I’ve been using Zwift since launch, have over 10,000 miles on it. In the past, I was racing in A category races because my w/kg was in the low 4’s . Due to a Covid infection (I’m a long-haul suffer, yes it exists), I’ve not been able to ride at the same intensity. I’m gradually getting back into form. I’ve been racing in the B races recently since that seems way more appropriate and my numbers are more in line with that 3.8-4.0. I’m not sure I really understand classification since it can vary so much. I’m also 59, so there’s that too, but I’m not going to let age slow me down.
Is it generally accepted that you can downgrade yourself ?
