Stage 1 saw Matthew Brennan (Visma‑Lease a Bike) win the 165‑km opening route to the Castillo, taking the first purple leader’s jersey after the early breakaway of Josh Burnett, Javier Ibáñez, Valentin Ferron and Unai Aznar was re‑absorbed.

In Stage 2, Oscar Onley (Netcompany INEOS) surged on the final climb to Valle del Sol, outsprinting Giulio Ciccone to claim the stage win and the overall lead, now four seconds ahead of Bjorn Koerdt. The victory marked Onley's first for his new team after a shoulder injury and a crash two months earlier at the Tour Auvergne‑Rhône‑Alpes, which had forced him out of the Tour de France. He described the win as a “great relief” after a season of setbacks.

Enric Mas completed the podium on the second day, while other contenders such as Jonathan Milan and Giulio Pellizzari launched attacks during the stage. The race continues to serve as a key preparation event for the upcoming Vuelta a España, attracting several WorldTour teams and their leading riders.
