I know there are a lot of cyclists out there. But did anyone know today is Walk to Work Day?

Now I do walk to FH station, then walk from London Bridge to St Paul's in a feeble effort to combat the effects of my chosen lifesytle of sitting-on-the-sofa-watching-Eastenders-while-drinking-wine.

But I wonder how long it would take to walk to the City from FH? I would say two hours.
