A Charlotte architect with a love of Charleston decided to enter the Cooper River Bridge Run T-shirt design contest in 2010 but kept putting off the finishing touches on his work until this year.

And when 37-year-old Marcus Terry finally completed it, he wasn’t sure if it would be a winner. “When you’ve stared at something for three years, you just don’t know if it’s good or not,” said Terry, even though friends and family assured him it would win.

They were right.

For the honor, Terry received $1,000 and the recognition of having his design grace more than 40,000 T-shirts and other promotional materials for the 37th annual event.

Terry’s design, selected from 73 entries a month ago, featured the bottom of a running shoe with a tread composed of one of the bridge’s “diamond” towers and the name of the race. Bridge cable emanates from the shoe.

Terry, who has participated in several Bridge Runs and enjoys renting a bike and tooling around downtown, wanted the design to make a statement about the run using a bridge usually dominated by car traffic.

While it’s rare for a Bridge Run design not to show the bridge in an obvious, prominent way, using a shoe as the centerpiece isn’t unprecedented. The designs in 1999 and 1991 featured shoes, too.

Terry was thrilled to hear the news, particularly after seeing all the other designs displayed online for first-ever public voting for the contest. He noted that he thought a half-dozen were “really solid entries.”

“This is a huge deal for me. I’ve won some other, smaller design contests, but this is the biggest,” said Terry, who attended Wednesday’s unveiling ceremony at Alhambra Hall in Mount Pleasant.

The celebration will continue on Bridge Run weekend when he and a dozen family members, including some from Delaware and Washington, D.C., plan to come down for the event, set for April 5, 2014.

For the Kids Run & Wonderfest, the Bridge Run design selection team chose a design created by the late Peyton Moore, a 9-year-old who died on June 4 shortly after suffering a likely seizure in his sleep. Moore was an athletic, creative child who inspired his parents, Jennifer and Noah Moore, and many others to lead healthier lives.

Peyton was a regular participant in both Bridge Run events and the Charleston Marathon’s kids marathon, which includes a 25-mile cumulative run capped off by a 1.2-mile run the day before the regular marathon. The marathon also is using a design, a different one, created by Peyton for its kids run this year.

Noah Moore said he and Jennifer are honored by the Bridge Run’s tribute to their son.

“Neither one of us had any idea that Peyton would inspire us to make so many changes in our lives, nor did we ever imagine that he would inspire so many others to do the same. Having the running community embrace our little boy is a gift for which we are very grateful,” Moore said.

“Peyton drew the things that he loved, and he loved that bridge and he loved Charleston. Although it does not dull our pain or fill us with the happiness of his infectious smile, having both of these major races include our son’s artwork is something we will cherish.”
