The Earth spins left to right, or West to East. So if you are running in a Western direction, you are effectively running against the spin of the Earth.
Track races are run from left to right, so it gives 100m sprinters an advantage.
For example, Matthew Boling ran 9.98 as a teen, in an unusual track which had the 100m right to left. How much faster do you think he would have ran that day left to right?

Almost all tracks oriented north-south, meaning the homestretch entirely downhill (toward the South Pole) while the backstretch is uphill (toward the North Pole). This has a much greater effect on 100m times than the spin of the Earth.
You are correct. When running west take longer strides to allow the earth to spin under you while aloft. When running east maintain longer ground contact and use shorter strides to allow the earth to propel you.

Right, you have to be careful though to slow down in time after the finish line lest you should go downhill past the equator and just skid off the southern hemisphere into the abyss of turtles underneath.
You are timed in your movement relative to points fixed along the ground, and your inertia is the same as those points in your rotation around earth's axis, so it makes not difference in which way you run. The atmosphere does not adhere perfectly to the same motions as mass on the ground which is part of what creates typical and consistent wind patterns across the globe, so this wind might just add wind resistance if it is blowing against you.
Don’t forget Coriolis force, which gives runners (particularly 200 m sprinters) running on tracks in the southern hemisphere a bit of help making the turn. Perhaps training south of the equator is a disadvantage for competing in the north?

FWIW, as a thought experiment, if you could technically hover in the air suspended for a long time with the help of a jet pack blowing air downward or similar, there is only inertia and the atmospheric air pushing you along. Inertia will cause you to move tangentially, not along a circular trajectory needed to stay stationary relative to earth because there is no gravitational centripetal force by assumption. So the air force is the only force acting to keep you moving circularly with the rotating earth.
In the above hypothetical, a sufficiently dense and heavy object could have too small a surface area to interact with atmospheric air and will start to drift tangentially as well as fall behind the earth’s rotation.

I always wondered why the tracks in Australia went the other way, I had assumed it was the Coriolis effect.
The earth spins at roughly 1000 mph, so a sprinter running against the spin of the earth is going roughly -975 mph. That's unfathomably slow. ALWAYS run with the spin.
