5 minutes

5 minutes isn't a long time, but it can seem like a lifetime when you are hurting.

Managed to pump out a few 5 minute intervals at my FTP of 300w. Not impressed? Yep, neither am I. But to add some flavour I did this 8 times (with 2 minutes z1 recovery in between) all on my brand spanking new time trial machine pictured here:

Managed to get through the first 6 intervals without much effort, but interval number 7 and 8 sure did hurt. Adapting to my TT position has been pretty straight forward, I'm in a comfortable position which is the most aerodynamic i have ever been, my effective head tube height is 12cm, i'm sure with some more time I can get down to the top of the head tube which is 10cm. 

The only thing I'm bummed out about is that I don't have a set of race wheels with a powertap installed. This is where crank based power measuring has its advantages as your not locked into one wheelset. This means the time trial next week will be on race wheels, and i'll be judging my effort levels with heart rate and perceived exertion. My interval training will help me judge my perceived exertion and hopefully i retain some muscle memory of what 300w feels like.

Time (no pun) will tell!
