So far the only ride idea that I've had that I've pursued further than just "random musings" is the Thames Path, with lunch at the wonderful Meantime pub in Greenwich.

But obviously the plan for the day needs to work around which train stations people are arriving into, which so far seem to be Paddington and Euston - both of which are north-ish. So a North London ride would be great, in which case I wholeheartedly second LMNH as the lunch stop.

Unfortunately, I'm not familiar with North London and am not confident that I could put together a traffic-lite (and not too hilly?) ride in that part of the city. So - if anyone would like to help me with planning one, PM me please!
