Time for physical preparation for CPC

I'm applying for an officer role (about to do my DAA) but I'm not physically ready to do the CPC yet. For context I'm 23M, in pretty good shape, I play a lot of sports etc, but I reckon I need a couple months to get my stamina and strength up to what I'd want it to be for the CPC.

Do you think I should just carry on with the application and get started on my training now, hoping that I'll have enough time, OR withdraw my application and only apply once I'm more prepared physically? I'm not very clued in on how soon the CPC would be (all going well beforehand) so just wanted to get a stronger gauge.

Cheers!
