Time do luggage trucks close at London Marathon & what time to be in my pen for?

What time Sunday morning please do the luggage trucks close and also what time in the red start do i have to be in my pen for? Im hoping for a sub 4 hour time so dont wanna get penned in and stuck loo.

What time you all aiming to get to the  assembly area to begin getting ready etc.

thanks

The organisers really do do it all for you, they know most people are nervous and unfamiliar with London so thy make it all very easy.

When I ran in 2007 there was a problem on one of the train lines and a whole trainload of people turned up late. As I understand it from one of them, the baggage trucks had already left but the organisers knew about the delay (they're probably in touch with Transport For London all the time on race day)   and had a contingency plan to have the bags picked up later.

Basically -whatever could go wrong those guys have though of it frst - good luck for tomorrow  

Leave your last piss till the last minute, run like a loon to the start pen with five minutes to go then jump up and down on the spot till they corale you forward for the gun.  Worked for me.
