Incorrect. Training in heat has similar effects as training at altitude.

We are the first to conclusively demonstrate that heat acclimation can improve aerobic exercise performance in cool-temperate conditions. These heat acclimation benefits may be retained for 1 or 2 wk, and the rate of decay for heat acclimation will depend on many factors like fitness level of the subjects, environmental conditions where the subjects live, and intensity and duration of their training post-heat acclimation (40). Our findings are analogous to “live high and train low” concepts developed by Levine and Stray-Gundersen (22) but might require less time and logistical support. Our research and that by Levine and Stray-Gundersen (22) demonstrate that robust adaptations to environmental exposure can be leveraged to augment aerobic performance in highly trained athletes.
Anecdotally as I (used to pre-covid) ride 12mi every summer weekday in 105-120F heat I found a significant benefit in fitness that translated to longer and harder rides relative to peers who avoided heat.

I like how that shows what (color) wax to use, but I don't understand why it goes above 40F?

Living in Massachusetts I've done various Autumn rides where the temp was in the 20's. If you're dressed to be warm on the descents you'll be roasting on the ensuing climb and if you're comfortable on the climb, you'll be freezing on the way down. I've generally opted to be comfortable on the climb and therefore cold on the descents. And there's nothing "flat" around here.

On the other end... Days in the 90's are pretty rare. I'd stay inside if the forecast was for a high of 95. Even for a high of 90 I'd be trying to start as early as possible.

I was doing a cycling tour in Utah one time and we had a century day heading towards Lake Powell... 100 miles across a desert with no shade? Ugh. I don't recall the temps, but that was one of the more brutal days I've ever had on a bike, temperature wise.

Pretty much ...

-40 to +40.

I like hotter, preferably between 85F and 95F. I think my limit would be about 105F, I have certainly rode in the 100s. Lower limit is around 45 these days.
However I do not do a lot of climbing here in the Midwest, < 1000 feet, and will try to limit direct sun exposure and climbing in > 90F.

LOL :50:
I know from experience that red wax doesn't got to 120F.

110F uphill with a facemask on! Oh my God that has to be hell !

I could never cycle with a facemask on, I find it suffocating enough just walking in a store with it on.

What about midnight?

I live in NE Indiana, I can handle 95 on the high range, and 40 on the low range. I don't wear a facemask while riding, I don't have that kind of fear when no one is close.

It rarely gets below 80 with 70-80% humidity in Guam, even for early morning rides. It is usually 90-95 in the afternoons for my weekday rides with the same humidity. I can't wait to get to normal riding weather.

It is Summer here in Portugal and while I don't live in the warmer midlands, the coastal regions get quite hot too. It was 95-105 F on my ride mid-day on Thursday. That was my limit since it was tough to train properly. Just cycling like a tourist, no problem, but to train I prefer cooler. The wind was like a hot blow-dryer!

Generally I ride at 6h30 now so that I am home before noon.
