do any categories other than A’s win these types of races?
Yes, I’ve ridden as a B and C and won. It depends on the gap, they adjust it now and again. For example if C hold off A by a couple of minutes they’ll get less of a start next time. Also it’s also down to riders on the day. If A isn’t particularly strong or coordinated then they may not take it.
thx stuart guess ill give it another try in the future.
Look around as there are several variants. Cat & mouse is another.
