That’s why there are programs like Couch to 5K which slowly work up to a nonstop 30 minute run. It doesn’t even take that much determination and it’s practically designed for obese people. I was able to complete it weeks ahead of schedule at a BMI of 30 and the 4-5/wk runs it enabled helped me lose 35 pounds in 2024 - the vast majority of the weightloss happening during the weeks that I ran. Nitpick: a marathon is 42 kilometers (by definition). Most people would struggle to even walk that.
