In order to drive like the pros, you have to train like the pros. Circuit race car drivers put in countless hours on the track, day in and day out, when they are in season. Even off season, they will practice 3 or 4 days a week, just to keep on top of their performance. Making sure to do the work with trainers, their mechanical staff, and having a great relationship with sponsors, is essential to ensuring that a circuit racer, and the entire team, is really going to do well at a big race, and ensure to come out on top.
So, when training, if you are looking to become a professional, and are an amateur, you must put in the time at the track to really perfect your driving style in the big race. You must make sure to study the track, the big turns and curves, the tricky corners of the track, and really get to know what you will be facing when it comes time for the big race afternoon. So, putting in the hours is the only way that you are ever going to improve your racing style, especially if you want to drive professionally.
