So i’ve trained exclusively in ERG since i got into cycling 4 months ago. I thought being able to maintain these watts without thinking and without being able to back off would make me progress much quicker than in normal resistance mode…
It appears i was wrong.
Anyway, i went into zwift to try and ride in group for the first time. I tried to maintain the same watts consistently and found it a real struggle. What i could do for 20min sweet spot intervals in trainer road ERG was significantly harder to maintain in a normal resistance ride for just 10 mins, i just couldn’t do it. My power was spiking all over the place and it brought my average down a lot. The result was a significantly hard time and quite a low average power for the ride.
Anyway, i decided to record a training ride in TR with ERG mode, and use a power metre to record the same ride and see what i was actually putting out.
Here is the comparison.
As you can see, my power metre (up top) shows really large spikes, going down to 76 watts and then up to 250+ consistently . It appears i cannot maintain proper force on the pedals or keep power in a tight spread. This is why i believe i have a hard time actually maintaining constant power in normal rides. Has ERG given me a really false sense of training?
I know there is power smoothing, but i didnt think the difference would be this large.
So what do i do?
A) Lower FTP and do rides in resistance mode, learning to actually maintain required output
B) Just carry on with ERG and realise these numbers are really inflated
C) Look at my pedalling and learn how to apply power more evenly? Whats the best way to do this
Any thoughts here?
