Hi, I started using Trainerroad in November with my Tacx Neo.
I am 90kg and I do timetrial competitions.
Before having the tacx trainer I did a lab ftp test (with a mask for VO2) and my ftp resulted to be 409w.
Previously, on a time trial competition (25 minutes), my average power had been 455w while the NP was 472.
I did my first ramp test using trainerroad in November and the value was 337
In a later ramp test, after starting training with bicycle twice a week, the result of a further ramp test using trainerroad was 345w.
One month ago I have done the trainerroad 8 minutes ftp test and the result was FTP=370.
Hence I am using this value (370w) as my FTP in the trainerroad workouts.
Using this value the workout is really hard: for example I recently have been doing the Dardanelles workout and in the beginning I could stay over 85 rpm. In the last part my average rpm was 72 and my average heart rate was 173. (in the race I mentioned above my average heart rate was 172 and my rpm was 87).
So, my questions are:
- Is it normal this big difference between these FTP values?
- Which FTP value should I use?
Thank you in advance for anyone who can give any answer to this.
