AI quick summary
- Flat stages end in bunch sprints and barely move the overall; mountain stages and time trials decide the GC.
- Hilly and transition stages are where breakaways succeed — the GC teams often let a small group go.
- Time trials are solo (or team) efforts against the clock and can open big GC gaps.

Flat and sprint stages
Flat stages are built for speed: the peloton stays together, controlled by the sprinters' teams, and ends in a bunch sprint at 60+ km/h. The overall contenders finish safely in the bunch, so the GC barely changes. These stages are about stage glory and green-jersey points, not the yellow jersey.

Hilly and transition stages
Rolling, lumpy stages between the big mountains are breakaway territory. With the GC teams unwilling to chase, a small group that escapes early can hold on to the finish — these stages produce the most unpredictable winners and are where the breakaway tactics really matter.

Mountain stages
The high mountains are where the Tour is won. Summit finishes and long climbs open real time gaps between the GC contenders, and a single bad day can end a podium bid. Climbers and GC leaders go head to head here, and the yellow jersey often changes shoulders.
/ 05
Time trials
In an individual time trial, riders start one by one and race solo against the clock — no drafting, no teammates. It's a pure test of sustained power and pacing, and it can reshape the GC by minutes. Team time trials work the same way but as a team, taking the time of an agreed group.
/ 06
Rest days
There are usually two rest days across the three weeks — travel and recovery days with no racing. They're also when the media and fans reassess the GC and speculate about who's fading and who's peaking for the final week.
