In his youth, Cartledge greatly appreciated First Responders and the work that they provided for their communities. In 2019, at age 9, he founded
Running 4 Heroes with the goal to honor First Responders that have lost their life while serving their country. His father, Chad Cartledge, is President of the organization. In 2019, Cartledge announced that he would run 1 mile for every police officer lost in the line of duty during 2018, amounting to 148 miles. His ambition was recognized by
Attorney General Ashley Moody, who awarded him her first ever 'Back the Blue Award'. Moody later commented, “Zechariah’s unique and passionate support for the law enforcement community Is admirable. That is why he is the perfect first award recipient for our Back the Blue Campaign. I look forward to following his mission this year and praise him for bringing attention to the ultimate sacrifice these officers made.” In February 2021, Cartledge and Running 4 Heroes sponsored
Mike Harmon Racing's
Bayley Currey for the
NASCAR Xfinity Series opener race at
Daytona International Speedway. In December 2024, at age 16, he ran his 1,572nd mile, the final one he would run for Running 4 Heroes, as he was no longer eligible to participate as a Youth Runner due to his age. Cartledge later referred to this run as "the end of an era" == Racing & Announcing Career ==
