Overview
- Filippo Ganna dominated Tuesday’s 42 km Viareggio–Massa test in 45'53", averaging 54.921 km/h for the fastest Giro time trial over 40 km.
- The course was almost entirely flat and straight with two U-turns, and dry roads produced ideal conditions for an ultra-quick run.
- Afonso Eulalio defended the overall lead and now holds the maglia rosa by 27 seconds after a controlled ride.
- Thymen Arensman finished second at 1:54 and moved up to third in the general classification at 1:57.
- Jonas Vingegaard struggled to 13th about three minutes behind Ganna and remains second overall, setting up road stages where attacks, not time trials, will decide his gains.
