2009-04-26 Sun - 6am London Marathon Ride

thinking we'll definitely have to break into smaller groups, maybe send people off with a half an hour gap in between.

Just a note, be polite to the police and anyone else whose part of the organising of the marathon you come across, we got by with a wave, a smile and a good morning to everyone in uniform. Made for a good morning.

anyone know what time exactly they start closing off the roads and putting up the barriers?

If the official website's correct, then between 7 and 8, depending on the location.

Unfortunately, the road closure timetable they provide doesn't look like it's been updated since 2006.
