My oldest daughter was a marathon runner. She used to out run the jocks for the fun of it
My sister is 50 years old and still runs an annual ~170 mile super-marathon that takes multiple days to complete.
It’s amazing what people can do. Though she still can’t do a pull-up: she doesn’t have the upper body strength.

Yes, I knew a girl like that. I went backpacking with her once and with a ten pound pack she could not keep up with men carrying eighty pounds.
