, the location of the finish of the race In August 2021, race organisers confirmed that the 2023 event would take place on 23 April; the
2020,
2021 and
2022 events were all held in autumn due to the
COVID-19 pandemic. The winners of the elite events received $55,000, and prizes were given to the top 10 finishers. The total prize money for each elite event was $313,000. The prize money for the winners of the wheelchair races was increased by $10,000 to $45,000, with total prize money for each wheelchair event increased from $199,500 to $253,500. For the first time, competitors in the mass participation event could register as
non-binary; there was no elite event for non-binary competitors. 118 non-binary competitors signed for the race. There was a virtual marathon held on the same date as the in-person event. In the United Kingdom, the races were broadcast on
BBC One, and it was broadcast in 197 countries. The London Marathon was run over a mainly flat course, starting in
Blackheath. The course began at three separate points and they converged just before into the race. At just after into the race, the runners reached the 19th-century
clipper Cutty Sark docked in
Greenwich and at about halfway into the race, the runners crossed
Tower Bridge before heading east into
Shadwell and
Canary Wharf. After winding through Canary Wharf, the route returned through Shadwell on the other side of the road to which it entered before passing through
Tower Hill. The runners entered the underpass in
Blackfriars before running along the
Thames Embankment, past
Westminster and onto
Birdcage Walk. The course then ran parallel to St James's Park before turning onto
The Mall and finishing in front of
Buckingham Palace. ==Competitors==
