Newby - cadence vs Watt - resistance on the pedals


Wahoo kickr user here: just did my second training (started easy) but I had trouble doing the 90Watts during the relaxing phase of the training, the resistance was very light and my cadence was about 80 - 90. I had trouble doing 360 with the pedals and keeping a good troke.

I would expect to cycle at cadence 50, some more resistance and give the legs some rest?

At a certain point, I was doing 60km/h downhill… when I never went beyond 50 irl (I live in the Netherlands = flat as a pancake). In zwift i was on a on 6-7% downhill cycling very lightly?

Perhaps I am doing something wrong?

Hi Robert, are you familiar with ERG mode? Sounds like that is what you are experiencing.


Yup that must be it but in a possitive sense, I did not have the spiral of death but the spiral of light lol!

So what is bettr for a beginner? Use erg or not?

I was picturing myself climbing mountains in Zwift, having to change gears…

Workouts use ERG and that does not follow the route profile. If you do a free ride like you did in ride 1 you will feel the hills go up and down.


Your FTP might be set too low in that case. I generally slow my cadence down to around 80 during the recovery intervals and try to be above 90 on the harder intervals.

Exactly! The workout felt so strange! So when you a workout, start relex mode with cadens 80? And don’t usegears…

Next training sunday, thanks Gerrie/mike, will try that.

You don’t have to change gears, but it can be done.

So when you have a recovery block you can slow your cadence and the trainer will change the resistance.

As an exercise i did a training called the wringer, with a lot of short interval. I didn’t shift and it went much and much better.

I do have a challenge still with the relax fases, there sometimes the reststance is so light its hard to do 80 cadence.

Maybe i should do an ftp test in a week or 2
