Despite this format, some editions occasionally had more unorthodox courses. The 2014 edition was an unusual race with no time trials or summit finishes. In 2015 organizers returned to the traditional format, starting in Yvelines, west of Paris, before moving south. The key stages were the summit finish to the Col de la Croix de Chaubouret in France's Massif Central on stage 4 and the concluding time trial on Col d'Eze. The 2016 edition included dirt road sectors in the first stage of the race and a passage on the lower slopes of Mont Ventoux in the fifth stage.
