The 24-year-old from Figueira da Foz, participating in only his second Grand Tour, is the third Portuguese to lead the Giro, after Acácio da Silva (1989) and João Almeida (2020).

Eulálio finished second in the 203 kilometres between Praia a Mare and Potenza, behind Spaniard Igor Arrieta (UAE Emirates), after escaping from the peloton early in the race.
