The 1906 Tour de France was the fourth edition of the Tour de France, and the second to use the points system. Taking place from 4 to 29 July, the total race distance was 4,637 kilometres (2,881 mi) run over 13 stages, with the winner averaging 24.463 kilometres per hour (15.201 mph). New to this year's edition were the mountain climbs in the Massif Central. However, like its predecessors, cheating and sabotage still took place. Four competitors were disqualified for taking trains as a shortcut and spectators threw nails on the road. However, this did not stop René Pottier from taking a big lead in the first stages. Free of the tendinitis that had plagued his 1905 chances, he dominated the entire race.
