Strategy is only good for really, really good runners.

At ~160m, (similar to the 200m), at-pace speed for the pro is already all-out for the average person.

At 10,000 meters, "at-pace" for the Pro is already faster than 100m sprint for the average (Western, sedentary) human.

Do the BOTEC yourself, you'll see.

There was a display at an airport I read about. Had a projector showing the average speed for a champion marathon runner. Most normal people couldn't match it over the short distance.

Couldn't find the link but here is a similar video of people (mostly amateur runners) trying to match a 2h marathon time for two minutes:
