• Day 75: Excruciating sacroiliac joint pain

“Faster running eased pain via endorphins, but my body couldn’t sustain it,” he admitted. When urged to quit at 81 marathons, he refused: “81 isn’t 100. I will not surrender.”

Behind the Scenes Heroes

Jin credited:

• Cai Chang (Qiaotou Running Group): Mobilized 30+ volunteers for pre-dawn logistics, medical aid (AED included), supplies, and weather contingency planning.

• Wife: Patrolled the course on her e-scooter post-race to clear debris, while managing nutrition and emotional support. “Half this medal is hers,” Jin proclaimed during an onstage embrace.

• Runners: Provided homemade congee, electrolyte beverage, and fresh fruit daily.

Experts: Admire, Don’t Imitate

Qian Meiyun (President, Wenzhou Marathon Association):

“This exceeds ordinary limits. Future editions should emphasize collective participation, not solo extremes.”

Dr. Luo Guogang (Deputy Director, Sports Medicine Center, Wenzhou Integrative Medicine Hospital):

“Persisting through joint pain risks irreversible damage. A 2023 British Journal of Sports Medicine study showed similar extreme attempts caused 72% injury rates, including Achilles tendon rupture. Amateurs must follow the 10% weekly mileage rule and allow 4–6 weeks’ recovery post-marathon.”

The Catalyst

Jin (formerly 80 kg with hypertension, hyperglycemia and hyperlipidemia) took up running in 2016. Now 60 kg and healthy, he launched Bai Ri Bai Ma during China’s “Weight Management Year” to inspire others. His next goal? 1,000 lifetime marathons.

Today, a commemorative stone stands at Guxi Trail—a permanent tribute to human resilience and the power of Chinese community spirit.
