I think its great news that you are able to successfully mock it.This is first time I have
seen someone telling me that they can mock captchas.Fantastic stuff.
Just to confirm it once again, how does your thread or jmeter script read the text and input
it in the input box given that for every hit, you are going to get different image with different
text in it.The path what you are trying to capture contains the encrypted image with text
in it.How are retriving that text ? 
As far as I know google captchas are not native JS + Image solutions, infact they are only
image with Text in it and this is single resource which is validated at server side with serverside
key(I think google gives you the key once your register for it.).
If you are able to mock it , you wanna talk to google and inform this.Its huge gap in their
What google recaptchas api does your app use, PHP/JAVA/JS or some thing else ?

@Oliver/@Kiran :

It is indeed Captcha

We are mocking this.

It works absolutely fine.
