No doubt Ian will expound at length, but just to give you some of the important points.
It isn’t basic as such, because the same skills instruction system could be (and is) used for total novice and world cup downhiller alike. Actually, when some very well know world cup riders have donw the course they learn it in exactly the same way. The system breaks riding down into component physical parts (eg looking (massive subject), footwork, body position etc.) plus psychological factors such as commitment and control and so-on. Also, the system takes into account personal and equipment factors such as bike set-up. Anyhow – one early thing to tackle is for you to understand how this all works, and how you can see your own riding in that context.
What you’ll work on is how to draw-out just a few elements at a time to build up a rider’s core riding posture (for example). Then you’ll be thinking about progression – how to take that static position and make it dynamic – this is when you’ll be thinking about exactly how the energy moves around to best/smoothest effect.
As the course progresses you will be encouraged to start devising your own session-plans to teach particular techniques.
Then you’ve got all the rest of it, to do with thinking about your rider’s level, caring for them and loads more besides. It will be quite a full two days.
I know you yourself ride to a high standard, but it would surprise me if getting into the system didn’t make you re-visit some elements of your own riding.
