AI tells me the average woman marathon runner does it in 4:48.
Article says she has a part time job and has a family of 5. Also has a hamstring injury.
I say she’s nuts. She’ll need knee replacements very soon
In that case, she can transition to cycling.
Running is not bad for your knees - 80s myth, like when they thought fat and eggs were bad. Running is good for connective tissue.
That said, I would think running a marathon every day would be hard on the body in other ways.
