One note of correction first: this was a half marathon. The tweet seemed to miss that detail. Doesn't detract from your point necessarily.
Yes, preparations for equipment/clothing is expected, but I think there may be an issue of acclimation--like their bodies weren't ready to adjust for a big shift in humidity.
I have the same inclination about high endurance athletes being more vulnerable to the vex effects. My conflict there is that it didn't seem to impact olympic athletes in the recent summer and winter games. So far, I've mostly heard tennis and soccer players getting most affected. Maybe it has more to do with high endurance with added brief high intensity play.
Does humidity really matter in the low 70s? Most heat index charts don't even go that low because as the temperature drops the perceived difference drops rapidly. At 100 percent humidity 80 feels like 88 but 90 feels like 132. This makes sense because as the temperature rises you become more dependent on evaporative cooling.
I think it's a matter of body temperature, which obviously is affected by outdoor temperature too. In theory, your internal temperature can still run hot, make you sweat, and then still have trouble releasing the warm sweat if it's too humid.
I'm thinking of my time in skiing, and I recalled seeing steam coming off of my friend on a cold morning. My thinking is that if it was also really humid outside, he might not dry off as quickly.

no it's from overworking a damaged heart
