Knight of Gondor... as cute as the Daniel Boone story is, it could be true as follows. 40 miles per day for 4 days equals 160 miles. 4 miles WALKED for ten hours equals 40 miles per day. So it could be done. At least on paper in theory.
Of course, that has not a darn thing to do with Gimli doing 140 miles in 3 days.
The bigger problem here is that JRRTolkien himself described the activity of Gimli and company as both running and striding. Both activities burn almost three times the energy and gylcogen of normal walking making it impossible to sustain beyond two to three hours for the untrained runner.
