Batbayar Tserendorj, a 60-year-old runner from Round Lake Beach, Illinois, made headlines for postponing a life-saving liver transplant to participate in the 2023 Chicago Marathon. Diagnosed with liver cancer earlier that year, Tserendorj received a call for a matching liver the night before the race but chose to run instead, believing it could help another patient. Nineteen days after completing the marathon, he successfully underwent the transplant. This year, he returned to the marathon, cancer-free and celebrating his 'second chance at life.' His medical team supported his decision, recognizing his determination and the benefits of running for his health. Tserendorj expressed his gratitude, stating, 'Life is not easy... but liver transplant is just a second chance of life.'
