Vigil started his coaching career at his old high school,
Alamosa High School, where he also taught for 12 years before becoming a coach at Adams State. During the buildup to the
1968 Mexico City Olympics, Vigil served on a committee to organize the first U.S. Olympic Marathon Trials in Alamosa, which has a similar altitude to Mexico City. He had worked with
Leonard "Buddy" Edelen, the American record holder in the marathon at the time, to convince the
American Athletics Union to host the trials in Alamosa. In 1997, Vigil was head coach of the United States Pan-American Games Team. ==Personal life and death==
