RAF Regiment officer at 25?

Evening everyone.

So I have a current application in at the moment to become an RAF Regiment officer. I am very keen to get stuck in and I really want to get involved in everything from sports to hopefully pre-para. At 25 I feel the fittest, strongest and most mentally mature I have ever felt, which I am sure are good qualities for this role, however I am aware that some of my co candidates are younger. Is 25 too old and will I be at any disadvantages?

Thanks everyone in advance for your responses.
