1913. The flamme rouge that was introduced in 1906 to indicate the final kilometre of a stage was kept and is still in use. René Pottier would not defend his title in the 1907 Tour de France, because he would commit suicide before, after discovering that his wife had had an affair while he was riding the Tour. Petit-Breton and Georget would start again in the 1907 Tour and duel for the overall victory, which would be won by Petit-Breton. To honor Pottier's achievements on the Ballon d'Alsace, a monument was placed for him on top of that mountain.
