Is 2:45am too early?

A strange question you might ask, especially if you are a "normal" sane rational person, who likes at least 8 hours sleep and can't cope with early mornings, whether they be extended nights or genuine wake ups.
Well generally I would class myself as the last person in the world to get up before 7am even with the mobile alarm clock known generally as Oliver.
So when (attempting to devise some sort of training plan to fit round work and family), I foolishly came up with the idea of an hours cycling before work on the days that Caroline doesn't work, I knew it may not be the easiest to implement.
However despite my doubts I have managed to drag myself bleary eyed into the early mornings quite successfully so far.
That is excluding the aberration when I set the alarm for 5:45 and then the elves came along whilst I was asleep and changed my clock by moving it forward three hours!
Hence the polite version of the question posed by Caroline, which I being a half awake bloke responded with, Are you sure that's what time it is? My clock says its 5:45!
The response involved turning the alarm clock off and coughing (or at least I think that's what she said I had to do!)
Never mind eh! Only another 174 get ups and all this training and riding will be over.

Maybe I had better start getting up at 2:45 after all!!!!!
