Meaning of adverb followed by まで


> 専門家などは、このミサイルはアメリカに届く **ぐらい遠くまで** 飛ぶと考えています。  
>  Experts think that this missile will fly _far enough to reach_ America.

I've never seen まで used with an adverb before. This translation is my best
guess. Extrapolating from my guess I made this sentence:

> レースに勝つぐらい速くまで走る。  
>  I will run fast enough to win the race.

Is this a natural sentence and does it mean what I think it means? Would this
construction be used in everyday speech? If not, how would I express the same
idea?




> 「専門家{せんもんか}などは、このミサイルはアメリカに届{とど}くぐらい遠{とお}く **まで** 飛{と}ぶと考{かんが}えています。」
>
> Experts think that this missile will fly far enough to reach America.

Your translation is just plain good here if not literal.

It is, however, incorrect to translate:

> I will run fast enough to win the race.

to

> 「レースに勝{か}つぐらい速{はや}く **まで** 走{はし}る。」

The use of 「まで」 is incorrect here.

「まで」 can only describe a _**physical distance**_ when combined with 「遠く」 and
followed by a verb like 「走る」, but this sentence is all about a _**velocity**_
and not about a distance.

Thus, the correct way to say this would be:

> 「レースに勝つ(or 勝てる)ぐらい速く走る。」

Using 「勝てる」 would be slightly more natural.

Finally, you stated:

> "I've never seen まで used with an adverb before. "

「遠く」 here is a _**noun**_ meaning 「遠いところ」.

「名{めい}」 is short for 「名詞{めいし}」, which means a "noun".
