Your National Anthem Singer – Jim Diego

Jim Diego is from New York City and is an avid runner, having completed both a half marathon and a full marathon in all fifty states, completing the first round with half marathons in July 2016 after only a little over two years; and the second round for marathons in November 2018 in about four years! He has been highly recognized as a national anthem singer at road races large and small all over the country. Notably, in his home state of New York, he has sung at the start of the 2015, 2017, and 2018 TCS New York City Marathons. As his singing talents began to be recognized at road races, he decided to pursue the challenge of singing the national anthem in all fifty states, accomplishing that feat at the same race he finished fifty states of marathons in Tulsa, Oklahoma. Runners’ World published an article detailing Jim’s journey to running and singing in all 50 states shortly after finishing this challenge! In 2019, he’s shifted his focus to doing international marathons, as well as “bucket list” races – the Probility Ann Arbor Marathon actually falls into this latter category for him, as coming to A2 is somewhat of a homecoming; he went to college at the University of Michigan and graduated with his BS in Architecture in 2006. Though he wasn’t a runner back then, running around the city he knew so well will be quite nostalgic!

Your Announcer – Justin Shelton

A 22 year veteran of DJaying, Justin Shelton has played events large and small; from concerts, art shows and weddings to races, charity events and runway shows.

Shelton earned bachelor degrees from Arizona State University in communications and from Full Sail University in film. During college, Shelton DJ’ed and did play by play for the student radio stations. Since then, Shelton DJayed in Los Angeles for over 15 years while working in film for studios like Warner Bros. Shelton moved to Michigan recently to raise a family.

Lucky for us, that we discovered Shelton as a DJ and spotted a hidden race announcing talent.  We invited him to announce at one of our races and we haven’t looked back!
