The 1967 Tour de France started on 29 June, and was the first to have a prologue, a short individual time trial prior to stage racing, held in the evening, adding to the occasion. There were had two rest days, in Belfort and Sète. Whereas in previous years the trend had been that the Tour became shorter, in 1967 it was longer, with 4779 km. The highest point of elevation in the race was at the summit tunnel of the Col du Galibier mountain pass on stage 10.
