We travelled 13 miles today. Well to be more precise we travelled from home to London first then we walked the next 13 miles before returning home. We arrived back home about 90 minutes ago. 
We started from where we left off last time, St Paul's Cathedral, walked down Ludgate Hill, up Fleet Street, turned right into Chancery Lane then turned off into Lincoln's Inn Fields, back down Chancery Lane, across Fleet Street and into Inner Temple.
Then out the bottom of Inner Temple Gardens, along the Victoria Embankment past Cleopatra's Needle and the London Eye to Westminster. From Westminster Abbey up to Birdcage Walk and St. James's Park, past Buckingham Palace back to Horseguards Parade, left along Pall Mall, north to Picadilly and St. James's Church, back along Picadilly to Picadilly Circus, south down Regent Street, left along Pall Mall to Trafalgar Square and thence onto the Tube to get our train back home. 
Our legs are worn down to two short stumps and now, I suppose, I'll have to write a trip report of some sort possibly with the occasional photograph (or perhaps I could get away without writing it).
