Too hot to ride?

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

It doesn’t for me. Humidity really does make a huge difference. I sweat just thinking about riding in it. When I did Cycle Oregon in 2012, we had a day off in Ashland. I was stunned to learn I had been walking around in 95 degree heat. My shirt was dry. That’s how dry the air was.

Real feel in Philly tomorrow is supposed to be over 100. Dew point around 70. I have no plans to go outside.

Pouring the warm water from my water bottles onto my already sweat-soaked head has not proven to be a huge benefit in a very humid climate. In a very hot, humid climate ... what helps is September.

I work myself into summer, introducing hot rides progressively so that by Julyish I can ride at 100F. Because we don't "do humidity" it's a very different proposition here, where sweat can do its proper job cooling the body and not just soak the clothes and drip (which happens the instant I stop). Don't want to advise for where it's oppressively humid, other than get out and back early.

(Today predicted at 103.)

Don't forget planning that ride early morning or late evening. Early morning is best. On my rides even at dusk the tarmac is radiating at 110°F. Also when it starts getting hot around here, mid July to mid September, I will plan my ride to include watering sources and front yard sprinkler systems.

Oh, yeah, deviating to a front yard sprinkler is a real joy!

heat wave in San Diego, might touch 85 F with about 60% humidity. Way too harsh for a mid day ride.

was only 94F with a little 75% of humidity. The kind of riding where everything clings to you like a booger.

I little rain came through this afternoon and cooled it off enough that I got a ride in. It was my usual 3 laps of Prospect Park. Temps were in the low 80s but still humid. I took it easy in any case because the air quality also isn't great, except after seeing my max watts on my usual sprint segment was 674 I decided I wanted to go over 700w and managed to do it and then left the park and went home. I otherwise kept my HR and watts lower than I normally would in the park. It is supposed to be 95 and muggy tomorrow too.

I got out later than planned this morning; it was 80F at 8AM. I was prepared though, with three insulated bottles that had been half filled and frozen the night before. I topped them off and had cool water even as I got home 2.5 hours later.

I do OK in the heat. In my youth, I did a "Hillier Than Thou" century with 14 climbing. I actually overhydrated - hyponatremia - and couldn't sip an ounce of watee without having to relieve myself. Thankfully, that was the worst of it.

I've found 3 small parks along my Queens loop with sprinklers. Bottle refill at the drinking fountain and stand under the sprinkler for a bit.

These days, I drive to the coast and park.
Drive to the coast and park? Pffft! I refuse to learn a lesson.

I rode to the coast again yesterday, ignoring how hot it would be coming home. I also chose the hot and shade-free return climbs, because I hadn't done them in a while.

High 60s on the coast, and "only" 102F on the final climb up Alpine Road. Yes, I'm an idiot.

Now that 24 hours have passed, it didn't seem that bad.

I call today...summer. Finally. Today, was the first outside ride this year that I knew I did not need a base layer, arm warmers, knee warmers or a wind vest. And I needed sunscreen - yay! I rode along the coast and in a coastal canyon where the temperature was 88 or so. It was no big deal and I did 4 x 30 second max power climbing efforts along the route. The heat felt great.

My wife and I lived in Northwest DC from 1994 to 2001. That was hot and we would run the Capital Crescent Trail but it had to be early. I remember 88 degrees at 11 PM in Georgetown. We had a lot of 90 -100 degree days with high humidity. Once it got hot, no activity was pleasant. We would wake up in the morning and the windows were fogged over from the high ambient and humidity and our house running air conditioning.

We were delighted to move back to California in 2001.

Not to be a wiseacre, but I sweat. No extraordinary measures required. That works pretty well here in the East, even when it's humid. On most rides I'm rarely out in the direct sun for very long (lots of trees), and evaporative cooling due to the airflow of just riding along keeps me cool enough to keep going. I don't know how that would work in very dry environments, or at altitude, or in areas with few trees (mid-West cornfields??). Riding earlier definitely can help, with the bonus of less traffic (and more time to do other stuff during the day).

I've only felt really bad on a hot ride once, and that was my feet (too close to the hot pavement). I should have loosened my shoes earlier than I did.

During rides I usually feel fine, but the rides take more out of me than a cooler ride, even if my muscles feel fine. Sometimes my sleep the night after a hot ride suffers, too.

There's heat and then there's heat with humidity. I volunteer as a first responder. This past couple of weeks in NY, slightly north of NYC, our district had 4 calls to assist cyclists who are experiencing heat exhaustion. One of them passed away. Heat exhaustion and heat strokes are not a joke. They affect people progressively, and many are not even aware of what is happening to them. I would urge all riders to be cognizant of the symptoms. Heat exhaustion strikes first followed by heat stroke.

Know your limits, hydrate yourself, ride with a buddy if you can or let someone know where you will be riding, and if you feel anything off, get into shade, cool down.

Stay safe out there, friends.

This is why I always stayed within city limits on hot days in the past. There is always a subway station nearby. Now I won't go further than the park.

Sun, Heat & Humidity are tough... Having lived most of my younger life in the NYC - Annapolis area. All 3 together really affected how and when I rode, if it wasn't dictated by and set event.
Been her in Ca for 35 yrs now, and Humidity is less of an issue, But Sun & Heat are still a big deal.
One thing which works and can suggest to reduce exposure, help with temp regulation and actually be 'cooling' are Arm sleeves/coolers or a light color (white is nice) longsleeve jersey.
The White sleeves ARE cooler than bare skin and if you sprinkle with water, the additional cooling effect is dramatic ! Plus you'll significantly reduce your chance of skin cancer.
Been using them since 2000. Only time I don;t wear them is when the day/ride is fully overcast (which we get often in Apr thru June, early July as the Marine layer gets sucked inland/coast when the interior desert is burning...).
On longer rides, I'll have 2 water bottles, one might have some electrolyte powder added, but one is always plain water - both for drinking and dousing my neck/head/torso and especially the arms.
I have and use a great assortment of white sleeves, from plain lycra from China to more tech fabric stuff (much more costly).
My Favorites over the years are certainly the DeSoto Arm Coolers

DeSoto Arm Coolers
They're not inexpensive (my take) but if you really want and need to stay cool, they work great, for me.

I've recently also had to wear similar for the Legs, due to a 3 month long allergic reaction rash, due to a supplement I was taking (no longer). Plus the rash was photo-activated, so any sun really intensified the rash and itching, swelling...
I found the Castelli 50+UPF Leg Sleeves were by far the best, and with my very long legs, they are logn enough, well built with good legs bands and zips, to cover and stay in place and do a great job shielding from sun! I hadn't tried their amr sleeves, but given the fabric and performance of the Leg Sleeves; the arm sleeves are prolly quite good also...
Ride On

Watch your heart rate even closer than you normally do, it will be higher than normal, but I just adjust my ride based on heart rate, you can be safe riding in warmer conditions, IF you adjust to them over time, don't go from not dealing with hot weather to riding the 'hotter than hell 100" in August in Mineral Wells Texas,,,,we had a group ride in Dallas one Thursday night last year that it was 105 when the ride started,,,,ok I sat out that ride

Seems like common sense to take a day or so off when the temp/humidity are in the red zone. One must consider the risk/rewards in this situation. Maybe I’m too soft. I am able to ride adjacent to the ocean and am out early and my max ride time is around 3 hours.

I feel the same way here in Texas. Literally 100º, feels like 108 right now. Last year I did that and got heat stroke even though I didn't overdo it, drank extra electrolytes, took breaks, and had 2 water bottles. I don't think the human body is designed for this.

I bought one (and just ordered s second) steek water bottle from Camelback,,,this morning I had one Camelback Steel, and one regular camelback plastic, each had cold gatorade type 'stuff' and one large piece of ice (my ice maker makes "high ball" type ice which fits perfectly. After a 2 hour ride the water in the steel (not the titalium) bottle was still perfectly cold just like when I poured it into the bottle from the refrigerator, took the last drink and could shake the ice still in the bottle. I took a drink from the plastic bottle it was luke warm, not cool at all. These things can make a difference, honestly I found myself driinking more because the water was nice and cold...$40 for something to keep water cold is an investment I will make
