111 editions into the Tour de France and, despite doping being better policed than ever, the speed of the race continues to go up each year. Science of the Tour de France author James Witts looks into the influence of nutrition, aerodynamics, money, data and youth development on this trend. Before that, we bring you a thorough preview of this year’s race. We answer eight of the big talking points posed by this year’s race, then analyse the hopes and dreams of all 22 teams vying for the spoils of the biggest, most prestigious showdown of the season. In the middle of all that is a huge 24-page preview of all 21 stages, as the race proceeds to the new, seemingly one-off finish in Nice.
