If I run in the southern heat is that like running at altitude with thinner air?

Yes, exactly the same.
ur an idiot. what the hell do you think?
Second opinion? I mean does it play a role at all? Is the air not thinner in heat?

Yes, the high humidity makes it thinner.
It sounds like this question stems from the Ideal Gas Law: P = (rho*)R*T, where P is pressure, rho is density, R is a gas constant, and T is temperature. Hot air has a lower density, i.e., fewer molecules/less mass per volume, than the same sample of cooler air with the same pressure. Also, air with higher water vapor content is lighter than a similar sample of dry air, because water vapor is relatively light compared to other gases near the surface of the earth. See the periodic table of elements and compare the atomic weight of particles that compose a molecule, e.g., water vapor (H2O) vs. oxygen (O2) or vs. carbon dioxide (CO2).
Yeah, that doesn't answer your question at all, but it proves that I did pay attention in introductory meteorology, physics, and chemistry courses. Damn, I'm freakin' cool! YEAH! Where's my beer?
It's not about the density, it's about the composition. Running in the heat is not related to running at altitude.
Can we talk about how crazy hard this Olympic marathon course is?
