The Tour is usually won through accumulation rather than one single coup. The route changes every year, but the pattern is familiar: an opening week where crashes, nerves, and crosswinds can already take time; a middle stretch that sends the GC riders into the mountains; and a final phase where summit finishes and a decisive time trial settle what is left. Sprinters can own whole afternoons, but yellow is usually decided by the rider who climbs best, limits losses against the clock, and recovers cleanly enough to do it again the next day.
Three-week pressure
The Tour rewards the rider who can survive twenty-one stages without losing concentration, recovery, or team structure.
Mountains decide yellow
High-mountain stages and summit finishes still expose the deepest climbing strength and the worst bad days.
Time trials still matter
The clock keeps the Tour honest by punishing pure climbers and rewarding the most complete general-classification rider.
Chaos before the climbs
Crosswinds, crashes, and nervous flat stages can reshape the GC long before the race reaches the Alps or Pyrenees.
