So, what in here is not consistent with what I said??
Nothing. I did not dispute what you said.
However your comments about the certainty that they were referring to the Heat Index provided no confirmation. That was your supposition (as was what I had already considered).
So I expanded my remarks for clarity and thought the thread might receive a post from someone AT the race who could provide confirmation as to the temps. As UbanKnight mentions, the temps in the town might be much different than other desolate spots. (I might ad as he inferred, due to topography)
