Sarah Gigante (AG Insurance-Soudal) won stage 4 of the Giro d’Italia that finished atop the 11.2km climb to Pianezze, winning by 25 seconds from reigning champion Elisa Longo Borghini (UAE Team ADQ) and new race leader Marlen Reusser (Movistar).

The 24-year-old Australian climber followed Reusser’s acceleration from a large lead group with 2.8km to go. She went solo on the attack with 1.7km to go on the first-category ascent to leave Reusser, Longo Borghini, and Antonia Niedermaier (Canyon-Sram Zondacrypto) behind.
