Captain America, Thor, Black Widow and Hawkeye, along with a contingent of S.H.I.E.L.D. agents, will be out for both Avengers Super Heroes 5K and Half Marathon this weekend at the Disneyland Resort. This will be the first time both Black Widow and Hawkeye have appeared at a Disney Park. There is no word if these characters will be appearing at any other place or time following their debut.
