yeah, don't be intimidated by the banking. As deft says, it's just as steep at the bottom as at the top and you'd be surprised at how slow you can go without slipping.
My tips might be not as you expect.
It gets quite warm, wear gloves, take clean clothes and a towel, take a water bottle. There is a tap you can refill from in the riders 'D'.
Say thanks to your trainer, he's not getting paid for it.
Listen to the guy in the yellow shirt, he really does know what he's talking about. A girl tonight started arguing with him, I thought she was alright but clearly she doesn't like being told she's wrong, which put me off her a bit.
Never, ever, stop pedalling. In fact, try not to back pedal at all.
Slowing down is achieved by quick look, ride up the banking.
If you're in the train, do NOT accelerate when you get to the front, you'll want to, oh will you want to, but just keep going at the same speed.
Enjoy yourself, it's quite a bit of fun.
