This study analyzes historical results of three different man versus horse races (in Wales, in Virginia, and in California). The data shows that human performance decreases with temperature, but less so than horses, so that 30°C is approximately where the best humans can start outperforming the best horses that year.
I would think that even with 15 minutes of intermittent pauses/checks, that time is still productive for cooling the animal and would add less than 15 minutes to the theoretical total if they were allowed to run the whole time.

The horses also all had humans on their backs. To my knowledge, none of the humans had horses on their backs.

For it to be scientifically accurate of a comparison, the ratio of weight:human needs to be equal to that of rider:horse.
In case my phrasing is confusing, to illustrate what I mean here is an example: a 200lb horse carrying a 100lb human is equivalent to a 100lb human carrying a 50lb weight.

Things don’t scale linearly like that. Many things are proportional to either the surface (so x²) or volume (x³) or complex combinations of those.

Oh true true. I forgot about the square-cube law.
