A Mall start/finish is of course mooted but focusing the race around the Olympic Park will be tempting so soon after the Games. There are options to head out to Essex, South West London and Kent but the idea that's really grabbed us - and not in a good way - is the route that follows the north and south circular roads around London. Some sections are prettier than others, for sure, but pushing pedals past Wembley Ikea, that snarly bit round Brent Cross and the crappy section forever under road works round the top section at Palmers Green and onto Edmonton... the mind boggles.
The London Marathon shows there's an appetite for this sort of mass amateur sporting challenge and the Mayor's 'Sky Ride' attracted around 85,000 cyclists to the centre of London last autumn so it's sure to be a goer. We'll watch this one with interest and - ahem - remind the organisers of our feedback from the Tour de France Prologue event in 2007.
For the 2 wheeled endurance diehard however, it has to be The Dunwich Dynamo.
