Hi, The only info I have is that the gates open at 08:30 and it's free entry, unless you want to ride the runway.
Taken from the mail sent to me,
Gates open at 8.30am and we’re aiming to have the first bike away at 10.30am after a generic safety briefing for all who are there beforehand.
I won't be riding on the day, I've tried fitting into my one piece and zip together leathers, not a chance

with this in mind there's not much point in me getting there before 10:30.
According to Google maps, it should take around 50 mins to ride there, do you want to meet at the services for 09:30?
Oh, and the weather forecast is looking good.
What's your plans?
