El Gran Desafío (2011)

El Gran Desafío (2011) (Spanish for "The Great Challenge") was a major professional wrestling event produced and scripted by the Mexican Lucha libre promotion International Wrestling Revolution Group (IWRG) on July 17, 2011. The event was held in Arena Naucalpan, IWRG's home arena and the venue for the majority of their shows and was the third and final show held under the El Gran Desafío name.

The main event of the show was a best two-out-of-three-falls Lucha de Apuestas, or "bet match" where both Oficial 911 and Multifacético risked their wrestling mask on the outcome of the match. Oficial 911 won, partially with help from Oficial Spartan, forcing Multifacético to unmask and reveal his real name. The show included four additional matches.
