Large chainwheel in the Alpes of the Zwift

I started ZWIFT with an ELITE SUITO T yesterday: very good!
An issue today however: in the Alpes of the Zwift, even when slope was higher than 10%, I could stay on the large chainwheel while climbing with cadence 80-90 which seems not normal (not representative of real conditions at least). Would you have an explanation, a solution?
Thanks in advance

HI @Syriac_Bejaoui.

Welcome to the forum.

Check that you paired the trainer as controllable and power. Also check the trainer difficulty.

Hi Gerrie! thank you.
I indeed paired the trainer as controllable and power and could felt resistance variation from the trainer on more flat tracks. But I surprisingly had to stay on the large chainwheel in the Alpes…!
What means trainer difficulty?

Ok I just got it from the net.
What difficulty would you recommend for a “better feeling” of the slope?
Thanks

Try 100% and dial it down if needed.

great! thanks
I’ll try
