How much practice?

[jsw123]

As a newbie, albeit I did race a Tamiya Boomerang a few times 25 odd years ago, how many times should I try and practice at my local track?

I was blown away with the speed of my 22 and found racing pace almost impossible to maintain. Apparently Eden Park is quite a technical track but I pretty much had to 'coast' to get round without wiping out.

I'd love to know how people got to the standard they're at and what sort of goals I should be setting for myself?
