Kind of a Midtown Madness circuit: it starts at St. James’s park, then Buckingham palace and Green Park. A long straight leads to the main overtaking spot at Picadilly Circus. Then via Regent street to Oxford Circus. Then again a straight to Tottenham Court, followed by a long, twisty straight. then a chicane at Trafalgar Square, that leads to Embankment. Turn right a the Big Ben to the start/finish straight.
