Here’s how this 103-year-old runner defeated cancer, arthritis without medicines

Veteran athlete Mike Fremont is not just surviving but thriving at the age of 103. Hailing from Cincinnati, Ohio in the United States, Fremont has become something of a celebrity thanks to his remarkable journey. He claims to have overcome both cancer and arthritis without medication, crediting a fully vegan diet for his recovery.A passionate marathon runner, Fremont only took up running later in life, entering races ranging from 10Ks to full marathons. However, his journey into competitive racing began under tragic circumstances. He initially started running to cope with the grief of losing his wife. It wasn’t until 1992—when he was diagnosed with colorectal cancer—that he began racing competitively.
Doctors had given Fremont just three months to live when he was in his late 60s. Instead, he adopted a macrobiotic, plant-based diet and began running marathons. Two and a half years later, surgeons successfully removed the cancerous tumour. His diet, he says, not only helped him beat cancer but also cured his arthritis.
A recent Instagram post by fitness coach Dan Go highlights Fremont’s inspiring lifestyle transformation. “Want to age well and enjoy life? We can learn a lot from Mike,” Go wrote, sharing details about Fremont’s simple but powerful health regimen of diet and exercise.
In a podcast interview with Rich Roll, Fremont revealed how he began studying the ‘Cancer Prevention Diet’ after his diagnosis at the age of 69. He transitioned fully to a plant-based lifestyle—a change that resulted in no signs of metastasis two and a half years later.Fremont’s vegan diet routine

A typical day of eating for Fremont begins with oatmeal, syrup, and blueberries for breakfast. Lunch consists of beans, while dinner includes broccoli florets topped with ketchup.

Beyond his diet, Fremont attributes his longevity to living a low-stress life. He follows a disciplined training programme, running five miles three times a week and incorporating push-ups and pull-ups into his routine. He also believes in using physical activity as a form of emotional release. “It was much better than the two martinis I used to have,” he joked on the podcast.

Fremont also rejects the notion that long life is purely genetic. His father died of liver cancer and his mother of a heart attack. He believes it was his healthy habits—not heredity—that led to his longevity.

Now 103 years old, the retired engineer and climate activist holds several world records in age-group marathon running, including the fastest recorded marathons for runners aged 88, 90, and 91.
