Primoz Roglic secured a dramatic victory in the fourth stage of the Vuelta a España, showcasing his recovery from a Tour de France crash. Roglic, a three-time Vuelta winner, surged past Lennert van Eetvelt in the final meters of the grueling climb to Pico Villuercas, claiming the red jersey and an eight-second lead over João Almeida in the general classification. This stage marked the race's first entry into Spain from Portugal, with extreme heat and steep gradients challenging the riders. Defending champion Sepp Kuss and former race leader Wout Van Aert fell behind significantly. Roglic's victory was unexpected as his team had not intended to push for a stage win. Despite battling a lingering back injury, Roglic's performance signals his strong contention for a fourth Vuelta title.
