Chicago Marathon Runner Completes Race Months After Stage IV Lung Cancer Diagnosis
CHICAGO – Kevin Humphrey of Chicago completed the Chicago Marathon on November 5, 2025, just months after receiving a Stage IV lung cancer diagnosis. The 40-year-old father of two ran the 26.2-mile race with his sons cheering him on,a testament to his resilience and determination in the face of a life-altering illness.
Humphrey initially dismissed a persistent cough as a minor annoyance, but further investigation revealed a far more serious condition. Diagnosed with Stage IV non-small cell lung cancer in April 2025, Humphrey underwent aggressive treatment while simultaneously training for the marathon. His story highlights the frequently enough-subtle initial symptoms of lung cancer and the importance of early detection, even in non-smokers. Lung cancer remains the leading cause of cancer death in both men and women in the United States, according to the American Cancer Society, with a five-year survival rate of only 25% when diagnosed at stage IV.
“It was a really scary time,” Humphrey shared with CBS News. “but I knew I needed to stay positive, not just for myself, but for my boys.” He continued training throughout chemotherapy, adjusting his workouts as needed and leaning on the support of his family and friends.
Humphrey finished the marathon in 5 hours and 38 minutes, a personal achievement made all the more meaningful by his health battle. He hopes his story will inspire others to prioritize their health and to never give up hope, even when facing seemingly insurmountable challenges. The article was edited by Nicole Brown Chau.
