Show them the current "top" swimmers rankings from their teens.
They weren't making nationals at 13/14/15.
Our club do a change of the way they train. They chose lanes generally for warm up and they swim with their friends. Usually stay in those lanes for tech sets.
But they also do loads of separate training so they'll be split as a session will have LD, form and sprint all happening alongside each other and in each of those 2 lanes they'll be set into groups dependent on if they are all doing same time or different. If all on same time coach often puts them into fastest 2 next fastest etc so each lane decreases in swimmers speed but each lane has a swimmer next door who they can pace with etc.
But other than that their coaches just encourage everyone to train hard and set each swimmers journey dependent on what their next aim is. For some it's regionals and others it's nationals. For others it's going back to nationals.
One of the reasons ds is doing our regionals is for the social side. No one is expecting him to swim well or fast because it doesn't fit into his programme for that. But there's a team spirit whereby DS doesn't feel he needs to excel to be included or for positivity.
But I think it's also easier for ds because no one expects him to go as fast as everyone else 🫣 😂
I understand the frustration. I'd hate for ds to be in an environment whereby achievements outway the training ethic. I guess maybe we are lucky that his club aren't like that?
