It isn't a matter of just taking longer strides, tell him to watch Japanese marathoners. They take short strides yet they seem to run faster than many others with longer strides. And If aerobic capacity is all that your running performance relies on, then Michael Phelps could run a marathon in 1:45.......
You could use literally any physical activity to disprove this theory.
Different biomechanic. But even short striding runners need a longer stride to go faster.
And your Michael Phelps/aerobic capacity idea is wrong too.
The top athletes don't have superior aerobic capacity per se. There is a lot more to it than that.
