Stage races One-day races and Classics José Humberto Rujano Guillen (born 18 February 1982) is a Venezuelan road bicycle racer who competed professionally between 2003 and 2013, and most recently competed for Venezuelan amateur team Osorio Grupo Ciclismo.

Born in Santa Cruz de Mora, Mérida, Rujano made his debut in the professional peloton in 2003 with the Colombia–Selle Italia team.

[2] At the end of 2010, Rujano signed a contract for two years with the Italian team Androni Giocattoli, directed by Gianni Savio who said that he "believed in his talent" and wanted "to revive his career."

Rujano was recruited at the same time as the Italian climber Emanuele Sella, Savio referring to giving these two riders a "last chance".
