I bought my first bike (a traditional road bike) almost a year ago and a Wahoo Kickr Core a few months later. I used Zwift to do most of my training. Three months ago I finished my first 70.3. At that time I had an FTP of 300 on my road bike. I took about 3 weeks off from training after the race. I did some light training for the next 6 weeks; nothing serious. Just putting pressure on the pedals, however, I was still using my road bike on the trainer during that time.
I did an FTP test 3 weeks ago and my FTP was down to 230. Would it be normal for it to decrease by that much? I did a spindown calibration before the FTP test on my Wahoo.
I will also add that during that easy 6 weeks of training I bought my first TT bike. I used it for that FTP test I did 3 weeks ago. I’m sure it does make a difference switching from a road bike to a TT bike in your FTP but I certainly wouldn’t think it would be that much of a difference, right?
Lastly, I am doing the 12 week FTP builder program and it is using my latest FTP of 230 to structure the workouts. I am now on week 4 (using the TT bike) and it is really easy…like my HR isn’t hardly getting above 140 on the “hard” workouts. Should I set my FTP higher? Keep it the same? Redoing the FTP test would probably be ideal but I want to avoid that if at all possible until I’m done with the 12 week program.
Thoughts?
