I did a group ride yesterday and it hit 102*. I went for a solo ride this morning and it was in the mid 90's, 94 to be exact, by 9:30 but at least there was a 10 mph wind, too bad it was out of the south!!! I finished about 45 minutes ago and it was only 96*.

I know I have a hard time motivating myself in the winter when it gets down into the mid 50's but I don't seem to have any problems riding in the summer when the heat index could be double that! Yea, I get awfull hot but the Camelback Insulated bottles along with the one's from Klean Kanteen https://www.kleankanteen.com/products/klean-kanteens.html provide enough cool water to keep me going.

My wife thinks I'm crazy, am I? OOPS! I don't think I should ask that question here.... Hey....the weather channel just said it should cool down to the low 90's by next weekend!!! Wooo Hooo cold snap!

After my ride on Friday, about 98 degreese and 98% I was starting to feel the effects of heat exhaustion. This was a 26 mile ride with a stop in the middle for lunch. By the time I got home I had drained a 70 oz. Camelback plus 2, 20 oz soft drinks I had with lunch. In my opinion it's officially too hot to ride in the middle of the day. I will have to start earlier so I'm done before noon or wait until after 7 pm to ride.

It was the soft drinks that did you in. The stuff in them can cause you to dehydrate.... experience....

I don't like riding with a Camelback, so, if I'm on my DF, I have three water bottle cages and they each have a 27 oz. insulated bottle in them plus an extra one in my trunk rack, for a total of 108 oz., just a bit under a gallon of liquid. One of the bottles has a mixture of Amino Vital http://www.amino-vital.com/ plus water. I almost always finish all of them plus I refill whenever I'm able to. My Stratus also has 3 cages on it. Never ever alcohol or soft drinks!

In the heat of the summer in Phoenix, with temps above the 110° F mark, I don't usually ride during the day.

The one exception is my commute home just after 4:00 PM. I have three bottle cages on the EZ Sport and two on the Giant. I begin hydrating myself around 3:00 PM, maybe have a little salty snack to help with the process. I fill my 24 oz. bottles with ice water just before I leave. Since my ride home is only about 35 minutes, I have plenty of water, no matter which bike I'm riding.

On recreational trips, I keep an eye out for water sources as a result of the force of habit of backpacking in the Arizona desert for over 40 years. No matter where I am, I try to make sure I always have at least one full 24 oz. bottle. I'll even stop into a convenience store and buy a large water bottle out of their cooler if I haven't passed a hose bib or a drinking fountain I can use.

Caution is the key to riding in the heat. If I don't see some shade a half mile down the road, I'll stop in some shade and drink and relax a bit before I proceed.

It's funny, I've been riding a bike in Arizona, off and on, ever since I was a kid, and I've done it without having a spare tube or first aid kit for the vast majority of the time. (I just haven't had too many problems with flats or crashes.) But I've ALWAYS had some water with me, having suffered heat exhaustion a number of times. I see a lot of folks equipping their rides just the opposite: lots of tools, very little (or no) water.

What's that line about "Mad dogs and Englishmen"? Maybe we could change that to "Mad dogs and Bicyclists"... Here in South Carolina the heat and humidity in summertime make for a pretty lethal mix if one isn't careful. Here's an idea - what about keeping some rubbing alcohol (in a well-labeled bottle, of course, to prevent accidental ingestion) with which to anoint oneself (on the shirt, not the head - keep it out of the eyes) and experience the exquisite coolth (opposite of warmth = coolth) of the evaporation? Anyone ever tried that?

I for one hate to ride when its cold. For me that is anything below 65. On the other hand I do ride when it is around 100 give or take a few degrees. I carry two of the large water bottles, and stop at most of the the water stops on the trails. The only time I really feel hot is when I stop. Im one of the lucky people for my age 71. BP around 122 over 68 and resting heart rate about 55. Biking when you have high BP etc probably isnt good at high temps.

I ride when it's hot and I ride when it's cold. Leaving the house at 5:00 AM, it can be in the mid thirties for a low in the wintertime. Leaving work at 3:0 PM in the summer, it can be 105. Like somebody else said, while you're moving, it's not bad. It's the stops with no air moving and the heat radiating off the asphalt that gets you.

The highest temperature in the day time here gets around 28°C doesn’t happen so often.
There is no problem of riding but I can’t go as fast as when it’s 22°C. On the “hot days” riding in the evening is great it doesn’t get dark before 23.
In the past winter we had only two days when it was -14°C the temperature was often around -3°C. Dressed correctly I don’t have any problems riding in the winter.
This time of year is great here for cycling.
The temperature today is around 20°C clear blue sky and we had a lovely weekend.

I've been spoiled by this June: had 14 days when it didn't break 100° F.

Gawd, I was tempted to ride NAKED to work!
