Overview
- Filippo Ganna won the 42km individual time trial in Massa with an emphatic ride that put him about 1 minute 54 seconds clear of teammate Thymen Arensman and reshaped the standings.
- Afonso Eulálio kept the maglia rosa after the time trial with his lead over Jonas Vingegaard cut to 27 seconds and then extended that margin to 33 seconds after picking up intermediate bonus seconds on Stage 12.
- Thymen Arensman vaulted into third overall on the back of his TT performance, giving Netcompany‑Ineos a one‑two on the stage podium and changing team roles in the GC battle.
- Jhonatan Narváez delivered UAE Team Emirates a morale boost with his third stage win of this Giro as the team pivoted to stage hunting after losing Adam Yates, Jay Vine and Marc Soler to an early crash.
- Rider health and crashes have been decisive so far, and with the only time trial complete the narrowed time gaps mean the upcoming mountain stages are likely to force aggressive tactics that could overturn the current slim margins.
