While the general negotiation with other countries and the specific route were handled by the Organising Committee for the Games, the detailed organisation was delegated to a subgroup led by F.W. Collins. Due to cost implications, the extensive route conducted by the 1936 Games was ruled out. Instead, the simplest route from Olympia to London was to be used, going by sea to Italy and then run through Switzerland and France. The route was modified only when Luxembourg and Belgium both requested that the torch travel their territories. A longer Greek route was planned, but reduced from an expected down to due to concerns over instability in the country and a lack of security.
