I am using trainer road yes mr blobby.
I felt the same – I got on the bike and it all felt too easy, I literally checked everything – trainer, bike, FTP settings weight, pressures….
I’m now thinking that before something was wrong with the bike because I’ve been struggling for a month coincidentally after my FTP had gone up. I asked a few questions and concluded I’d had a performance drop due to tiredness it was literally a struggle to get started. My warmup was at 120bpm, now it’s 105. Despite all that was improving weekly on my mtg series races. I lowers my FTP by 5% manually.
But I would have noticed if something was rubbing. Perhaps the trainer roller was resisting? Could the hub or BB have caused resistance? And therefore have I been banging away for a month against some extra resistance and now accidentally feeling stronger as a result?
Confused!
Edit : wyinkin- yes I’ve had colds – recovering from one now actually. But even if I was carrying a virus would it make a difference overnight.
Edit again: I did start taking a multivitamin a week ago, hmm…
