In Zhengzhou, Henan province, a male runner was caught on video dragging a 9-year-old child during a marathon event. The organizing committee responded by disqualifying the runner's results and banning him from competing for three years. Experts highlighted the risks to a child's health from running such a high-intensity event, noting the child's underdeveloped body and lack of heat regulation capabilities which could affect various bodily functions. Video footage showed a male runner attached to a child with a rope during the marathon on October 18. According to the marathon's rules, full-distance runners must be at least 20 years old, and half-distance runners must be 18 years old. The rules emphasize that marathons are strenuous long-distance competitions that could pose risks to participants. Running marathons as a minor is seen as particularly risky. Doctors, quoted in The People's Daily, have emphasized that children and teenagers’ bodies are not fully developed, and running marathons could lead to risks like fractures and bone cracks. Additionally, children’s hearts are not fully developed, meaning they may face hidden health risks.

There have been reports of more such incidents in other international marathons, leading to calls for stricter regulations and oversight to prevent such practices from continuing. The incident in Zhengzhou has sparked discussions on the ethical boundaries of competitive running and the need to protect young participants. Moreover, the case has reignited debates over the suitability of children running full marathons, with health experts urging caution and suggesting that alternative, less strenuous activities be offered for young runners.
