For 2027 the organiser describes a start outside Whitehall, past historic Westminster, down the Embankment with views of the landmarks along the River Thames, then through the old and new of the City and back to the finish line. It calls the course fast and flat and names Big Ben, Tower Bridge, the Shard, the London Eye, St Paul’s Cathedral and the Tower of London among the sights. The race is on Sunday 4 April 2027.
