Pre-race favourites
The Clásica de San Sebastián is the most important one-day race in Spain. It comes a week after the conclusion of the Tour de France. Some riders, including Chris Froome (), the winner of the Tour, chose not to participate in the race. Riders also arrived from the Tour in a variety of conditions: some were in good form, while others were exhausted. Another of the principal riders from the Tour de France, Alberto Contador (), originally planned to participate but was forced to withdraw because of a fever.
The principal favourite for the race was Alejandro Valverde (), who was third in the Tour de France. Valverde was the defending champion in the Clásica de San Sebastián, having won the 2014 edition with an attack on the final descent; he had also won the 2008 race from a small group sprint. As well as his podium place at the Tour, Valverde had also won La Flèche Wallonne and the Liège–Bastogne–Liège in 2015. The other principal favourite was Joaquim Rodríguez (). Rodríguez won two stages during the Tour and was expected to be in fresh condition, as he did not attempt a high position in the general classification.
Several other riders were considered to have a strong chance of victory. These included Philippe Gilbert (), the winner in 2011, Mikel Landa (), who had been third in the Giro d'Italia, and Julian Alaphilippe (), who had finished second to Valverde in both La Flèche Wallonne and Liège–Bastogne–Liège.
