If you W/KG is > than 3.1, then you will be categorized as B.
It has nothing to do with how well or how fast you race.
Not all B riders are faster than C riders.
Unless you are in a Handicapped race (Hare & Hounds) or a race where you don’t see the other classes, you can still race and draft off the C riders but you will be identified as a B rider.
The category of ABCD has nothing to do with your in race experience or performance.
You will still be with the same riders and the faster, stronger riders will be ahead and the slower, weaker riders behind you.
Just love the one you’re with and race them too!
You should be aware, regardless of you well or not you think you do in a B race, the race community feels you should register for the race category that is indicated by your W/KG.
We know it is not perfect and we are hoping that a new system will come along soon but the community is begging for Zwift not to allow people to sign up for races below their W/KG.
You have a valid experience and I am sympathetic to you. I will soon be kicked out of C too.
That’s the rules - for now.
