True but cooling from radiation loss is way down in the noise compaired to heat
loss from evaporation, convection and loss from heat transfer from he lungs -
panting. It will not offset the additional heat gain from absorbtion. Now if
the competitions were run at night the dark horses would have an advantage.
However, there are many other factors that can outweigh the disadvantage of
coat color. All other things being equal, the light colored horses will have an
advantage. If you don't absorb the heat you don't have to deal with it.
All that being said, I'll not own a gray horse. I just like a little color.
