Das einzige Einzelzeitfahren der Vuelta a España 2025 führt nun über eine Strecke von 12,2 Kilometern durch Valladolid. Ursprünglich war für die 18. Etappe eine Strecke von 27,2 Kilometern vorgesehen. Allerdings hatte der Rennveranstalter Sorge um die Sicherheit der Fahrer, so dass er den Kurs änderte.
Die Profis starten in umgekehrter Reihenfolge ihrer Platzierung in der Gesamtwertung. Oscar Riesebeek (Alpecin-Deceuninck ) macht den Anfang als erster Fahrer um 14:35 Uhr. Die nachfolgenden Profis starten im Abstand von einer Minute. Die Top 10 der Gesamtwertung starten als Letzte mit jeweils zwei Minuten Abstand zwischen den Fahrern, und Jonas Vingegaard (Jumbo-Visma | Lease a Bike) verlässt die Rampe um 17:17 Uhr als letzter Fahrer.
