This has probably been talked about in som form before, but i could not find anything when i searched…
I think it woul be a great idea to let zwift Utomaticly put you in the the race catagory you belong based on for example your best 20 min effort the last 6 months.
This would be great for the motivation since you could advance up in the catagorys
And it would stop wrecking your motivation when you race as a c or d rider and get hammered by riders that has joined as d rider but are really a or b riders.
And maybe have some system that put the lenght of the race in the description of the race. In km and mile.
Ride on !
