READ THIS!
If you do not get the event pack posted to you then you will have to register in Leeds the day before the event. This is clearly not convenient for many people who might be travelling up the evening before, or even early on the day itself.
If you did not ask for the pack to be posted when you entered the event, you only have about a week to do so! It costs an extra £2.50. (That is £50 it has cost me now, which is a bit steep for the privilege of riding my local roads, but my cousin is coming down from Scotland and it would have been a poor show not to have joined him!)
You should have had an email yesterday explaining this, but you might not have read it!
