...was bitten by this in its first year and haven't been back since to find out whether it's improved....
in favour and against:
1. It is a "big city" marathon with crowds at some point of the course, although parts of it are fairly quiet...with approx 8,000 runners which gives you a sense of a big event...
2. It's fairly overpriced and a dull course and with much cheaper and better organised events local to london for the same distance are on offer....you might feel a bit pushed financially...
TBH: The inagural year heavily promoted and relied on the use of the O2 as a "base" for runners which transpired to be a load of nonsense there was no reciprical arrangement with the O2 and I believe it was this type of misleading information that led people to lose faith in the event not the transport issues and delays which were obviously out of their hands...
