Temperature - What's your limit?

Notices
Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Lower limit = 20 degrees F. Upper limit = 95 degrees F.

I'm not a big "numbers" guy, the only thing on my handlebars is tape That said, when I head out in the morning I know an "aw h*ll no" day two seconds after I step out the door.

Philadelphia. We do have our share of good hills here as well, if i feel like riding them on any given day.

Heat.....no limit as I doubt it can get that hot unless hell comes to earth! However, as I get older the cold temps and I just don’t cope very well.

Oh, yes, The Manayunk Wall. I don't think the details on the Strava segment for it really do it the justice it deserves. It gets pretty nasty near the top. I believe it maxes out at 18 or 19% near the top. Fun. 🙂

This is my first summer riding in Miami heat and humidity, I've lived here several years but wasn't riding.
it's hot humid almost year-round.

I was relieved to learn the breeze from riding at INCREASED pace makes all conditions comfortable, I've never yet cut short a ride because of the heat.
After being soaked by a rain shower (common) I sometimes feel a little chilly even in these temperatures and high humidity.

I did invest this year in some good warm weather jerseys to handle the sweat as it was quickly apparent cotton shirts don't cut it.
my only issue is sweat getting into my eyes, I sometimes wash my eyes with a squirt from the water bottle, this might not work as well if you carry Gatorade

If it's below 40F I won't be riding, unless it's for commuting to/from work.

30F without ice to 90'ish. The sweat burning your eyes going up hills is no fun.

Cold sucks. When I was racing I would go out in 40 degree rain and train.
Heat is just a bit annoying. I did one crit in 100 degree heat. Brought 3 bottles with ice water, plus an ice sock in my jersey. I finished all the water in the hour crit, and it was hot water by the time I finished. But I stayed cool enough and hydrated enough to hold a solo break from 5 minutes out to win, so I have to say I don't mind heat!

You would never make it in AZ. It was 90F at 5am, will hit 115F later this afternoon.

Yeah, but that's a dry heat. It's not so much the heat, it's the humidity.

Stick your head in an oven, and tell me how a dry heat feels so pleasant.

We'll be done riding around 10am. The air temp will be 100F(in the shade), but 3ft above the pavement it'll be over 110F.

Yes the dry heat is a lot different than a humid heat. People from dry heat areas totally collapse when they come to the Deep South and ride in 95 degree high humidity. Whereas a person from humid heat goes to a dry heat area and overdoes it because they don’t realize they are being dehydrated due to lack of humidity.

I was in LA County in the mountains at Hazmat City training with the DEA on Level A response for three days. The temps every day were 100 plus and it was a dry heat. I felt fine the whole time but I was hydrating as we had EMT’s there the whole time with our training to make sure we did. We discussed the areas of the country we were all from and the hazards. The dry heat folks stated they would take dry heat any day over our miserable swampy humid 95 plus days in the south.

I would agree with them as I would certainly love to live in that climate and bike.

It is about knowing your environment when riding and your personal acclimation. Lately here where I live, 90’s and high humidity. I still ride even though I am drenched before the first 5 miles! My body is use to this environment. If I lived in dry heat areas, I would just have to train to drink often because I do not realize I am dehydrating.

While I love being in low humidity areas for anything that isn't about long hard levels of exertion. I've wondered if in those climates I'd miss some of the things that clue me into when I'm doing too much too long. I can see me doing too much in some place like Colorado, just because I'm more comfortable and drier.

And just to what if further. Moist humid air is less dense than dry air. So two things for the mathematical and physiological leaning of you out there.
  • Is this density difference making a significant impact on the amount of oxygen my lungs can transpire?
  • Is the density difference making a big impact on drag coefficient?

I did just fine living in Flagstaff. Lived in the Inland Empire for 10 years. Hottest day was 119F. No thanks. You can have it.

No hard limit, but my decisions are made looking at the dew point in conjunction with the temperature. 95F with a dew point below 32F is delightful and pleasant. The same temperature with a dew point in the high 70s will put me in the barf zone.

I use a heart rate monitor to make sure that my body recovers from spikes, especially during and after a climb, and take it easy if necessary.

Yeah - that first one was me. I lived in dry heat climates for nearly a decade, and then moved to the Gulf Coast of Alabama in the summer and tried to do the fast group. I nearly hurled my guts out on the side of the road. That humid heat (and high dew point) means the sweat doesn't evaporate, so you don't cool down and end up an overheated literal hot mess.

​​​​​​Is this true? Dry (weather and air both) is associated with high air pressure, moisture with low.

What many don't understand about "it's a dry heat" is UV factor. Temps matter - and so does being bombarded by endless UV rays from a cloudless sky. Other than spirited attempts to prove one is 'tougher' than another, I'd simply say that "unpleasantly hot is hot."

Checking in from ABQ, where I finished at 105 the other day and know that the reflected heat on an open, hard-surface-fringed route was higher than that. (I used to live in Vegas, where reflected heat often pushed real street temps above 130F during the day).

My biggest issue is hydration. Since COVID, my usual refill places aren't as accessible. I found this out on a 100F day, when I (stupidly) assumed the (previously profoundly appreciated) filtered, spigoted refill station at the public park would be working. Nah; "Park's closed, moose out front should've told you that." Cramps ahoy over the last 12 miles which was NOT fun.

Yes, kinda. Water vapor 18g/mol. Air 28.96. https://www.engineeringtoolbox.com/m...067%20g%2Fmol.

Thing is when you deal with condensing water vapor, that is different. A mist is likely not as fast, and rain certainly is not, add to that the water on the road.
The rider may perform better in drier because they can cool better.
