Eh, within 15 miles or so. 4MPH * 24h = 96 mile circumference circle, 96 miles / 2pi ~= 15 miles.
You are going to struggle to walk at 4mph in Antarctica

I think you could for a few moments at least. Of course if this is an endurance race, you're destined to lose ;)
That’s why we need global warming!

~24km.
You can do that in a conventional jet at latitudes far from the equator. You can walk faster than the earth rotates if you're very close to a pole (very very close).
