The Vuelta a Castilla y Leon is a professional road cycling race held in Castilla y Leon, Spain, typically in April. It has been contested almost every season since its inception in 1985 as the Trofeo Castilla y Leon. The event is part of the UCI Europe Tour, usually classified as a 2.1 stage race. Recent editions have seen reductions in length, with some run over two or three stages, and a single-day format implemented due to budget constraints.
The race's route varies annually across Castilla y Leon's different localities, rather than adhering to a single, set course. This allows the race to showcase the region's expansive roads, open countryside, and viticultural zones like Ribera del Duero. The competition has featured WorldTeams, ProTeams, continental teams, and national selections. Notable past winners include Miguel Indurain, Alberto Contador, and Alejandro Valverde. Contador holds the record for most overall victories with three, and Alfonso Gutierrez has the most stage wins at ten. The race also included women's and amateur categories, with a three-stage women's event that achieved professional status before its discontinuation.
