The race is typically decided by whoever can climb well and time trial cleanly across three consecutive days. The opening stage often includes categorized climbs that create early separation, while a mid-race time trial exposes weaknesses in positioning or pacing. The final stage usually features the hardest climbing, but by then the GC is often tight enough that a single attack or mechanical can overturn the overall. The short format compresses tactical decisions: teams can't afford to wait, and breakaways that gain time on stage one can survive if the rider is strong enough. Pure climbers need to gain time in the mountains before the time trial, while all-rounders can control the race if they limit losses on the steepest gradients. Recovery between stages matters as much as the stages themselves.
