El listado inicial de corredores o pre-lista para la temporada 2021 es una colección de corredores prometedores del World Tour para distintos tipos de terreno. Para ello, a algunos de los que ya han mostrado sus virtudes, se les ha puesto una marca inicial basada en méritos durante las campañas anteriores.
A lo largo de la temporada los corredores podrán adquirir nuevas marcas si superan la barrera de puntos para cada una de ellas durante el calendario.
