Think that has always been a major factor with juniors and young riders.Thought the likes of Stead and Co would give the info.Another point you make that is really valid is track prep all the years I have watched speedway the second half riders only have had slick tracks to race on and generally learn nothing,years ago when there was more dirt on the track if they ever got into the Team in a Reserve Position they were out in Ht2 and usually got into all sorts of trouble as there was dirt on the track which they had seldom encountered.Like you say track prep should’ve the same as league meetings,it’s the only way they will learn(the hard way).The Poles have recognised Trainers for all their youngsters, which would take the pressure of parents like yourself.We talk a good story, but do we deliver!! Best of luck to your son,tell him just to enjoy it and it will happen.
