Gresp15C

Roughly -20 to +95 F, the range of local temperatures during my commute times over the past few years.

At least 67C, which is just over 120F. I was out in -35C this year, mostly just to say I did it. At least 32C on the high end, which isn’t that hot.

Not many places get as wide a range of temperatures as Alberta.

I commute in Tucson and don't really pay attention to the official temps, I'm more interested in the actual temps out on the road. There are a couple road side bank thermometers that I watch; coldest lately has been 17f, warmest 134f.

Coldest I don't have any. Hottest? 117 degrees, 6% humidity in Scottsdale Arizona. Did a 20 mile ride and hit the wall after I ran out of water. When I got home and grabbed my thermometer, it registered 135 degrees 3 feet off the pavement. "Hot" doesn't begin to explain how hot that was.

Oh, the "dry heat" thing, it's a myth. I live in North Carolina now (have been since 1979 except for the 6 year stint in Arizona) where we have 98 degree days with 95% humidity on a regular basis. Those are hot and sticky muggy rides but they just don't compare to the heat in Arizona.

Approx. 125° F in Iraq in 2010; -15° F in western Illinois in 1976 or 1977

I don't think Minnesota ever sees humidity below 50% .... ever

We've got family up in Edmonton, Hilton, and Jasper. Gotta hand it to you, you get all the weather up there ... and sometimes all in one day.

Minnesota's the same kinda thing, but dialed down, just a notch or two.

Coldest temp was 26F/-3C on a regular pre-dawn, mid-week, mid-January ride when I started at 4AM. Its usually about 45F/6C here on winter mornings in Southern California.

Hottest was 104F/80C in mid-summer along the Santa Ana River Trail here in Southern California during a heat wave while trying out a new touring set-up on an overnight 'credit-card' trip. I started at the beachside end of the Trail when it was 85F at 9AM (that's warm for the beach), temp quickly rose as I went inland and it was 100F after only 6 miles.

The worst thing in the north lands is what happens to the humidity indoors when it's cold outdoors.

High= 109 F (43C) in southern Spainand and in Oregon's High Desert. Low= 28 F (-2C) in Oegon's Willamette Valley

Hottest between 95 - 100F near Spence's Bridge in BC.
Coldest -32C while working as a bicycle courier in Calgary AB. I remember looking up at a big outdoor LED thermometer at the time.

I suffer far more in the heat than the cold.

Hottest I've recorded on Strava: 107F, July 19, 2018, big group ride in Fort Worth. Strava sez we averaged 12 mph over 38 miles, which seemed about right for that heat. We do the Tour de Fort Worth every summer, roughly coinciding with the Tour de France, with rides almost every day ranging from 10-30 miles. Eventually we'll have a couple of crazy hot days.

I recall a shorter, hotter ride of less than 10 miles with the temp up to 110F, but can't find that log. I think it was errands with a few stops, very slow.

Coldest: Maybe 20F a couple of years ago. I usually avoid really cold rides -- gives me sinus headaches. I can handle heat better.

I've commuted at -40C in Manitoba.
I've cycled in temps in the high 30s and it hit 40C on the Gold Rush 1200 back in 2005.

So ... -40C to +40C = 80 degree difference.

Or -40F to + 104F = 144 degree difference.


And just for interest ... I did a century in February 2003 that started at -32C and reached a balmy high of about -25C before cooling down again the next night. It was my longest century. The gears freeze at those temps and the bicycle doesn't move well.

Coldest, for me, would be the winter of 2017/2018. The snow plow had pasted my mailbox and they wouldn't deliver to my door, so I had to go pick my mail up in town (a mile each way). I had this new bike (the Buick) so when the roads were clear and dry enough I rode it to the post office. No records of conditions, but it was still winter. Dressed for a ski-mobile ride: two-piece Frogg-Toggs motorcycle rainsuit and huge snow boots over my regular clothes, ski-mobile gloves with the big zippered gauntlets. Can't remember what I wore on my head.

Hottest? Couldn't say, but probably when I was a kid; we rode bikes all summer and I'm sure it got up into the 90s on some days. I had a pass to a municipal swimming pool a couple miles away, I'd ride there and back and hang out with my friends at the pool and maybe ride around some afterward. I had a trusty Columbia cruiser, a hand-me-down from my older brother, who'd gotten it second-hand.

I spend a lot of time cycling in S E Asia. It can get very hot.

I normally have breaks where I consume frozen drinks and ice to cool my body. If I don't, I can get too hot. When you are too hot, you don't have much energy.

Northern Michigan here so fatbiked once at -10F and that was dangerous. hottest maybe 100F but nothing too extreme.

So far in 2020, 15F to 70F. Boston has wicked bizzah weathah.

+107*f for the last ~70 miles of the GDMBR in NM.

-65*f for a ~50 mile chunk of the Yukon Quest Trail in 2003 -- lasted about 10 hours. Also a week+ of riding/camping on the Iditarod Trail in 2010, where the high temps never got warmer than -35, and the nighttime lows were consistently in the -50's.

My record hot ride was 99F in early Sept 1988. That's was the temp at 12 pm in Arizona when I began a climb into the old mining town of Jerome. That was dry heat. Not as oppressive as heat and humidity during July in Virginia's Shenandoah National Park.

As a young man in Winnipeg, I rode to - 40, but I was getting cold in the minus 30s because I couldn't ride faster to stay warm without freezing my lungs. We really need a face mask to conserve heat and moisture from the breath, without fogging the glasses. It would work for other sports, too.
At 27, on tour in California, I hitchiked across the Central Valley. Pickup truck owners are glad to have some excuse for their extravagance, and had pity for a man standing in the shade of a pole. Toward evening, I was told that I only had to ride half-way around a small lake on a level road to get to a campground. It was not level, but it was so dry that I didn't know I was sweating. I made it around by using bottom granny and coasting. At the State Park, I learned that it was Friday, and all the people standing around were hoping for a cancelled reservation. I filled my water bottle, and poured the first one right over the top of my head. This got some attention, but I just sat on a chain fence and drank another one. Soon, someone came over and said that the Ranger wanted to talk to me. He had arranged for me to share a site with a single fellow who was camping in a pickup cap.
