My grandfather used to point him out every Fourth of July broadcast, same spot near the start line, year after year. I didn't understand why one old guy in a sea of runners mattered until Grandpa said he'd been doing it since before I was born, before my dad was born. 53 of them. That's the kind of number you don't really get until someone stops.

William Jackson "Bill" Thorn was an American high school coach and distance runner, known to generations of Georgia athletes simply as "Coach" and to Atlanta's running community as the "Iron Man of the Peachtree." He finished each of the first 53 editions of the Peachtree Road Race, from its first running in 1970 through 2022, and coached teams to 42 state championships across more than half a century.
Born on 4 September 1930 in Birmingham, Alabama, he graduated from Ensley High School and Birmingham-Southern College. In 1954 he married Mary Patricia "Patty" Walton and moved to Atlanta, where he took his first full-time coaching job at Georgia Military Academy in College Park. In 1959 he became head coach and athletic director at Headland High School in East Point.
After a decade away from coaching in property, construction and a tire business, he returned to the sidelines at Colonial Hills Christian School and Fayette Christian School. In 1988 he and two other men set out to found Landmark Christian School in Fairburn, where he coached football, track and cross country until he retired in 2019 at the age of 88. The school's stadium was dedicated in his name in 1998, and in 2020 he entered the Georgia Athletic Coaches Association Hall of Fame.
Thorn took up running in his forties and was one of the 110 finishers of the first Peachtree Road Race in 1970. As the race grew into the largest 10K in the world, he kept coming back, through injuries, illness and, in 2020, a pandemic that forced him to run the distance with his family instead. In his last years he completed the course with a walker and then virtually from his home. In 2023 he became the race's grand marshal. He was inducted into the Peachtree Road Race Hall of Fame in 1994, carried the Olympic torch twice and published a book about his life titled Thorn.
Bill Thorn died on 21 October 2026 at the age of 96. The Atlanta Track Club announced his death the following day, calling him "a fixture of Atlanta's running community and a living part of the history of the Peachtree Road Race." He was remembered above all for the lessons of discipline, perseverance and faith he passed on to the young people he coached.

My dad watched for him too, every year without fail.
