a statement and attempting to determine if it is a fragment or complete sentence. This is the general idea of the structure:

-The faster I ran, the stronger I became.

-The harder the wind blew, the colder the air felt.

-The longer I looked, the more confused I was.

The [adverb] [subject] [verb], the [adverb] [subject] [verb].

Is this sentence structure considered a full statement, or a fragment?

It has a subject and a predicate. There's a noun and an action the noun is "doing". So, yes, it's a complete sentence.
