The race builds across four days, with the opening stages typically favoring sprinters or breakaway specialists before the route turns upward. The decisive stage is almost always a Pyrenean mountain finish, often featuring multiple categorized climbs and a summit arrival that can create gaps of several minutes. Time bonuses and positioning in the earlier stages matter, but the general classification is nearly always settled on the final climb. Teams use the race to rehearse Tour de France mountain trains, so expect to see domestiques setting tempo on the lower slopes before leaders attack in the final kilometers. The mid-June timing means heat can be a factor, particularly on exposed valley roads leading into the climbs.
