The 1921 Tour de France was the 15th edition of the Tour de France, taking place 26 June to 24 July. The total distance was 5,485 km (3,408 mi) and the average speed of the riders was 24.720 km/h. The race was won by Belgian Leon Scieur. The Belgians dominated the entire race, partly due to the absence of the French Pélissier brothers, who were on bad terms with the Tour organisation. Scieur's victory was largely uncontested; Hector Heusghem came close after the sixth stage, but lost time later. The organisation tried to get the cyclists to attack more by several means, but this failed. 15 stages, June 26 – July 24, 1921; 9 riders wore yellow. Wiki link
