The 20th stage of La Vuelta 2026, presented as the final mountain stage of the race, includes more than 5,000 meters of cumulative elevation gain. This means riders will climb a total of over five kilometers in elevation throughout the stage, making it one of the most physically demanding parts of the race. Fernando Escartin, a former professional cyclist, described the stage as "very difficult," emphasizing the challenge of the double ascent of Hazallanas, a 1st category climb, with another 1st category climb, Purche, in between. These classifications indicate the difficulty and steepness of the climbs, with 1st category being one of the higher levels in the race's grading system. The stage will test cyclists' legs as they face the final ascent to Collado del Alguacil, a climb over 8.3 kilometers with an average gradient of 9.8%. This steep incline will require significant endurance and strength, as riders push themselves to the limit in the final days of the race. The fictional departure time for the stage is set at 12:30, with an estimated arrival time of 17:16, allowing for roughly five hours of racing across the challenging terrain. Among the favorites for the stage are Enric Mas, Primoz Roglic, Felix Gall, and Richard Carapaz, all of whom have shown strong performances in mountain stages throughout the race. These riders are known for their climbing abilities and are likely to be among the top contenders for the stage win. The stage will be broadcast live from 12:30 on Eurosport 1, allowing fans around the world to follow the action as the race heads into its final days. This final mountain stage is crucial not only for the overall standings but also for the prestige of winning the stage itself. With the cumulative elevation gain and the challenging climbs, it is expected to be a decisive moment in the race, potentially shaping the final results and determining the overall winner of La Vuelta 2026.
