This article really crawled under my skin a decade ago and stayed there. If one likes that feeling, this is a great read. If not, do not read.

Nicely written. I liked the Car Talk captions. Would have loved to see larger images though. But I understand this is from 1998.

Up until a few years ago, I could've seen doing this as a worthwhile survival exercise, and to know that I can do it.
Then, without trying, I overheated simply by exercising in a room that I didn't know was 95F.
(Since I've mostly only lived in cold/moderate climates, and had never learned how risky 95F is.)
It was highly unpleasant, in an uh-oh, I can see how people die this way, kind of way.
Now, I actively avoid anywhere much hotter than about 80F.
Just last week, I declined a very interesting recruiting outreach from a CEO in Austin, telling him, sorry, but the weather in Texas is just too hot for me.
I'm ready to repurpose the term "special snowflake".

I hope someone helped the dazed person with first aid. And that other people take the heat seriously. It's right there in the name: Death Valley.

Your reaction to heat is highly dependent on acclimation. I live in Texas and have to re-acclimate every year. Exercising on the first 85º+ day of the year is miserable, but a month later 85º feels quite tolerable, and 95º is doable, though performance suffers.
I grew up playing baseball and tennis in 95-100º weather with high humidity routinely. It wasn't pleasant, but nobody was getting heatstroke, nobody was cancelling games or practices. But on a visit to Montana a few summers ago, I saw that kids' baseball games had been cancelled because the temperatures had reach a dangerous level: 90º (in dry mountain air.) Same human beings, different levels of acclimation, very different safety thresholds.
I've never been in the temperatures described in this article, though, and I don't know what the physical limits of acclimation are.

And the other way around.
I once went to a conference, held in early spring, at a Greek hotel. It was 15 C and the hotel staff had closed the pool as it was "too cold" to swim.
Us Brits were puzzled. The Finns were utterly baffled.

The "trick" I used in GA (not quite as hot as TX, but as humid in that part of GA) was to exercise outside year round. It was rarely so cold that winter running was a problem, and as the temperatures warm up or cool down you naturally get acclimated to the new season. It's worked here in CO as well (though due to an injury I didn't this past winter) with getting used to very cold temperatures (I wouldn't exercise outdoors on our very coldest days, but that's about 1-2 weeks out of the entire winter that I'd stick to indoor only training).

The first exercise at 105⁰ seems insane. A week later bearable.
I recall with some amusement thinking I was coming down with heat stroke one summerbecause the light wind felt chilly on my skin. But then I realized it was only 95 degrees

What really matters is the wet bulb temp. For example, the Death Valley high today was 114°F (45°C) but at an RH of only 3%. That gives a wet bulb temp of ~ 65°F which isn't a problem with acclimation and adequate hydration.
Now if it had been 50% RH, the web bulb temp would be > 96°F which is not survivable by humans for very long because no amount of sweating in that humidity will cool you down.

Bike riding in the heat once caused me to come close to overheating. Stopping, finding shade, pouring water over my head and laying down finally brought my core temperature down in time.
I saw the same things begin to happen to my wife some years later when bike riding in the heat. I did the same for her and all was well.

It is currently - well after sunset - 82°F outside. A couple days ago it was mid-90s in the afternoon, and it should get back to that after the current weather passes in another few days.
Mowing the yard when it's high 90s and muggy and sunny is not as rare an occurrence as I might like.

A young couple and their baby and dog died of overheating on a day hike in California a few years ago.
Interesting that they didn't find the nights too cold for sleeping out. We camped in Racetrack Playa one spring some years back and the nights were bitterly cold with extreme wind.

Desert wind is crazy in the spring. It’s a shame because spring is the most beautiful season there, by far. Just a bit hard to sleep in the gale.

This was done in Summer, not spring. I'd imagine summer nights wouldn't be as cold as Spring nights...

EDIT: And this is what a serious amateur can do on that route: https://www.latimes.com/california/story/2022-03-10/astrophy...
Thousands of people run 50k's without a crew every year, worldwide. Maybe even just within the US, even.
Also, Hummels did his traverse in February; TFA is about doing something in July. In Death Valley, that's a world of difference.
