Since 1981, Hinault had been joined at Renault by two young talents, Laurent Fignon and the American Greg LeMond. Both joined Hinault for the Vuelta a España, where he faced stiff competition from local riders like Marino Lejarreta, Julián Gorospe, and Alberto Fernández. Six days before the race started, he had won La Flèche Wallonne for a second time. On stage4 of the Vuelta, Fignon attacked and won, but Lejarreta, the defending champion, had followed him and gained time on Hinault. Hinault came back and took the lead the following day on the mountain stage to Castellar de n'Hug. However, a day later, the Spanish teams jointly attacked and Lejarreta moved ahead of Hinault, who was 22 seconds down. At the uphill time trial at Balneario de Panticosa, he suffered and finished more than two minutes behind Lejarreta. Hinault joined forces with Kuiper and Saronni to attack on stage 10 to Soria, affected by crosswinds. He was in trouble again on stage 14, affected by returning pain in his knee; at one point he trailed his rivals by more than five minutes, but regained contact. In the time trial around Valladolid on stage 15b, Hinault won, now just ten seconds behind Gorospe, the new leader in the general classification. The following day brought the last mountain stage and Renault put pressure on Gorospe from early on. Hinault, joined by Lejarreta and Vicente Belda, escaped for , distancing Gorospe by over twenty minutes with Hinault taking victory in Ávila, sealing his second Vuelta victory. Due to the tightly fought battle between Hinault and his Spanish competitors, the 1983 race is described on the Vuelta's website as "one of the most beautiful and spectacular" editions.
