Learn English – Mile or miles? Singular or plural

plural-formssingular

Could you explain me please, why sometimes the word "mile" is used in singular, sometimes in plural, while in both cases it refers to several and not 1 mile.

Example:

They took part in a 26 mile long swimming race.
After 12 miles he got tired.

Thanks in advance to those who can enlighten me!

Adjectives in English do not change according to the plurality of the word they modify. So it will be mile if it is used as an adjective, which it is below.

They took part in a 26 mile long swimming race.

It would take plural form if it was a noun.

I ran for 26 miles.

However:

The race was 26 miles long.

To be, being a copular verb, is special, and I think what's happening here is that 26 miles is a predicate nominative and long is technically an adverb modifying was.
