Certainly everything in that article is as anecdotal as my statements.
The article is written by an ultrarunner who coaches ultrarunners who run the Badwater. True, it's not a double-blind RCT. It's a report on what has worked well and what has not worked so well for individual runners he has coached. I thought the what worked for heat training section fairly instructive. It can be windy in Death Valley. A few years ago the Furnace Creek 508 had crosswinds estimated at 60 mph. Most riders rode on anyway. Heat training works, and not only for hot weather. It improves performance in all temperatures.
I recall doing a pass climb in 100+ with a tailwind, the sweat from my nose dripping directly down onto my top tube. Luckily the top of the pass was only 85, which was still quite warm. That was Cayuse Pass, RAMROD, don't remember the year, but that was the year when I vowed I would work a lot harder on hydration in the first 3 hours of the ride.
