2011-04-16 Sat 9pm - London Marathon Ride

I'd actually be in favour of an earlier start... say 6:15 or 6:30. Lats year a lot of people were stopped from getting to the Mall.

Unless a good pace can be really guaranteed (it can't) then an earlier start is probably a better thing to do.

I agree, but too early and the roads will still be open (though I guess there isn't much traffic at 6am on Sunday).
