The longest individual time trial at Giro d’Italia was a 81 km long stage between Peruggia and Terni on 25th May 1951.
The stage was won by Fausto Coppi, who wasn’t entirely in the best shape, after he broke his collabone earlier in that spring. It took Coppi 2 hours 4 minutes and 15 seconds to complete the course. Behind him Louison Bobet finished 2nd and Hugo Koblet, who would make his famous long escape at the Tour de France a few weeks later, 3rd.
Giro d’Italia 1951 was won by Fiorenzo Magni ahead of Rik Van Steenbergen and Ferdi Kübler. Coppi finished fourth.
