classes stand as is.
If we cut to just ages we wont have enough to cover the classes and there will be less rides, so everyone looses.
If you don't want to as you say fight it out with some young guy then FFS just stay out of his way and just tootle around as apparently want to do, I don't see the issue there, (other than self interest or pride).
PLEASE DONT USE THAT AS AN EXCUSE FOR WHY YOU ONLY WANT TO RACE WITH YOUR PEERS. you can race your peers with any bike you like in your age group, you can even wear a plant pot on your head for all I care.
If you think some young guy is going to get in the way in the class where we are showcasing a bike class then please... wait 5 secs and then leave the gate, its prity simple really. IF its about fun and your mates as you say then you will be there any way, please stop creating divertions.
