There’s nothing wrong with having coaching. Had I done so in the past I think I’d have improved a lot more quickly.
I was always reasonably quick(at a weekend warrior level) and fairly confident on trails, but a bit too erratic and gung-ho with it. The standard of my riding stagnated for a long time.
For me, learning to ride a motorbike and become better (Improving smoothness, control, relaxed grip, concentrating on observation etc.)at it prompted a renewed interest in mountain bike technique.
-I would definitely recommend the Mastering Mountain Bike Skills book.
I like a rough, tight or fast, technical trail, I’m fairly happy with drops and I’ve recently become more comfortable with jumping, although there’s a long way to go.
