Haha, I have no prep. I am a super newbie. Only started riding last spring. However, I have a secret wish to compete in a TT. I did the local route last year for the first time on my own and was only a few minutes off the young girl's times (the slow ones that is and only 1.5 minutes slower than dh. I'm sure with some training I could do ok in my age group (46). Not sure if there are any women my age who race though. Might make for an easy win eh?

So, in answer to your question, my training looks pretty like what you just outlined for me
